Objective: To evaluate the association between vitamin D status and CV disease after COVID-19 in college athletes., Design: Retrospective cohort study., Setting: National College Athletic Association Division-I college athletes from a single academic institution., Patients: A total of 157 athletes (60 female; median age: 20 years) from 9 sports with a positive SARS-CoV-2 test, cardiac magnetic resonance imaging (CMR), and vitamin D level., Independent Variables: Serum 25-hydroxyvitamin D level (primary); age, sex (regression models)., Main Outcomes Measures: Differences in age, sex, race, ethnicity, myocarditis, pericarditis, and CMR metrics by vitamin D status were analyzed. Regression models were used to assess the relationship between vitamin D status and CMR metrics accounting for age and sex., Results: Low vitamin D (LVD) was found in 33 (21.0%) of athletes, particularly Black males (P < 0.001). Athletes with LVD had higher biventricular and lower mid-ventricular extracellular volumes, but these differences were not significant when corrected for age and sex. Athletes with LVD had higher left ventricle (LV) mass (P < 0.001) and LV mass index (P = 0.001) independent of age and sex. Differences in global circumferential strain were noted but are likely clinically insignificant. Vitamin D status did not associate with myocarditis and pericarditis (P = 0.544)., Conclusions: LVD is common in athletes, particularly in Black males. Although athletes with LVD had higher LV mass, cardiac function and tissue characterization did not differ by vitamin D status. Future studies are needed to determine if the differences in LV mass and LV mass index by vitamin D status are clinically significant. This study suggests that vitamin D status does not impact the development of myocarditis or pericarditis after COVID-19 infection., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: We sought to determine which aspect of the upper instrumented vertebrae (UIV)-tilt angle or screw angle-was more strongly associated with: (1) proximal junctional kyphosis/failure (PJK/F), (2) other mechanical complications and reoperations, and (3) patient-reported outcome measures (PROMs)., Methods: A single-institution, retrospective cohort study was undertaken for patients undergoing adult spinal deformity (ASD) surgery from 2011 to 2017. Only patients with UIV at T7 or below were included. The primary exposure variables were UIV tilt angle (the angle of the UIV inferior endplate and the horizontal) and UIV screw angle (the angle of the UIV screws and superior endplate). Multivariable logistic regression included age, body mass index, osteopenia/osteoporosis, postoperative sagittal vertical axis, postoperative pelvic-incidence lumbar lordosis mismatch, UIV tilt angle , and UIV screw angle., Results: One hundred and seventeen patients underwent adult spinal deformity surgery with a minimum of 2-year follow-up. A total of 41 patients (35.0%) had PJK and 26 (22.2%) had PJF. (1) UIV tilt angle: 96 (82.1%) had lordotic UIV tilt angles, 6 (5.1%) were neutral, and 15 (12.8%) were kyphotic. (2) UIV screw angle: 38 (32.5%) had cranially directed screws, 4 (3.4%) were neutral, and 75 (64.1%) were caudally directed. Both lordotic-angled UIV endplate (OR = 1.06, 95% CI = 1.01-1.12, and P = 0.020) and cranially directed screws (OR = 1.19, 95% CI = 1.07-1.33, and P < 0.001) were associated with higher odds of PJK, with a more pronounced effect of UIV screw angle compared with UIV tilt angle (Wald test, 9.40 vs 4.42). Similar results were found for PJF. Neither parameter was associated with other mechanical complications, reoperations, or patient-reported outcome measures., Conclusions: UIV screw angle was more strongly associated with development of PJK/F compared with tilt angle. Overall, these modifiable parameters are directly under the surgeon's control and can mitigate the development of PJK/F., Clinical Relevance: Surgeons may consider selecting a UIV with a neutral or kyphotically directed UIV tilt angle when performing ASD surgery with a UIV in the lower thoracic or lumbar region, as well as use UIV screw angles that are caudally directed, for the purprose of decreasing the risk of developing PJK/F., Competing Interests: Declaration of Conflicting Interests : The authors report no conflicts of interest in this work., (This manuscript is generously published free of charge by ISASS, the International Society for the Advancement of Spine Surgery.

Study Design: Retrospective analysis of prospectively collected data., Objective: To examine the combined influence of preoperative sleep disturbance and depression on 12-month patient-reported outcomes after lumbar spine surgery (LSS)., Summary of Background Data: Psychological and behavioral factors are considered major risk factors for poor outcomes after LSS. However, there is a need to explore the combined effects of preoperative factors such as sleep disturbance and depression. Understanding the influence of sleep disturbance and depression can inform evidence-based preoperative assessment and shared-decision making of preoperative and postoperative treatment., Methods: Data from 700 patients undergoing LSS were analyzed. Preoperative sleep disturbance and depression were assessed with PROMIS subscales. Established thresholds defined patients with moderate/severe symptoms. Outcomes for disability (Oswestry Disability Index) and back and leg pain (Numeric Rating Scales) were assessed preoperatively and at 12 months. Separate multivariable linear regressions examined the influence of each factor on 12-month outcomes with and without accounting for the other and in combination as a 4-level variable: (1) moderate/severe sleep disturbance alone, (2) moderate/severe depression alone, (3) both moderate/severe sleep disturbance and depression, (4) no moderate/severe sleep disturbance or depression., Results: Preoperative sleep disturbance and depression were associated with 12-month disability and pain ( P <0.05). After accounting for depression, preoperative sleep disturbance remained associated with disability, while preoperative depression adjusting for sleep disturbance remained associated with all outcomes ( P <0.05). Patients reporting both moderate/severe sleep disturbance and moderate/severe depression had 12.6 points higher disability and 1.5 points higher back and leg pain compared with patients without moderate/severe sleep disturbance or depression., Conclusions: The combination of sleep disturbance and depression impacts postoperative outcomes considerably. The high-risk group of patients with moderate/severe sleep disturbance and depression could benefit from targeted treatment strategies., Level of Evidence: Level II., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Study Design: Retrospective analysis of data from the cervical module of a National Spine Registry, the Quality Outcomes Database., Objective: To examine the association of race and ethnicity with patient-reported outcome measures (PROMs) at one year after cervical spine surgery., Summary of Background Data: Evidence suggests that Black individuals are 39% to 44% more likely to have postoperative complications and a prolonged length of stay after cervical spine surgery compared with Whites. The long-term recovery assessed with PROMs after cervical spine surgery among Black, Hispanic, and other non-Hispanic groups ( i.e . Asian) remains unclear., Materials and Methods: PROMs were used to assess disability (neck disability index) and neck/arm pain preoperatively and one-year postoperative. Primary outcomes were disability and pain, and not being satisfied from preoperative to 12 months after surgery. Multivariable logistic and proportional odds regression analyses were used to determine the association of racial/ethnic groups [Hispanic, non-Hispanic White (NHW), non-Hispanic Black (NHB), and non-Hispanic Asian (NHA)] with outcomes after covariate adjustment and to compute the odds of each racial/ethnic group achieving a minimal clinically important difference one-year postoperatively., Results: On average, the sample of 14,429 participants had significant reductions in pain and disability, and 87% were satisfied at one-year follow-up. Hispanic and NHB patients had higher odds of not being satisfied (40% and 80%) and having worse pain outcomes (30%-70%) compared with NHW. NHB had 50% higher odds of worse disability scores compared with NHW. NHA reported similar disability and neck pain outcomes compared with NHW., Conclusions: Hispanic and NHB patients had worse patient-reported outcomes one year after cervical spine surgery compared with NHW individuals, even after adjusting for potential confounders, yet there was no difference in disability and neck pain outcomes reported for NHA patients. This study highlights the need to address inherent racial/ethnic disparities in recovery trajectories following cervical spine surgery., Competing Interests: J.S.P. reports personal fees from 3Spine and Steamboat Orthopaedic and Spine Institute.

Study Design: This is a retrospective cohort study., Objective: In patients undergoing elective posterior cervical laminectomy and fusion (PCLF) with a minimum of 5-year follow-up, we sought to compare reoperation rates between patients with an upper instrumented vertebra (UIV) of C2 versus C3/4., Summary of Background Data: The long-term outcomes of choosing between C2 versus C3/4 as the UIV in PCLF remain unclear., Methods: A single-institution, retrospective cohort study from a prospective registry was conducted of patients undergoing elective, degenerative PCLF from December 2010 to June 2018. The primary exposure was UIV of C2 versus C3/4. The primary outcome was reoperation. Multivariable logistic regression controlled for age, smoking, diabetes, and fusion to the thoracic spine., Results: Of the 68 patients who underwent PCLF with 5-year follow-up, 27(39.7%) had a UIV of C2, and 41(60.3%) had a UIV of either C3/4. Groups had similar duration of symptoms (P=0.743), comorbidities (P>0.999), and rates of instrumentation to the thoracic spine (70.4% vs. 53.7%, P=0.210). The C2 group had significantly longer operative time (231.8±65.9 vs. 181.6±44.1 mins, P<0.001) and more fused segments (5.9±1.8 vs. 4.2±0.9, P<0.001). Reoperation rate was lower in the C2 group compared with C3/4 (7.4% vs. 19.5%), though this did not reach statistical significance (P=0.294). Multivariable logistic regression showed increased odds of reoperation for the C3/4 group compared with the C2 group (OR=3.29, 95%CI=0.59-18.11, P=0.170), though statistical significance was not reached. Similarly, the C2 group had a lower rate of instrumentation failure (7.4% vs. 12.2%, P=0.694) and adjacent segment disease/disk herniation (0% vs. 7.3%, P=0.271), though neither trend attained statistical significance., Conclusions: Patients with a UIV of C2 had less than half the number of reoperations and less adjacent segment disease, though neither trend was statistically significant. Despite a lack of statistical significance, whether a clinically meaningful difference exists between UIV of C2 versus C3/4 should be validated in larger samples with long-term follow-up., Level of Evidence: Level-3., Competing Interests: S.L.Z. reports being an unaffiliated neurotrauma consultant for the National Football League.

Background: Spinal anesthesia (SA) is the preferred anesthesia modality for total joint arthroplasty (TJA). However, studies establishing SA as preferential may be subject to selection bias given that general anesthesia (GA) is often selectively utilized on more difficult, higher-risk operations. The optimal comparison group, therefore, is the patient converted to GA due to a failed attempt at SA. The purpose of this study was to determine risk factors and outcomes following failed SA with conversion to GA during primary total hip arthroplasty (THA) or total knee arthroplasty (TKA)., Methods: A consecutive cohort of 4,483 patients who underwent primary TJA at our institution was identified (2,004 THA and 2,479 TKA). Of these patients, 3,307 underwent GA (73.8%), 1,056 underwent SA (23.3%), and 130 patients failed SA with conversion to GA (2.90%). Primary outcomes included rescue analgesia requirement in the postanesthesia care unit (PACU), time to ambulation, pain scores in the PACU, estimated blood loss, and 90-day complications., Results: Risk factors for SA failure included older age and a higher comorbidity burden. Failure of SA was associated with increased estimated blood loss, rescue intravenous opioid use, and time to ambulation when compared to the successful SA group in both THA and TKA patients (P < .001). The anesthesia modality was not associated with significant differences in PACU pain scores. The 90-day complication rate was similar between the failed SA and GA groups. There was a higher incidence of postoperative pain prompting unplanned visits and thromboembolism when comparing failed SA to successful SA in both THA and TKA patients (P < .05)., Conclusions: In our series, patients who had failed SA demonstrated inferior outcomes to patients receiving successful SA and similar outcomes to patients receiving GA who did not have an SA attempt. This emphasizes the importance of success in the initial attempt at SA for optimizing outcomes following TJA., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Study Design: A retrospective cohort study using prospectively collected data., Objective: The aim of this study was to investigate preoperative differences in racial and socioeconomic factors in patients undergoing laminoplasty (LP) versus laminectomy and fusion (LF) for degenerative cervical myelopathy (DCM)., Summary of Background Data: DCM is prevalent in the United States, requiring surgical intervention to prevent neurological degeneration. While LF is utilized more frequently, LP is an emerging alternative. Previous studies have demonstrated similar neurological outcomes for both procedures. However, treatment selection is primarily at the discretion of the surgeon and may be influenced by social determinants of health that impact surgical outcomes., Materials and Methods: The Quality Outcome Database (QOD), a national spine registry, was queried for adult patients who underwent either LP or LF for the management of DCM. Covariates associated with socioeconomic status, pain and disability, and demographic and medical history were collected. Multivariate logistic regression was performed to assess patient factors associated with undergoing LP versus LF., Results: Of 1673 DCM patients, 157 (9.4%) underwent LP and 1516 (90.6%) underwent LF. A significantly greater proportion of LP patients had private insurance (P<0.001), a greater than high school level education (P<0.001), were employed (P<0.001), and underwent primary surgery (P<0.001). LP patients reported significantly lower baseline neck/arm pain and Neck Disability Index (P<0.001). In the multivariate regression model, lower baseline neck pain [odds ratio (OR)=0.915, P=0.001], identifying as non-Caucasian (OR=2.082, P<0.032), being employed (OR=1.592, P=0.023), and having a greater than high school level education (OR=1.845, P<0.001) were associated with undergoing LP rather than LF., Conclusions: In DCM patients undergoing surgery, factors associated with patients undergoing LP versus LF included lower baseline neck pain, non-Caucasian race, higher education, and employment. While symptomatology may influence the decision to choose LP over LF, there may also be socioeconomic factors at play. The trend of more educated and employed patients undergoing LP warrants further investigation., Competing Interests: B.F.S. receives institutional research support from Nuvasive and has previously received institutional support from Stryker Spine.

Background Context: Unplanned readmissions following lumbar spine surgery have immense clinical and financial implications. However, little is known regarding the impact of unplanned readmissions on patient-reported outcomes (PROs) following lumbar spine surgery., Purpose: To evaluate the impact of unplanned readmissions, including specific readmission reasons, on patient reported outcomes 12 months after lumbar spine surgery., Study Design/setting: A retrospective cohort study of prospectively collected data was conducted using patients included in the lumbar module of the Quality and Outcomes Database (QOD), a national, multicenter spine registry., Patient Sample: A total of 33,447 patients who underwent elective lumbar spine surgery for degenerative diseases were included. Mean age was 59.8 (SD=14.04), 53.6% were male, 89.5% were white, 45.9% were employed, and 47.5% had private insurance., Outcome Measures: Unplanned 90-day readmissions and 12-month patient-reported outcomes (PROs) including numeric rating scale (NRS) scores for back and leg pain, Oswestry Disability Index (ODI) scores, EuroQol-5 Dimension (EQ-5D) scores, and North American Spine Society (NASS) patient-satisfaction scores., Methods: The lumbar module of the QOD was queried for adults undergoing elective lumbar spine surgery for degenerative disease. Unplanned 90-day readmissions were classified into 4 groups: medical, surgical, pain-only, and no readmissions. Medical and surgical readmissions were further categorized into primary reason for readmission. 12-month PROs assessing patient back and leg pain (NRS), disability (ODI), quality of life (EQ-5D), and patient satisfaction were collected. Multivariable models predicting 12-month PROs were built controlling for covariates., Results: A total of 31,430 patients (94%) had no unplanned readmission while 2,017 patients (6%) had an unplanned readmission within 90 days following lumbar surgery. Patients with readmissions had significantly worse 12-month PROs compared with those with no unplanned readmissions in covariate-adjusted models. Using Wald-df as a measure of predictor importance, surgical readmissions were associated with the worst 12-month outcomes, followed by pain-only, then medical readmissions. In separate covariate adjusted models, we found that readmissions for pain, SSI/wound dehiscence, and revisions were among the most important predictors of worse outcomes at 12-months., Conclusions: Unplanned 90-day readmissions were associated with worse pain, disability, quality of life, and greater dissatisfaction at 12-months, with surgical readmissions having the greatest impact, followed by pain-only readmissions, then medical readmissions. Readmissions for pain, SSI/wound dehiscence, and revisions were the most important predictors of worse outcomes. These results may help providers better understand the factors that impact outcomes following lumbar spine surgery and promote improved patient counseling and perioperative management., (Copyright © 2023 Elsevier Inc.

Objective: In a cohort of employed patients undergoing elective cervical spine surgery with an uncomplicated postoperative course, the authors sought to determine the demographic, functional, and occupational characteristics associated with return to work (RTW) following surgery., Methods: A retrospective cohort study of prospectively collected data was undertaken of patients undergoing elective cervical spine surgery for degenerative disease in the Quality Outcomes Database. Study inclusion criteria were: 1) employed prior to surgery and planned to RTW, 2) no unplanned readmissions, 3) achieved 30% improvement on the Neck Disability Index (NDI), and 4) were satisfied with the surgical outcome at 3 or 12 months postoperatively. A multivariable Cox regression model was built using demographic, functional, operative, and occupational characteristic to predict time to RTW., Results: Of 5110 included patients, 4788 (93.7%) returned to work within 12 months, with a median time of 35 (IQR 19-60) days. Patients who did RTW were significantly younger (51.3 ± 9.4 vs 55.8 ± 9.6 years, p < 0.001), more often underwent an anterior approach (85.8% vs 80.7%, p = 0.009), were significantly more privately insured (82.1% vs 64.0%, p < 0.001), and were less likely to have workers' disability insurance (6.7% vs 14.6%, p < 0.001) compared with patients who did not RTW. On multivariable Cox regression, demographic factors associated with a longer RTW were older age (hazard ratio [HR] 0.99, 95% CI 0.99-1.00, p < 0.001) and Black race (HR 0.71, 95% CI 0.62-0.81, p < 0.001). Male sex was associated with a shorter RTW time (HR 1.19, 95% CI 1.11-1.26, p < 0.001). Regarding baseline functional status, worse preoperative NDI (HR 0.99, 95% CI 0.99-0.99, p < 0.001) was associated with a longer RTW, whereas the absence of myelopathy was associated with a shorter RTW (HR 1.17, 95% CI 1.09-1.25, p < 0.001). Having a sedentary (HR 1.81, 95% CI 1.65-1.99, p < 0.001), light-intensity (HR 1.60, 95% CI 1.45-1.76, p < 0.001), and medium-intensity (HR 1.11, 95% CI 1.01-1.22, p = 0.037) occupation was associated with a shorter RTW time compared with a heavy-intensity occupation at any time point. Heavy-intensity occupations were independently the strongest predictor of longer RTW. Similar predictors of shorter RTW were found in a subanalysis of occupation intensity and among operative approaches used., Conclusions: Among patients undergoing elective degenerative cervical spine surgery who had favorable surgical outcomes and planned to RTW before surgery, 94% had a successful RTW. Age was the strongest predictor of lower odds of RTW. Regarding time to RTW, having a sedentary, light-intensity, or medium-intensity occupation was associated with a shorter RTW time compared with a heavy-intensity occupation. These findings highlight the importance of considering the demographic and occupational characteristics when predicting postoperative RTW in patients with satisfactory surgical outcomes.

Background and Objectives: Although risk factors for unplanned readmission after cervical spine surgery have been widely reported, less is known about how readmission itself affects patient-reported outcome measures (PROMs). Using the Quality Outcomes Database registry of patients undergoing elective cervical spine surgery, we sought to (1) determine the impact of unplanned readmission on PROMs and (2) compare the effect of specific readmission reasons on PROMs., Methods: An observational study was performed using a multi-institution, retrospective registry for patients undergoing cervical spine surgery. The occurrence of 90-day unplanned readmission classified into medical, surgical, pain only, and no readmissions was the exposure variable. Outcome variables included 12-month PROMs of Neck Disability Index (NDI), Numeric Rating Scale (NRS)-neck/arm pain, EuroQol-5D (EQ-5D), and patient dissatisfaction. Multivariable models predicting each PROM were built using readmission reasons controlling for demographics, clinical characteristics, and preoperative PROMs., Results: Data from 13 355 patients undergoing elective cervical spine surgery (82% anterior approach and 18% posterior approach) were analyzed. Unplanned readmission within 90 days of surgery occurred in 3.8% patients, including medical (1.6%), surgical (1.8%), and pain (0.3%). Besides medical reasons, wound infection/dehiscence was the most common reason for unplanned readmission for the total cohort (0.5%), dysphagia in the anterior approach (0.6%), and wound infection/dehiscence in the posterior approach (1.5%). Based on multivariable regression, surgical readmission was significantly associated with worse 12-month NDI, NRS-neck pain, NRS-arm pain, EQ-5D, and higher odds of dissatisfaction. Pain readmissions were associated with worse 12-month NDI and NRS-neck pain scores, and worse dissatisfaction. For specific readmission reasons, pain, surgical site infection/wound dehiscence, hematoma/seroma, revision surgery, deep vein thrombosis, and pulmonary embolism were significantly associated with worsened 12-month PROMs., Conclusion: In patients undergoing elective cervical spine surgery, 90-day unplanned surgical and pain readmissions were associated with worse 12-month PROMs compared with patients with medical readmissions and no readmissions., (Copyright © Congress of Neurological Surgeons 2024.

Study Design: Retrospective analysis on prospectively collected data., Objectives: To compare posterior lumbar fusions with versus without an interbody in: (1) Patient-reported outcomes (PROs) at 1 year and (2) postoperative complications, readmission, and reoperations., Summary of Background Data: Elective lumbar fusion is commonly used to treat various lumbar pathologies. Two common approaches for open posterior lumbar fusion include posterolateral fusion (PLF) alone without an interbody and with an interbody through techniques, like transforaminal lumbar interbody fusion. Whether fusion with or without an interbody leads to better outcomes remains an area of active research., Patients and Methods: The Lumbar Module of the Quality Outcomes Database was queried for adults undergoing elective primary posterior lumbar fusion with or without an interbody. Covariates included demographic variables, comorbidities, primary spine diagnosis, operative variables, and baseline PROs, including Oswestry Disability Index, North American Spine Society satisfaction index, numeric rating scale-back/leg pain, and Euroqol 5-dimension. Outcomes included complications, reoperations, readmissions, return to work/activities, and PROs. Propensity score matching and linear regression modeling were used to estimate the average treatment effect on the treated to assess the impact of interbody use on patient outcomes., Results: After propensity matching, there were 1044 patients with interbody and 215 patients undergoing PLF. The average treatment effect on the treated analysis showed that having an interbody or not had no significant impact on any outcome of interest, including 30-day complications and reoperations, 3-month readmissions, 12-month return to work, and 12-month PROs., Conclusion: There were no discernible differences in outcomes between patients undergoing PLF alone versus with an interbody in elective posterior lumbar fusion. These results add to the growing body of evidence that posterior lumbar fusions with and without an interbody seem to have similar outcomes up to 1 year postoperatively when treating degenerative lumbar spine conditions., Competing Interests: J.S.P reports a past contract with NeuroPoint Alliance Inc. as well as consulting fees from Steamboat Orthopedic Spine Institute and 3Spine.

Introduction: Anterior cervical discectomy and fusion (ACDF) has proven to be a clinically efficient and cost-effective method for treating patients with degenerative cervical spine conditions. New intervertebral implant products are being developed to improve fusion and stability while decreasing complications. This study assesses the effectiveness of Tritanium C (Tri-C) Anterior Cervical Cage (Stryker) in the treatment of degenerative disk disease (DDD) of the cervical spine compared with polyetheretherketone (PEEK) cages., Methods: A retrospective cohort analysis was conducted using data prospectively collected from two institutions. Patients who underwent ACDFs for DDD using either the Tri-C cage or PEEK cage were identified. The patients' demographics, comorbidities, operative variables, and baseline patient-reported outcomes (PROs) were collected. PROs included the Neck Disability Index (NDI) and numeric rating scale (NRS) for neck and arm pain. The primary outcomes included 3- and 12-month PROs as well as the rates of 90-day readmission, 90-day reoperation, and perioperative complication. The radiographic outcomes included rates of subsidence, cage movement, and successful fusion within 12 months. Multivariate linear regression models were run to identify variables predictive of 12-month PROs., Results: A total of 275 patients who underwent ACDF were included in this study and were divided into two groups: PEEK (n=213) and Tri-C (n=62). Both groups showed improvement in neck and arm pain and NDI postoperatively. When Tri-C and PEEK were compared, no significant differences were observed in the 3- or 12-month changes in neck or arm pain or NDI. Furthermore, there were no differences in the rates of 90-day readmission, 90-day reoperation, and perioperative complication. Regression analysis revealed that Tri-C vs. PEEK was not a significant predictor of any outcome., Conclusions: Our results indicate that the use of porous titanium Tri-C cage during ACDFs is an effective method for managing cervical DDD in terms of PROs, perioperative morbidity, and radiologic parameters. No significant difference was observed in any clinical outcome between patients undergoing ACDF using the Tri-C cage and those in whom the PEEK cage was used., Level of Evidence: III., Competing Interests: Conflicts of Interest: Dr. Stephens reports receiving institutional research support from Nuvasive.

Black American adults often report higher rates of obesity and caregiving compared with other racial or ethnic groups. Consequently, many Black American caregivers and care recipients are obese or have obesity-related chronic conditions (e.g., diabetes, hypertension). This study investigated associations between caregiving and obesity among Black Americans, including the role of health behaviors and chronic conditions. The sample included data from 2015 and 2017 Behavioral Risk Factor Surveillance System for non-Hispanic Black (NHB) or African American adult caregivers ( n = 2,562) and noncaregivers ( n = 7,027). The association between obesity (dependent variable) and caregiving status, fruit consumption, vegetable consumption, physical activity, and number of chronic conditions (independent variables) were evaluated using hierarchical binomial logistic regressions. Caregiving, being female, and chronic conditions were associated with higher odds of obesity, while physical activity was associated with lower odds of obesity. Physical activity, diet, and chronic conditions did not account for differences in obesity among caregiving and noncaregiving Black Americans. Increasing understanding of health behaviors and chronic disease burden of NHB caregivers has implications for programs aiming to improve obesity-related outcomes for caregivers and recipients. Future research should investigate multilevel factors that contribute to observed differences., (© 2024 National Association of Social Workers.)

Objective: The purpose of this study was to examine the feasibility and acceptability of a wearable device and telehealth counseling physical activity intervention early after lumbar spine surgery., Methods: Sixteen patients were randomized to an 8-session physical activity intervention or to usual postoperative care after surgery. The intervention included a wearable device (ie, Fitbit) and telehealth counseling by a licensed physical therapist. The feasibility of study procedures was assessed through recruitment, randomization, retention, and participation rates. Acceptability was assessed through a satisfaction survey and median within-participant change in objective physical activity (steps per day and time spent in moderate-to-vigorous physical activity [MVPA]) and patient-reported outcomes., Results: Of 64 participants who were eligible, recruitment and randomization rates were 41 and 62%, respectively. Retention for objective physical activity and patient-reported outcomes was 94 and 100%, respectively, at 6-month follow-up. Seven (88%) participants in the intervention group completed all telehealth sessions, and 6 (75%) met step goals over the 8 sessions. All participants in the intervention group found the wearable device and telehealth counseling to be helpful and reported it much or somewhat more important than other postoperative services. Median within-participant change for steps per day improved from baseline (preoperative) to 6 months after surgery for both the intervention (1070) and usual care (679) groups, while MVPA only improved for the intervention group (2.2. minutes per day). Improvements in back and leg pain and disability were noted for both groups. No adverse events were reported in the study., Conclusion: Combining wearable technology and telehealth counseling is a feasible approach to promote the physical activity during the early postoperative period after spine surgery. Future randomized controlled trials are needed to investigate the efficacy of leveraging wearables and telehealth during postoperative rehabilitation., Impact: This study has implications for the clinical dissemination of physical activity strategies in the rehabilitation setting., (© The Author(s) 2023.

This study tests the acceptability and feasibility of the first virtual weight loss study individually tailored for middle-aged African American men. Tailor Made is a 3-month randomized controlled pilot of a weight loss intervention that included 58 overweight or obese African American men (mean age of 50.4; SD = 7.9). Control group participants received a Fitbit activity tracker and Bluetooth-enabled scale and copies of the self-led Tailor Made curriculum. Intervention group participants received the same Fitbit, Bluetooth-enabled scale, and curriculum and also participated in weekly, 45-minute virtual small group, professional-led education sessions using the Tailor Made curriculum and received three SMS text messages weekly: (a) a message individually tailored on African American Manhood that links men's values, goals, and motivation to health-promoting behavior; (b) a goal-tracking message to monitor physical activity, healthier eating, and lifestyle changes; and (c) a reminder 24 hours before their session. Participation rates in weekly small group sessions, randomization, and attendance at the assessments suggest that Tailor Made was feasible and acceptable. Only among intervention group participants, we found a small and significant decrease in BMI between baseline and final. In addition, active minutes of physical activity decreased for the control group while active minutes for the intervention group remained steady throughout the intervention. In sum, we demonstrated that a virtual, individually tailored weight loss intervention is feasible and acceptable to African American men. Participants valued the convenience of a virtual intervention, but there were a number of ways we may be able to enhance the potential benefits of this approach.

Grit, a positive psychological trait comprised of perseverance and passion, has been correlated with physician burnout but has not been extensively studied among medical students. Identification of the relationship between grit and burnout as well as between burnout and other demographics could help to identify students at risk of burnout, while informing educational strategies to increase grit in the medical occupation. For this cross-sectional study, an online, email-based survey including demographic questions, the Maslach Burnout Inventory-Human Services (Medical Personnel) Survey, and the Short Grit Scale was distributed to an entire student body of allopathic medical students via a schoolwide listserv in 2019. The response rate was 39.6% (177/444). Negative correlations were displayed between grit and emotional exhaustion, depersonalization, and overall burnout. Positive correlation was demonstrated between grit and personal accomplishment. Male participants had higher depersonalization than female participants and fourth year medical students had higher depersonalization than other years of training. Fourth year medical students had higher personal accomplishment than other years of training and married students had higher personal accomplishment than those who had never been married. These findings are important not only for potential identification of students at risk of burnout, but also for development of strategies to bolster grit and mitigate distressing experiences in the medical occupation. Future studies are necessary to gauge how this relationship may evolve throughout a medical career.

Study Design: Qualitative interview study., Objective: The aim was to develop a conceptual model for Spine Surgery Recovery in order to better understand why patients undergo lumbar spine surgery and what factors influence patient satisfaction., Summary of Background Data: Quantitative studies have assessed patients' expectations for lumbar spine surgery outcomes, with greater expectation fulfillment leading to higher satisfaction. However, there is limited literature using qualitative methods to understand the patient perspective from the decision to undergo lumbar spine surgery through long-term recovery., Materials and Methods: Semistructured phone interviews were conducted with 20 participants (nine females, mean age ±SD=61.2±11.1 yr) and three focus groups with 12 participants (nine females, mean age ±SD=62.0±10.9 yr). Sessions were audio recorded and transcribed. Two independent researchers coded the transcripts using a hierarchical coding system. Major themes were identified and a conceptual model was developed., Results: A total of 1355 coded quotes were analyzed. The decision to have lumbar spine surgery was influenced by chronic pain impact on daily function, pain coping, and patient expectations. Results demonstrated that fulfilled expectations and setting realistic expectations are key factors for patient satisfaction after surgery, while less known constructs of accepting limitations, adjusting expectations, and optimism were found by many patients to be essential for a successful recovery. Emotional factors of fear, anxiety, and depression were important aspects of presurgical and postsurgical experiences., Conclusion: Our Spine Surgery Recovery conceptual model provides guidance for future research and clinical practice to optimize treatment and improve overall patient satisfaction. Recommendations based on this model include the assessment of patient expectations and mental well-being throughout postoperative recovery as well as preoperatively to help set realistic expectations and improve satisfaction. Educational, acceptance-based or positive psychological interventions may be potentially beneficial for addressing key factors identified in this model., Competing Interests: J.S.P. receives consulting fees from 3 Spine and Steamboat Orthopaedic Spine Institute.

Two in five African American men have obesity, but they are underrepresented in community-based weight loss interventions. This pilot effectiveness trial examines the acceptability and feasibility of the first weight loss study for African American men that includes randomization and individual tailoring. Using a community-based, cluster-randomized, longitudinal parallel group design, four churches were randomized to a control condition or a weight loss condition. Each church received physical activity equipment, a coordinator, and small group physical activity sessions. A total of 71 African American men (mean age: 58.5) enrolled and received a Fitbit, Bluetooth-enabled scale, a t-shirt, gift cards for participation, and 45 min of small group physical activity led by a certified personal trainer. Men in the weight loss condition also received 45 min of health education and individually tailored SMS text messages. Multiple metrics suggest that Mighty Men was feasible, yet the acceptability of the intervention components was mixed. Participants in both the weight loss and control conditions lost weight between zero and 6 months ( p < .001), but body fat ( p = .005) and visceral fat percentage ( p = .001) of men in the weight loss condition decreased while men in the control condition did not ( p < .05). An increase in physical activity was seen among men in the weight loss condition ( p = .030) but not among men in the control condition ( p < .05). It is acceptable and feasible to conduct a 6-month weight loss intervention with African American men that includes randomization and individually tailored text messages.

Background: Retired surgeons often have limited opportunities to disseminate their wisdom and expertise in a structured manner to their younger colleagues. In addition, when asked to reflect on their personal and professional lives, many physicians say they wish they had done something differently. The extent to which this is true of retired orthopedic surgeons is not known. Purpose : We sought to determine the percentage of retired orthopedic surgeons who say that they would like to have changed something in their life/career and delineate the most commonly desired changes. Methods : We conducted a cross-sectional study of retired orthopedic surgeons, by emailing a Qualtrics survey to 5864 emeritus members of the American Academy of Orthopaedic Surgeons (AAOS), with 1 initial email invitation in April 2021 followed by 2 reminders in May 2021. The survey employed a branching logic, with up to 16 questions designed to determine whether they would have done anything differently in their life/career. Results : The survey was completed by 1165 of 5864 emeritus AAOS members, for a response rate of nearly 20%. The 3 most represented surgical subspecialties were general orthopedics, adult reconstruction, and hand and upper extremity surgery. Respondents' average age was 74.9 years and age at retirement was 67.8 years; nearly half worked part-time before retiring. More than 80% of the participants said that they had retired at the appropriate time, and 28.5% said they wished they had done something differently. The wished-for changes most often noted were spending more time with family, spending more time on personal wellness, and selecting better practice partners. Conclusion : The results of our survey of retired orthopedic surgeons show that while most were satisfied with their lives and careers, some had regrets. These findings suggest that there may be factors in the work lives of current surgeons that could be altered to reduce regret. Further study is warranted., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Raman spectroscopy (RS) is sensitive to the accumulation of advanced glycation end-products (AGEs), and it measures matrix-sensitive properties that correlate with the fracture toughness of human cortical bone. However, it is unclear whether sugar-mediated accumulation of AGEs affects the fracture toughness of human cortical bone in a manner that is consistent with the negative correlations between amide I sub-peak ratios and fracture toughness. Upon machining 64 single-edge notched beam (SENB) specimens from cadaveric femurs (8 male and 7 female donors between 46 years and 61 years of age), pairs of SENB specimens were incubated in 15 mL of phosphate buffered saline with or without 0.1 M ribose for 4 weeks at 37 °C. After acquiring 10 Raman spectra per bone specimen (n = 32 per incubation group), paired SENB specimens were loaded in three-point bending at a quasi-static or a high loading rate approximating 10 -4 s -1 or 10 -2 s -1 , respectively (n = 16 per incubation group per loading rate). While 2 amide I sub-peak ratios, I 1670 /I 1640 and I 1670 /I 1610 , decreased by 3-5% with a 100% increase in AGE content, as confirmed by fluorescence measurements, the ribose incubation to accumulate AGEs in bone did not affect linear elastic (K Ic ) nor non-linear elastic (K Jc ) measurements of bone's ability to resist crack growth. Moreover, AGE accumulation did not affect the change in these properties when the loading rate changed. Increasing the loading rate increased K Ic but decreased K Jc . Ribose incubation did not affect mineral-related RS properties such as mineral-to-matrix ratios, Type B carbonate substitutions, and crystallinity. It did however increase the thermal stability of demineralized bone (differential scanning calorimetry), without affecting the network connectivity of the organic matrix (i.e., maximum slope during a hydrothermal isometric tension test of demineralized bone). In conclusion, RS is sensitive to AGE accumulation via the amide I band (plus the hydroxyproline-to-proline ratio), but the increase in AGE content due to ribose incubation was not sufficient to affect the fracture toughness of human cortical bone., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Published by Elsevier Ltd.)

Purpose: The modified Japanese Orthopedic Association (mJOA) score consists of six sub-domains and is used to quantify the severity of cervical myelopathy. The current study aimed to assess for predictors of postoperative mJOA sub-domains scores following elective surgical management for patients with cervical myelopathy and develop the first clinical prediction model for 12-month mJOA sub-domain scores.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).

Archer METHODS: A multivariable proportional odds ordinal regression model was developed for patients with cervical myelopathy. The model included patient demographic, clinical, and surgery covariates along with baseline sub-domain scores. The model was internally validated using bootstrap resampling to estimate the likely performance on a new sample of patients., Results: The model identified mJOA baseline sub-domains to be the strongest predictors of 12-month scores, with numbness in legs and ability to walk predicting five of the six mJOA items. Additional covariates predicting three or more items included age, preoperative anxiety/depression, gender, race, employment status, duration of symptoms, smoking status, and radiographic presence of listhesis. Surgical approach, presence of motor deficits, number of surgical levels involved, history of diabetes mellitus, workers' compensation claim, and patient insurance had no impact on 12-month mJOA scores., Conclusion: Our study developed and validated a clinical prediction model for improvement in mJOA scores at 12 months following surgery. The results highlight the importance of assessing preoperative numbness, walking ability, modifiable variables of anxiety/depression, and smoking status. This model has the potential to assist surgeons, patients, and families when considering surgery for cervical myelopathy., Level of Evidence: Level III., (© 2023.

Background: Meniscal and chondral damage is common in the patient undergoing revision anterior cruciate ligament (ACL) reconstruction., Purpose: To determine if meniscal and/or articular cartilage pathology at the time of revision ACL surgery significantly influences a patient's outcome at 6-year follow-up., Study Design: Cohort study; Level of evidence, 3., Methods: Patients undergoing revision ACL reconstruction were prospectively enrolled between 2006 and 2011. Data collection included baseline demographics, surgical technique, pathology, treatment, and scores from 4 validated patient-reported outcome instruments: International Knee Documentation Committee (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Marx Activity Rating Scale. Patients were followed up at 6 years and asked to complete the identical set of outcome instruments. Regression analysis assessed the meniscal and articular cartilage pathology risk factors for clinical outcomes 6 years after revision ACL reconstruction., Results: An overall 1234 patients were enrolled (716 males, 58%; median age, 26 years). Surgeons reported the pathology at the time of revision surgery in the medial meniscus (45%), lateral meniscus (36%), medial femoral condyle (43%), lateral femoral condyle (29%), medial tibial plateau (11%), lateral tibial plateau (17%), patella (30%), and trochlea (21%). Six-year follow-up was obtained on 79% of the sample (980/1234). Meniscal pathology and articular cartilage pathology (medial femoral condyle, lateral femoral condyle, lateral tibial plateau, trochlea, and patella) were significant drivers of poorer patient-reported outcomes at 6 years (IKDC, KOOS, WOMAC, and Marx). The most consistent factors driving outcomes were having a medial meniscal excision (either before or at the time of revision surgery) and patellofemoral articular cartilage pathology. Six-year Marx activity levels were negatively affected by having either a repair/excision of the medial meniscus (odds ratio range, 1.45-1.72; P ≤ .04) or grade 3-4 patellar chondrosis (odds ratio, 1.72; P = .04). Meniscal pathology occurring before the index revision surgery negatively affected scores on all KOOS subscales except for sports/recreation ( P < .05). Articular cartilage pathology significantly impaired all KOOS subscale scores ( P < .05). Lower baseline outcome scores, higher body mass index, being a smoker, and incurring subsequent surgery all significantly increased the odds of reporting poorer clinical outcomes at 6 years., Conclusion: Meniscal and chondral pathology at the time of revision ACL reconstruction has continued significant detrimental effects on patient-reported outcomes at 6 years after revision surgery.

Background: Private insurers use the calendar deductible system, placing pressure on patients and medical personnel to perform medical services before the end of the year to maximize patient savings. The impact of the deductible calendar on patient-reported outcomes (PROs) after spine surgery is poorly understood. The objective of our study was to investigate if patients undergoing surgery in December had different PROs and demographics compared with all other months., Methods: The Quality Outcome Database, a national spine registry, was queried for patients who underwent elective spine surgery between January 2012 and January 2021 for degenerative spine conditions. PROs and demographics were compared between the December and non-December groups using various statistical tests., Results: A total of 978 patients (9.3%) underwent anterior cervical discectomy and fusion in December versus 9548 (90.7%) in other months. There was a significantly higher percentage of patients in December who had private insurance and were employed. A total of 1104 patients (8.5%) underwent lumbar fusion in December versus 11,826 (91.5%) in other months. There was a significantly greater chance of undergoing surgery in December if patients had private insurance and were employed. Although some PROs were statistically significant for the lumbar and cervical cohorts between December and non-December patients, none were clinically significant., Conclusions: Patients undergoing elective spine surgery in December were more likely to have private insurance and be employed. PROs for ACDF and lumbar fusions were not affected by surgical timing (December yes/no). Other spinal procedures directed at more chronic diseases might be more susceptible to external influence of insurance deductibles., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Background Context: Multiple sclerosis (MS) is an autoimmune, neurodegenerative disease that can lead to significant functional disability. Improving treatment regimens have extended life expectancy and led to an increase in the number of elective spine surgeries for degenerative conditions in the MS population. Recent literature has reported mixed results regarding the efficacy of elective spine surgery for patients with MS. There is also a paucity of literature comparing postoperative patient reported outcomes (PROs) and reoperation rates between patients with and without MS., Purpose: To determine if patients with MS have worse PROs and higher complication, readmission and reoperation rates after elective spine surgery compared with patients without neurodegenerative conditions when adjusting for baseline covariates through propensity matching., Study Design/setting: Retrospective review of prospectively collected data from the Quality Outcomes Database (QOD), a national, longitudinal, multicenter spine outcomes registry., Patient Sample: For the lumbar cohort, 312 patients with MS and 46,738 patients without MS were included. The cervical myelopathy cohort included 91 patients with MS and 6,426 patients without MS. The cervical radiculopathy cohort consisted of 103 patients with MS and 13,751 patients without MS., Outcome Measures: 1) complication rates, 2) readmission rates, 3) reoperation rates, and 4) PROs at 3- and 12-months including ODI/NDI, NRS back/neck/arm/leg pain, mJOA scores and patient satisfaction ratings., Methods: Data from the QOD was queried for patients with surgeries occurring between 04/2013-01/2019. Three surgical groups were included: 1) Elective lumbar surgery, 2) Elective cervical surgery for myelopathy, 3) Elective cervical surgery for radiculopathy. Patients with any neurodegenerative condition other than MS were excluded. Patients without MS were propensity matched against patients with MS in a 5 to 1 ratio without replacement based on ASA grade, arthrodesis, surgical approach, number of operated levels, age, and baseline ODI/NDI, NRS leg/arm pain, NRS back/neck pain, and EQ-5D. Multivariable regressions with cluster-robust standard errors were used to estimate average effect of how the outcome would change if the MS patient didn't have the disease. The mean difference was used for continuous outcomes and the risk difference was used for binary outcomes., Results: For the lumbar cohort, no differences were found between the 2 groups at 3 or 12 months in any of the outcome measures. For the myelopathy cohort, patients with MS patients had a lower rate of reoperation at 12 months (risk difference=-0.036, p=.007) and worse 3-month mJOA scores (mean difference=-1.044, p=.004) compared with patients without MS. For the radiculopathy cohort, patients with MS had a lower rate of reoperation at 3 months (risk difference=-0.019, p=.018) and 12 months (risk difference=-0.029, p=.007) compared with those without MS., Conclusions: Patients with MS had similar PROs compared with patients without MS when adjusting for baseline covariates through propensity matching, except for 3-month mJOA scores in the myelopathy cohort. Reoperation rates were found to be lower in patients with MS undergoing elective cervical surgery for both myelopathy and radiculopathy. These results suggest that when analyzed independently, a diagnosis of MS does not significantly impact complication, readmission and reoperation rates or PROs, and therefore should not represent a major contraindication to elective spine surgery. Surgical decisions in this patient population should be made based on careful consideration of patient factors including other comorbidities as well as baseline patient functional status., Competing Interests: Declaration of Competing Interest Dr. Jacquelyn Pennings reports a past contract with NeuroPoint Alliance Inc. as well as consulting fees from Steamboat Orthopaedic Spine Institute and 3Spine.

Study Design: Retrospective review., Objective: The aim was to compare outcomes at 3 and 12 months for patients with lumbar spondylolisthesis treated with direct decompression (DD) versus indirect decompression (ID) techniques., Summary of Background Data: Debate persists regarding the optimal surgical strategy to treat lumbar spondylolisthesis. Novel techniques relying on ID have shown superior radiographic outcomes compared to DD, however, doubt remains regarding their effectiveness in achieving adequate decompression. Currently, there is a paucity of data comparing the clinical efficacy of DD to ID., Methods: The Quality Outcomes Database (QOD), a national, multicenter prospective spine registry, was queried for patients who underwent DD and ID between April 2013 and January 2019. Propensity scores for each treatment were estimated using logistic regression dependent on baseline covariates potentially associated with outcomes. The propensity scores were used to exclude nonsimilar patients. Multivariable regression analysis was performed with the treatment and covariate as independent variables and outcomes as dependent variables., Results: A total of 4163 patients were included in the DD group and 86 in the ID group. The ID group had significantly lower odds of having a longer hospital stay and for achieving 30% improvement in back and leg pain at 3 months. These trends were not statistically significant at 12 months. There were no differences in ED5D scores or Oswestry disability index 30% improvement scores at 3 or 12 months. ID patient had a significantly higher rate of undergoing a repeat operation at 3 months (4.9% vs. 1.5%, P =0.015)., Conclusion: Our study suggests that both DD and ID for the treatment of lumbar spondylolisthesis result in similar clinical outcomes, with the exception that those treated with ID experienced a lower reduction in back and leg pain at 3 months and a higher 3-month reoperation rate. This data can provide surgeons with additional information when counseling patients on the pros and cons of ID versus DD surgery., Competing Interests: Dr J.P. reports a past contract with NeuroPoint Alliance Inc. as well as consulting fees from Steamboat Orthopaedic Spine Institute and 3Spine.

Study Design: Retrospective analysis on prospectively collected data., Objective: To determine the effectiveness of elective spine surgery in patients with Parkinson disease (PD)., Background Context: PD has become increasingly prevalent in an aging population. While surgical treatment for degenerative spine pathology is often required in this population, previous literature has provided mixed results regarding its effectiveness., Methods: Data from the Quality Outcomes Database (QOD) was queried between April 2013 and January 2019. Three surgical groups were identified: (1) elective lumbar surgery, (2) elective cervical surgery for myelopathy, (3) elective cervical surgery for radiculopathy. Patients without PD were propensity matched against patients with PD in a 5:1 ratio without replacement based on American Society of Anesthesiology grade, arthrodesis, surgical approach, number of operated levels, age, and baseline Oswestry Disability Index, Numerical Rating Scale (NRS) extremity pain, NRS back pain, and EuroQol 5-Dimensions (EQ-5D). The mean difference was calculated for continuous outcomes (Oswestry Disability Index, NRS leg pain, NRS back pain, and EQ-5D at 3 and 12 mo after surgery) and the risk difference was calculated for binary outcomes (patient satisfaction, complications, readmission, reoperation, and mortality)., Results: For the lumbar analysis, PD patients had a higher rate of reoperation at 12 months (risk difference=0.057, P =0.015) and lower mean EQ-5D score at 12 months (mean difference=-0.053, P =0.005) when compared with patients without PD. For the cervical myelopathy cohort, PD patients had lower NRS neck pain scores at 3 months (mean difference=-0.829, P =0.005) and lower patient satisfaction at 3 months (risk difference=-0.262, P =0.041) compared with patients without PD. For the cervical radiculopathy cohort, PD patients demonstrated a lower readmission rate at 3 months (risk difference=-0.045, P =0.014) compared with patients without PD., Conclusion: For the matched analysis, in general, patients with and without PD had similar patient-reported outcomes and complication, readmission, and reoperation rates. These results demonstrate that a diagnosis of PD alone should not represent a major contraindication to elective spine surgery., Competing Interests: J.S.P. reports a past contract with NeuroPoint Alliance Inc. as well as consulting fees from Steamboat Orthopaedic Spine Institute and 3Spine.

Study Design: This is a retrospective review of prospectively collected data., Objective: The aim was to evaluate the impact of frailty and sarcopenia on outcomes after lumbar spine surgery., Summary of Background Data: Elderly patients are commonly diagnosed with degenerative spine disease requiring surgical intervention. Frailty and sarcopenia result from age-related decline in physiological reserve and can be associated with complications after elective spine surgery. Little is known about the impact of these factors on patient-reported outcomes (PROs)., Methods: Patients older than 70 years of age undergoing elective lumbar spine surgery were included. The modified 5-item frailty index (mFI-5) was calculated. Sarcopenia was defined using total psoas index, which is obtained by dividing the mid L3 total psoas area by VB area (L3-TPA/VB). PROs included Oswestry disability index (ODI), EuroQual-5D (EQ-5D), numeric rating scale (NRS)-back pain, NRS leg pain (LP), and North American Spine Society (NASS) at postoperative 12 months. Clinical outcomes included length of stay (LOS), 90-day readmission and complications. Univariate and multivariable regression analyses were performed., Results: Total 448 patients were included. The mean mFI-5 index was 1.6±1.0 and mean total psoas index was 1.7±0.5. There was a significant improvement in all PROs from baseline to 12 months ( P <0.0001). After adjusting for age, body mass index, smoking status, levels fused, and baseline PROs, higher mFI-5 index was associated with higher 12-month ODI ( P <0.001), lower 12-month EQ-5D ( P =0.001), higher NRS-L P ( P =0.039), and longer LOS ( P =0.007). Sarcopenia was not associated with 12-month PROs or LOS. Neither sarcopenia or mFI-5 were associated with 90-day complication and readmission., Conclusions: Elderly patients demonstrate significant improvement in PROs after elective lumbar spine surgery. Frailty was associated with worse 12 months postoperative ODI, EQ-5D, NRS-LP scores, and longer hospital stay. While patients with sarcopenia can expect similar outcomes compared with those without, the mFI-5 should be considered preoperatively in counseling patients regarding expectations for disability, health-related quality of life, and leg pain outcomes after elective lumbar spine surgery., Level of Evidence: 3., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Objective: Pain is a common outcome after lower extremity fracture (LEF) requiring surgical fixation. Although psychosocial characteristics have meaningful associations with adverse outcomes, no studies have evaluated how psychosocial characteristics throughout recovery are associated with pain outcomes. The primary purpose of this study was to determine whether psychosocial characteristics are early risk factors for pain outcomes in patients following LEF who have no history of chronic pain., Methods: Participants, 122 patients with a LEF, consented to this single-center, prospective cohort study. Measurements of depression, pain self-efficacy, pain catastrophizing, and fear of movement were completed at 1 week, 6 weeks, 3 months, 6 months, and 12 months after LEF. Chronic pain development and pain intensity were assessed at 12 months. Univariate analyses assessing the difference between means and corresponding effect sizes were evaluated between those individuals with and without chronic pain at 12 months. Separate logistic and linear regression models using psychosocial scores at each time point were used to determine the association with the development of chronic pain and pain intensity, respectively., Results: Of 114 patients (93.4%) who completed the study, 51 (45%) reported chronic pain at 12 months. In the univariate analysis, all psychosocial variables at 6 weeks, 3 months, 6 months, and 12 months were significantly different between those with and those without chronic pain at 12 months (Cohen d range = 0.84 to 1.65). In the multivariate regression models, all psychosocial variables at 6 weeks, 3 months, and 6 months were associated with chronic pain development (odds ratio range = 1.04 to 1.22) and pain intensity (β range = .05 to .14) at 12 months., Conclusion: Psychosocial scores as early as 6 weeks after surgery are associated with pain outcomes 12 months after LEF., Impact: Physical therapists should consider adding psychosocial screening throughout recovery after LEF to identify patients at increased risk for long-term pain outcomes., (© The Author(s) 2022.

Study Design: This was an observational study., Objectives: This study aims to determine the correlation between patient-reported outcomes (PROs) pulled from a national spine registry and physician ratings from physician review websites (PRWs)., Summary of Background Data: PRWs are frequently utilized by patients to make health care decisions; however, many PRWs appear to incorporate subjective experiences unrelated to a surgeon's clinical performance into ratings. As such, their utility as a health care decision-making tool remains unclear., Materials and Methods: This study evaluated 8834 patients from the Quality Outcomes Database (QOD) who underwent 1-level elective lumbar spine surgery. The lumbar module of QOD was queried to rank 124 surgeons using PROs (Oswestry Disability Index, EuroQOL, Numerical Rating Scale-back/leg pain, and patient satisfaction). The QOD PRO-ranking system was compared against PRWs including Healthgrades, Vitals, WebMD, and Google. The Spearman correlation coefficients, Kruskal-Wallis tests, and multiple linear regression models were used for statistical comparison. The primary outcome was the correlation between PRW scores and PROs., Results: Surgeon PRO-derived ranking showed high intercorrelational congruence with coefficients between the 3 PROs (Oswestry Disability Index, EuroQOL, Numerical Rating Scale back/leg) ranging between 0.70 and 0.88. Low correlations were observed between PRO-derived rankings and PRWs, ranging from 0.23 to 0.37. Healthgrades performed most similarly to PRO-derived rankings, correlating best with patient satisfaction, though the correlation was low (ρ=0.37)., Conclusions: While PRWs are often used to evaluate surgeon competency, these results demonstrate they poorly correlate with a surgeon's clinical ability measured by PROs. PRWs should be used with caution when making health care decisions by patients, payers, and administrators., Level of Evidence: Level III., Competing Interests: J.S.P. served as a consultant for 3Spine.

Objective: The purpose of this study was to examine the association between goal attainment and patient-reported outcomes in patients who engaged in a 6-session, telephone-based, cognitive-behavioral-based physical therapy (CBPT) intervention after spine surgery., Methods: In this secondary analysis of a randomized trial, data from 112 participants (mean age = 63.3 [SD = 11.2] years; 57 [51%] women) who attended at least 2 CBPT sessions (median = 6 [range = 2-6]) were examined. At each session, participants set weekly goals and used goal attainment scaling (GAS) to report goal attainment from the previous session. The number and type of goals and percentage of goals met were tracked. An individual GAS t score was computed across sessions. Participants were categorized based on goals met as expected (GAS t score ≥ 50) or goals not met as expected (GAS t score < 50). Six- and 12-month outcomes included disability (Oswestry Disability Index), physical and mental health (12-Item Short-Form Health Survey), physical function (Patient-Reported Outcomes Measurement Information System), pain interference (Patient-Reported Outcomes Measurement Information System), and back and leg pain intensity (numeric rating scale). Outcome differences over time between groups were examined with mixed-effects regression., Results: Participants set a median of 3 goals (range = 1-6) at each session. The most common goal categories were recreational/physical activity (36%), adopting a CBPT strategy (28%), exercising (11%), and performing activities of daily living (11%). Forty-eight participants (43%) met their goals as expected. Participants who met their goals as expected had greater physical function improvement at 6 months (estimate = 3.7; 95% CI = 1.0 to 6.5) and 12 months (estimate = 2.8; 95% CI = 0.04 to 5.6). No other outcome differences were noted., Conclusions: Goal attainment within a CBPT program was associated with 6- and 12-month improvements in postoperative physical functioning., Impact: This study highlights goal attainment as an important rehabilitation component related to physical function recovery after spine surgery., (© The Author(s) 2022.

Three-to-four percent of children with neurofibromatosis type 1 (NF1) present with unilateral tibia bowing, fracture, and recalcitrant healing. Alkaline phosphatase (ALP) enzyme therapy prevented poor bone mineralization and poor mechanical properties in mouse models of NF1 skeletal dysplasia; but transition to clinical trials is hampered by the lack of a technique that (i) identifies NF1 patients at risk of tibia bowing and fracture making them eligible for trial enrollment and (ii) monitors treatment effects on matrix characteristics related to bone strength. Therefore, we assessed the ability of matrix-sensitive techniques to provide characteristics that differentiate between cortical bone from mice characterized by postnatal loss of Nf1 in Osx-cre Tet-Off ;Nf1 flox/flox osteoprogenitors (cKO) and from wild-type (WT) mice. Following euthanasia at two time points of bone disease progression, femur and tibia were harvested from both genotypes (n ≥ 8/age/sex/genotype). A reduction in the mid-diaphysis ultimate force during three-point bending at 20 weeks confirmed deleterious changes in bone induced by Nf1 deficiency, regardless of sex. Pooling females and males, low bound water (BW), and low cortical volumetric bone mineral density (Ct.vBMD) were the most accurate outcomes in distinguishing cKO from WT femurs with accuracy improving with age. Ct.vBMD and the average unloading slope (Avg-US) from cyclic reference point indentation tests were the most sensitive in differentiating WT from cKO tibias. Mineral-to-matrix ratio and carbonate substitution from Raman spectroscopy were not good classifiers. However, when combined with Ct.vBMD and BW (femur), they helped predict bending strength. Nf1 deficiency in osteoprogenitors negatively affected bone microstructure and matrix quality with deficits in properties becoming more pronounced with duration of Nf1 deficiency. Clinically measurable without ionizing radiation, BW and Avg-US are sensitive to deleterious changes in bone matrix in a preclinical model of NF1 bone dysplasia and require further clinical investigation as potential indicators of an onset of bone weakness in children with NF1. © 2022 American Society for Bone and Mineral Research (ASBMR)., (© 2022 American Society for Bone and Mineral Research (ASBMR).)

Study Design: Retrospective analysis on prospectively collected data., Objective: The aim of this study was to construct a clinical prediction model for 90-day mortality in elderly patients with traumatic spine injuries., Summary of Background Data: Spine trauma in the elderly population is increasing. Comparing elderly spine trauma patients to younger patients with similar injuries proves challenging due to the extensive comorbidities and frailty found in the elderly. There is a paucity of evidence to predict survival of elderly patients following traumatic spinal injuries., Methods: All patients 65+ with spine trauma presenting to a level I trauma center from 2010 to 2019 were reviewed from a prospectively maintained trauma registry. Retrospective chart review was performed to record injury, frailty scores, comorbidities, presence of spinal cord injury, imaging evidence of sarcopenia and osteopenia, mortality, and complications. We preselected 13 variables for our multivariable logistic regression model: hypotension on admission, gender, marital status, age, max Abbreviated Injury Scale, Modified Frailty Index, surgical treatment, hematocrit, white blood count, spinal cord injury, closed head injury, injury level and presence of high energy mechanism. The performance of the prediction model was evaluated using a concordance index and calibration plot. The model was internally validated via bootstrap approach., Results: Over the 9-year period, 1746 patients met inclusion criteria; 359 (20.6%) patients died within 90 days after presenting with spine trauma. The most important predictors for 90-day mortality were age, hypotension, closed head injury, max Abbreviated Injury Scale and hematocrit. There was an optimism-corrected C-index of 0.77. A calculator was created to predict a personalized mortality risk., Conclusion: The incidence of spine trauma in elderly patients continues to increase. Previous publications described preexisting conditions that imply increased mortality, but ours is the first to develop a predictive calculator. Prospective research is planned to externally validate this model to better determine its predictive value and utility in the clinical setting., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background Context: Diabetes mellitus (DM) is a well-established risk factor for suboptimal outcomes following cervical spine surgery. Hemoglobin A1C (HbA1c), a surrogate for long-term glycemic control, is a valuable assessment tool in diabetic patients., Purpose: In patients undergoing elective cervical spine surgery, we sought to identify optimal HbA1c levels to: (1) maximize 1-year postoperative patient-reported outcomes (PROs), and (2) predict the occurrence of medical and surgical complications., Study Design/setting: A retrospective cohort study using prospectively collected data was performed in a single academic center., Patient Sample: Diabetic patients undergoing elective anterior cervical fusion and posterior cervical laminectomy and fusion (PCLF) between October 2010-March 2021 were included., Outcome Measures: Primary outcomes included Numeric Rating Scale (NRS)-Neck pain, NRS-Arm pain, and Neck Disability Index (NDI). Secondary outcomes included surgical site infection (SSI), complications, readmissions, and reoperations within 90-days postoperatively., Methods: HbA1c, demographic, comorbidity, and perioperative variables were gathered in diabetic patients only. PROs were analyzed as continuous variables and minimum clinically difference (MCID) was set at 30% improvement from baseline., Results: Of 1992 registry patients undergoing cervical surgery, 408 diabetic patients underwent cervical fusion surgery. Anterior: A total of 259 diabetic patients underwent anterior cervical fusion, 141 of which had an available HbA1c level within one year prior to surgery. Mean age was 55.8±10.1, and mean HbA1c value was 7.2±1.4. HbA1c levels above 6.1 were associated with failure to achieve MCID for NDI (AUC=0.77, 95%CI 0.70-0.84, p<.001), and HbA1c levels above 6.8 may be associated with increased odds of reoperation (AUC=0.61, 95%CI 0.52-0.69, p=.078). Posterior: A total of 149 diabetic patients underwent PCLF, 65 of which had an available HbA1c level within 1 year. Mean age was 63.6±9.2, and mean HbA1c value was 7.2±1.5. Despite a low AUC for NRS-Arm pain and readmission, HbA1c levels above 6.8 may be associated with failure to achieve MCID for NRS-Arm pain (AUC=0.61, 95%CI 0.49-0.73, p=.094), and HbA1c levels above 7.6 may be associated with higher readmission rate (AUC=0.63, 95%CI 0.50-0.75, p=.185)., Conclusions: In a cohort of diabetic patients undergoing elective cervical spine surgery, HbA1c levels above 6.1 were associated with decreased odds of achieving MCID for NDI in anterior cervical fusion surgery. Though only moderate associations were seen for the select outcomes of reoperation (6.8), readmission (7.6), and MCID for NRS-Arm pain (6.8), preoperative optimization of HbA1c using these levels as benchmarks should be considered to reduce the risk of complications and maximize PROs for patients undergoing elective cervical spine surgery., (Copyright © 2022 Elsevier Inc.

Background: Lytic or malpositioned tunnels may require bone grafting during revision anterior cruciate ligament reconstruction (rACLR) surgery. Patient characteristics and effects of grafting on outcomes after rACLR are not well described., Purpose: To describe preoperative characteristics, intraoperative findings, and 2-year outcomes for patients with rACLR undergoing bone grafting procedures compared with patients with rACLR without grafting., Study Design: Cohort study; Level of evidence, 3., Methods: A total of 1234 patients who underwent rACLR were prospectively enrolled between 2006 and 2011. Baseline revision and 2-year characteristics, surgical technique, pathology, treatment, and patient-reported outcome instruments (International Knee Documentation Committee [IKDC], Knee injury and Osteoarthritis Outcome Score [KOOS], Western Ontario and McMaster Universities Osteoarthritis Index, and Marx Activity Rating Scale [Marx]) were collected, as well as subsequent surgery information, if applicable. The chi-square and analysis of variance tests were used to compare group characteristics., Results: A total of 159 patients (13%) underwent tunnel grafting-64 (5%) patients underwent 1-stage and 95 (8%) underwent 2-stage grafting. Grafting was isolated to the femur in 31 (2.5%) patients, the tibia in 40 (3%) patients, and combined in 88 patients (7%). Baseline KOOS Quality of Life (QoL) and Marx activity scores were significantly lower in the 2-stage group compared with the no bone grafting group ( P ≤ .001). Patients who required 2-stage grafting had more previous ACLRs ( P < .001) and were less likely to have received a bone-patellar tendon-bone or a soft tissue autograft at primary ACLR procedure ( P ≤ .021) compared with the no bone grafting group. For current rACLR, patients undergoing either 1-stage or 2-stage bone grafting were more likely to receive a bone-patellar tendon-bone allograft ( P ≤ .008) and less likely to receive a soft tissue autograft ( P ≤ .003) compared with the no bone grafting group. At 2-year follow-up of 1052 (85%) patients, we found inferior outcomes in the 2-stage bone grafting group (IKDC score = 68; KOOS QoL score = 44; KOOS Sport/Recreation score = 65; and Marx activity score = 3) compared with the no bone grafting group (IKDC score = 77; KOOS QoL score = 63; KOOS Sport/Recreation score = 75; and Marx activity score = 7) ( P ≤ .01). The 1-stage bone graft group did not significantly differ compared with the no bone grafting group., Conclusion: Tunnel bone grafting was performed in 13% of our rACLR cohort, with 8% undergoing 2-stage surgery. Patients treated with 2-stage grafting had inferior baseline and 2-year patient-reported outcomes and activity levels compared with patients not undergoing bone grafting. Patients treated with 1-stage grafting had similar baseline and 2-year patient-reported outcomes and activity levels compared with patients not undergoing bone grafting.

Study Design: This was a single-institution, retrospective cohort study., Objective: We aimed to develop a predictive model for proximal junctional kyphosis (PJK) severity that considers multiple preoperative variables and modifiable surgical alignment., Summary of Background Data: PJK is a common complication following adult deformity surgery. Current alignment targets account for age and pelvic incidence but not other risk factors., Materials and Methods: This is a single-institution, retrospective cohort study of adult deformity patients with a minimum 2-year follow-up undergoing instrumented fusion between 2009 and 2018. A proportional odds regression model was fit to estimate PJK probability and Hart-International Spine Study Group (ISSG) PJK severity score. Predictors included preoperative Charlson Comorbidity Index, vertebral Hounsfield Units near the upper instrumented vertebrae, pelvic incidence, T1-pelvic angle, and postoperative L1-L4 and L4-S1 lordosis. Predictor effects were assessed using adjusted odds ratios and a nomogram constructed for estimating PJK probability. Bootstrap resampling was used for internal validation., Results: Of 145 patients, 47 (32%) developed PJK. The median PJK severity score was 6 (interquartile range, 4-7.5). After adjusting for predictors, Charlson Comorbidity Index, Hounsfield Units, preoperative T1-pelvic angle, and postoperative L1-L4 and L4-S1 lordosis were significantly associated with PJK severity ( P <0.05). After adjusting for potential overfitting, the model showed acceptable discrimination [ C -statistic (area under the curve)=0.75] and accuracy (Brier score=0.10)., Conclusions: We developed a model to predict PJK probability, adjusted for preoperative alignment, comorbidity burden, vertebral bone density, and modifiable postoperative L1-L4 and L4-S1 lordosis. This approach may help surgeons assess the patient-specific risk of developing PJK and provide a framework for future predictive models assessing PJK risk after adult deformity surgery., Level of Evidence: Level III., Competing Interests: B.F.S. has previously received consulting fees from Stryker and Depuy-Synthes.

Background: The Subjective Patient Outcome for Return to Sports (SPORTS) score is a single-item scale that measures athletes' ability to return to their preinjury sport based on effort and performance., Purpose/hypothesis: The purpose of this study was to examine the psychometric properties of the SPORTS score and a modified score within the first year after anterior cruciate ligament reconstruction (ACLR). The modified version replaced "same sport" with "any sport" in the answer choices. It was hypothesized that both versions of the SPORTS score would have acceptable floor and ceiling effects and internal responsiveness, moderate convergent validity, and excellent test-retest reliability., Study Design: Cohort study (diagnosis); Level of evidence, 2., Methods: Patients were recruited preoperatively from 2 academic medical centers. The authors collected responses to the 1-item SPORTS scores at 6 and 12 months after ACLR and the Tegner activity scale, Lysholm knee score, Knee injury and Osteoarthritis Outcome Score (KOOS)-sport/recreation subscale, and Marx activity rating scale preoperatively and 6 and 12 months after ACLR. Ceiling and floor effects and responsiveness were assessed using descriptive statistics and cross-tabulations, respectively, at both follow-up time points. Spearman correlations and intraclass correlation coefficients were used to examine convergent validity and test-retest reliability, respectively., Results: Follow-up rates at 6 and 12 months were 100% and 99%, respectively. Test-retest follow-up was 77%. Floor effects for the SPORTS scores were not observed, while ceiling effects at 12 months ranged from 38% to 40%. Cross-tabulation of the SPORTS scores showed that 64% to 66% of patients reported a change in their score from 6 to 12 months, with significant differences noted between the proportions that improved versus worsened for return to any sport. Convergent validity was observed at 6 and 12 months via moderate correlations with the Tegner, Lysholm, KOOS-sport/recreation, and Marx scores ( r = 0.31 to 0.47). Fair to good test-retest reliability (intraclass correlation coefficient, 0.58 and 0.60) was found at 12 months after ACLR., Conclusion: The SPORTS score appears to be a reliable, responsive, and valid 1-item scale that can be used during the first year after ACLR. No differences in psychometric properties were found between the SPORTS score and the modified version., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: This study was funded by an American Orthopaedic Society for Sport Medicine/Aircast Foundation Return to Play Grant.

Background: With increased reliance on digital health care, including telehealth, efficient and effective ways are needed to assess patients' comfort and confidence with using these services., Objective: The goal of this study was to develop and validate a brief scale that assesses digital health care literacy., Methods: We first developed an item pool using existing literature and expert review. We then administered the items to participants as part of a larger study. Participants were caregivers of children receiving care at a pediatric clinic who completed a survey either on the web or over the telephone. We randomized participants into development and confirmatory samples, stratifying by language so that exploratory factor analysis and confirmatory factor analysis could be performed with separate samples of participants. We assessed the scale's validity by examining its associations with participants' demographics, digital access, and prior digital health care use., Results: Participants (N=508) were, on average, aged 34.7 (SD 7.7) years, and 89.4% (454/508) were women. Of the 508 participants, 280 (55.1%) preferred English as their primary language, 157 (30.9%) preferred Spanish, and 71 (14%) preferred Arabic; 228 (45%) had a high school degree or less; and 230 (45.3%) had an annual household income of

Introduction: Surgical management of degenerative lumbar spine disorders is effective at improving patient pain, disability, and quality of life; however, obtaining a durable posterolateral fusion after decompression remains a challenge. Interbody fusion technologies are viable means of improving fusion rates in the lumbar spine, specifically various graft materials including autograft, structural allograft, titanium, and polyether ether ketone. This study assesses the effectiveness of Tritanium posterolateral cage in the treatment of degenerative disk disease., Methods: Nearest-neighbor 1:1 matched control transforaminal lumbar interbody fusion with PEEK vs. Tritanium posterior lumbar (PL) cage interbody fusion patients were identified using propensity scoring from patients that underwent elective surgery for degenerative disk diseases. Line graphs were generated to compare the trajectories of improvement in patient-reported outcomes (PROs) from baseline to 3 and 12 months postoperatively. The nominal data were compared via the χ 2 test, while the continuous data were compared via Student's t-test., Results: The two groups had no difference regarding either the 3- or 12-month Euro-Qol-5D (EQ-5D), numeric rating scale (NRS) leg pain, and NRS back pain; however, the Tritanium interbody cage group had better Oswestry Disability Index (ODI) scores compared to the control group of the PEEK interbody cage at both 3 and 12 months (p=0.013 and 0.048)., Conclusions: Our results indicate the Tritanium cage is an effective alternative to the previously used PEEK cage in terms of PROs, surgical safety, and radiological parameters of surgical success. The Tritanium cohort showed better ODI scores, higher fusion rates, lower subsidence, and lower indirect costs associated with surgical management, when compared to the propensity-matched PEEK cohort., Competing Interests: Conflicts of Interest: Financial support and industry affiliations: Dr. Devin reports a Stryker grant, Stryker consulting, Wright medical, defense expert witness, and Medtronic legal consulting outside the submitted work.

Objective: To synthesize evidence on physical activity interventions that used wearables, either alone or in combination with education or rehabilitation, in adults following orthopaedic surgical procedures., Methods: PubMed, CINAHL, PsycINFO and EMBASE were searched for randomized controlled trials of wearable-based interventions from each database's inception to August 2021 in patients undergoing orthopaedic surgery. Relevant outcomes included physical activity, physical function, pain, psychological distress, or general health. PEDro scale scoring ranges from 0 to 10 and was used to appraise studies as high (≥7), moderate (5-6), or poor (<5) quality., Results: Of 335 articles identified, 6 articles met eligibility criteria. PEDro scores ranged from 2 to 6, with 3 studies of moderate quality and 3 of poor quality. Studies included patients undergoing total knee (number; n = 4) or total knee or hip (n = 1) arthroplasty and lumbar disc herniation surgery (n = 1). In addition to wearables, intervention components included step diary (n = 2), motivational interviewing (n = 1), goal setting (n = 2), tailored exercise program (n = 2), or financial incentives (n = 1). Interventions were delivered in-person (n = 2), remotely (n = 3) or in a hybrid format (n = 1). Intervention duration ranged from 6 weeks to 6 months. Compared to controls, 3 moderate quality studies reported greater improvement in steps/day; however, 1 moderate and 2 poor quality studies showed no between-group difference in physical function, pain, or quality of life. No serious adverse events related to the use of wearable were reported., Conclusions: The effects of physical activity interventions using wearables, either delivered in-person or remotely, appear promising for increasing steps per day after joint arthroplasty; however, this finding should be viewed with caution since it is based on 3 moderate quality studies. Further research is needed to determine the therapeutic effects of using wearables as an intervention component in patients undergoing other orthopaedic surgical procedures., Trial Registration: PROSPERO Registration Number: CRD42020186103., Competing Interests: The authors have declared that no competing interests exist.

Abstract: Vitamin D is important in musculoskeletal health, and low serum vitamin D concentration is common in athletes. This study implemented a vitamin D screening and supplementation protocol in a cohort of National Collegiate Athletic Association Division I athletes using summer 25-hydroxyvitamin D concentration and a seasonal variation calculator to achieve sufficient vitamin D concentration year-round. After implementation of the Vitamin D Protocol, there was a nonsignificant difference in athletes with sufficient winter vitamin D concentrations (72.6%) compared with summer vitamin D concentrations (66.1%) (P = 0.40). The Seasonal Variation Calculator predicted winter vitamin D concentrations (8 ± 18 ng·mL-1) higher than actual winter vitamin D concentrations (P < 0.01). While most athletes (78%) believed vitamin D was important for athletic performance, athlete compliance to the Vitamin D Protocol was inconsistent. In the future, adjustment of vitamin D screening and supplementation protocols may help athletes achieve sufficient vitamin D status year-round., (Copyright © 2022 by the American College of Sports Medicine.)

Background: Grit has been defined as "perseverance and passion for long-term goals" and is characterized by maintaining focus and motivation toward a challenging ambition despite setbacks. There are limited data on the impact of grit on burnout and psychologic well-being in orthopaedic surgery, as well as on which factors may be associated with these variables., Questions/purposes: (1) Is grit inversely correlated with burnout in orthopaedic resident and faculty physicians? (2) Is grit positively correlated with psychologic well-being in orthopaedic resident and faculty physicians? (3) Which demographic characteristics are associated with grit in orthopaedic resident and faculty physicians? (4) Which demographic characteristics are associated with burnout and psychologic well-being in orthopaedic resident and faculty physicians?, Methods: This study was an institutional review board-approved interim analysis from the first year of a 5-year longitudinal study of grit, burnout, and psychologic well-being in order to assess baseline relationships between these variables before analyzing how they may change over time. Orthopaedic residents, fellows, and faculty from 14 academic medical centers were enrolled, and 30% (335 of 1129) responded. We analyzed for the potential of response bias and found no important differences between sites in low versus high response rates, nor between early and late responders. Participants completed an email-based survey consisting of the Duckworth Short Grit Scale, Maslach Burnout Inventory-Human Services (Medical Personnel) Survey, and Dupuy Psychological Well-being Index. The Short Grit Scale has been validated with regard to internal consistency, consensual and predictive validity, and test-retest stability. The Psychological Well-being Index has similarly been validated with regard to reliability, test-retest stability, and internal consistency, and the Maslach Burnout Inventory has been validated with regard to internal consistency, reliability, test-retest stability, and convergent validity. The survey also obtained basic demographic information such as survey participants' age, gender, race, ethnicity, marital status, current year of training or year in practice (as applicable), and region of practice. The studied population consisted of 166 faculty, 150 residents, and 19 fellows. Beyond the expected age differences between sub-populations, the fellow population had a higher proportion of women than the faculty and resident populations did. Pearson correlations and standardized β coefficients were used to assess the relationships of grit, burnout, psychologic well-being, and continuous participant characteristics., Results: We found moderate, negative relationships between grit and emotional exhaustion (r = -0.30; 95% CI -0.38 to -0.21; p < 0.001), depersonalization (r = -0.34; 95% CI -0.44 to -0.23; p < 0.001), and the overall burnout score (r = -0.39; 95% CI -0.48 to -0.31; p < 0.001). The results also showed a positive correlation between grit and personal accomplishment (r = 0.39; 95% CI 0.29 to 0.48; p < 0.001). We also found a moderate, positive relationship between grit and psychologic well-being (r = 0.39; 95% CI 0.30 to 0.49; p < 0.001). Orthopaedic surgeons with 21 years or more of practice had higher grit scores than physicians with 10 to 20 years of practice. Orthopaedic surgeons in practice for 21 years or more also had lower burnout scores than those in practice for 10 to 20 years. Married physicians had higher psychologic well-being than unmarried physicians did., Conclusion: Among orthopaedic residents, fellows, and faculty, grit is inversely related to burnout, with lower scores for emotional exhaustion and depersonalization and higher scores for personal accomplishment as grit increases., Clinical Relevance: The results suggest that grit could be targeted as an intervention for reducing burnout and promoting psychologic well-being among orthopaedic surgeons. Other research has suggested that grit is influenced by internal characteristics, life experiences, and the external environment, suggesting that there is potential to increase one's grit. Residency programs and faculty development initiatives might consider measuring grit to assess for the risk of burnout, as well as offering curricula or training to promote this psychologic characteristic., Competing Interests: This study received funding from NCATS/NIH (award number UL1TR000445).

Background: The purpose of this study was to investigate the longitudinal postoperative relationship between physical activity, psychosocial factors, and physical function in patients undergoing lumbar spine surgery., Methods: We enrolled 248 participants undergoing surgery for a degenerative lumbar spine condition. Physical activity was measured using a triaxial accelerometer (Actigraph GT3X) at 6-weeks (6wk), 6-months (6M), 12-months (12M) and 24-months (24M) following spine surgery. Physical function (computerized adaptive test domain version of Patient-Reported Outcomes Measurement Information System) and psychosocial factors (pain self-efficacy, depression and fear of movement) were assessed at preoperative visit and 6wk, 6M, 12M and 24M after surgery. Structural equation modeling (SEM) techniques were utilized to analyze data, and results are represented as standardized regression weights (SRW). Overall SRW were computed across five imputed datasets to account for missing data. The mediation effect of each psychosocial factor on the effect of physical activity on physical function were computed [(SRW for effect of activity on psychosocial factor X SRW for effect of psychosocial factor on function) ÷ SRW for effect of activity on function]. Each SEM model was tested for model fit by assessing established fit indexes., Results: The overall effect of steps per day on physical function (SRW ranged from 0.08 to 0.19, p<0.05) was stronger compared to the overall effect of physical function on steps per day (SRW ranged from non-existent to 0.14, p<0.01 to 0.3). The effect of steps per day on physical function and function on steps per day remained consistent after accounting for psychosocial factors in each of the mediation models. Depression and fear of movement at 6M mediated 3.4% and 5.4% of the effect of steps per day at 6wk on physical function at 12M, respectively. Pain self-efficacy was not a statistically significant mediator., Conclusions: The findings of this study suggest that the relationship between physical activity and physical function is stronger than the relationship of function to activity. However, future research is needed to examine whether promoting physical activity during the early postoperative period may result in improvement of long-term physical function. Since depression and fear of movement had a very small mediating effect, additional work is needed to investigate other potential mediating factors such as pain catastrophizing, resilience and exercise self-efficacy., (© 2021.

Objective: To investigate whether early postoperative walking is associated with "best outcome" and no opioid use at 1 year after lumbar spine surgery and establish a threshold for steps/day to inform clinical practice., Design: Secondary analysis from randomized controlled trial., Setting: Two academic medical centers in the United States., Participants: We enrolled 248 participants undergoing surgery for a degenerative lumbar spine condition (N=248). A total of 212 participants (mean age, 62.8±11.4y, 53.3% female) had valid walking data at baseline., Interventions: Not applicable., Main Outcome Measures: Disability (Oswestry Disability Index), back and leg pain (Brief Pain Inventory), and opioid use (yes vs no) were assessed at baseline and 1 year after surgery. "Best outcome" was defined as Oswestry Disability Index ≤20, back pain ≤2, and leg pain ≤2. Steps/day (walking) was assessed with an accelerometer worn for at least 3 days and 10 h/d at 6 weeks after spine surgery, which was considered as study baseline. Separate multivariable logistic regression analyses were conducted to determine the association between steps/day at 6 weeks and "best outcome" and no opioid use at 1-year. Receiver operating characteristic curves identified a steps/day threshold for achieving outcomes., Results: Each additional 1000 steps/d at 6 weeks after spine surgery was associated with 41% higher odds of achieving "best outcome" (95% confidence interval [CI], 1.15-1.74) and 38% higher odds of no opioid use (95% CI, 1.09-1.76) at 1 year. Walking ≥3500 steps/d was associated with 3.75 times the odds (95% CI, 1.56-9.02) of achieving "best outcome" and 2.37 times the odds (95% CI, 1.07-5.24) of not using opioids., Conclusions: Walking early after surgery may optimize patient-reported outcomes after lumbar spine surgery. A 3500 steps/d threshold may serve as an initial recommendation during early postoperative counseling., (Copyright © 2021 The American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

Objective : To describe the safety, feasibility, and preliminary outcomes of an early telephone-supported home exercise program (HEP) performed within the first 6 weeks after anterior cervical discectomy and fusion (ACDF) surgery. Methods : Eight patients (mean ± SD age = 53.4 ± 14.9 years, 5 females) were enrolled in this case series. Immediately after surgery, patients began a 6-week HEP including daily walking, deep breathing, distraction techniques, and cervical and upper body exercises. The HEP was supported by weekly telephone calls by a physical therapist. Safety for performing early exercise was examined with radiographic imaging at 6 months. Adverse events were assessed through weekly calls with a physical therapist. HEP adherence and acceptability data were obtained by patient self-report. Clinical measures were assessed preoperatively, at 6 weeks and at 6 months, and included the Neck Disability Index, Numeric Rating Scale for pain, Tampa Scale of Kinesiophobia, Pain Catastrophizing Scale, Pain Self-Efficacy Questionnaire, and accelerometry for physical activity. Results : Early radiographic imaging showed no signs of nonunion at 6 months. There were no reports of serious adverse events. At 6 months, all patients reported clinically significant changes in pain catastrophizing. Seven (88%) patients had clinically significant changes in disability and arm pain, six (75%) patients for neck pain and pain self-efficacy, and five (53%) patients for fear of movement. Only three (43%) of seven patients showed increased physical activity at 6 months. Conclusion : Based on this small case series, an early telephone-supported HEP appears safe for patients, feasible to implement, and promising for clinical benefits.

Objective: Neurosurgeons generate an enormous amount of data daily. Within these data lie rigorous, valid, and reproducible evidence. Such evidence can facilitate healthcare reform and improve quality of care. To measure the quality of care provided objectively, evaluating the safety and efficacy of clinical activities should occur in real time. Registries must be constructed and collected data analyzed with the precision akin to that of randomized clinical trials to accomplish this goal., Methods: The Quality Outcomes Database (QOD) Tumor Registry was launched in February 2019 with 8 sites in its initial 1-year pilot phase. The Tumor Registry was proposed by the AANS/CNS Tumor Section and approved by the QOD Scientific Committee in the fall of 2018. The initial pilot phase aimed to assess the feasibility of collecting outcomes data from 8 academic practices across the United States; these outcomes included length of stay, discharge disposition, and inpatient complications., Results: As of November 2019, 923 eligible patients have been entered, with the following subsets: intracranial metastasis (17.3%, n = 160), high-grade glioma (18.5%, n = 171), low-grade glioma (6%, n = 55), meningioma (20%, n = 184), pituitary tumor (14.3%, n = 132), and other intracranial tumor (24%, n = 221)., Conclusions: The authors have demonstrated here, as a pilot study, the feasibility of documenting demographic, clinical, operative, and patient-reported outcome characteristics longitudinally for 6 common intracranial tumor types.

Background: Although graft choice may be limited in the revision setting based on previously used grafts, most surgeons believe that graft choice for anterior cruciate ligament (ACL) reconstruction is an important factor related to outcome., Hypothesis: In the ACL revision setting, there would be no difference between autograft and allograft in rerupture rate and patient-reported outcomes (PROs) at 6-year follow-up., Study Design: Cohort study; Level of evidence, 2., Methods: Patients who had revision surgery were identified and prospectively enrolled in this cohort study by 83 surgeons over 52 sites. Data collected included baseline characteristics, surgical technique and pathology, and a series of validated PRO measures. Patients were followed up at 6 years and asked to complete the identical set of PRO instruments. Incidence of additional surgery and reoperation because of graft failure were also recorded. Multivariable regression models were used to determine the predictors (risk factors) of PROs, graft rerupture, and reoperation at 6 years after revision surgery., Results: A total of 1234 patients including 716 (58%) men were enrolled. A total of 325 (26%) underwent revision using a bone-patellar tendon-bone (BTB) autograft; 251 (20%), soft tissue autograft; 289 (23%), BTB allograft; 302 (25%), soft tissue allograft; and 67 (5%), other graft. Questionnaires and telephone follow-up for subsequent surgery information were obtained for 809 (66%) patients, while telephone follow-up was only obtained for an additional 128 patients for the total follow-up on 949 (77%) patients. Graft choice was a significant predictor of 6-year Marx Activity Rating Scale scores ( P = .024). Specifically, patients who received a BTB autograft for revision reconstruction had higher activity levels than did patients who received a BTB allograft (odds ratio [OR], 1.92; 95% CI, 1.25-2.94). Graft rerupture was reported in 5.8% (55/949) of patients by their 6-year follow-up: 3.5% (16/455) of patients with autografts and 8.4% (37/441) of patients with allografts. Use of a BTB autograft for revision resulted in patients being 4.2 times less likely to sustain a subsequent graft rupture than if a BTB allograft were utilized ( P = .011; 95% CI, 1.56-11.27). No significant differences were found in graft rerupture rates between BTB autograft and soft tissue autografts ( P = .87) or between BTB autografts and soft tissue allografts ( P = .36). Use of an autograft was found to be a significant predictor of having fewer reoperations within 6 years compared with using an allograft ( P = .010; OR, 0.56; 95% CI, 0.36-0.87)., Conclusion: BTB and soft tissue autografts had a decreased risk in graft rerupture compared with BTB allografts. BTB autografts were associated with higher activity level than were BTB allografts at 6 years after revision reconstruction. Surgeons and patients should consider this information when choosing a graft for revision ACL reconstruction.
