We present the technique of biologic tuberoplasty, where an acellular dermal allograft is used to cover the tuberosity in patients with massive irreparable cuff tears to prevent bone-to-bone contact between the tuberosity and acromion when active elevation is attempted. This technique can be performed in patients with massive rotator cuff tears who are low-demand and have significant medical comorbidities, poor bone quality, or who are not candidates for a reverse shoulder arthroplasty or who cannot tolerate a lengthy rehabilitation protocol. It is less time-consuming than a superior capsule reconstruction and more bone-sparing than traditional tuberoplasty. Patients with massive rotator cuff tears involving the supraspinatus and a portion of the infraspinatus lose their force couple, leading to superior humeral head migration with abutment of the tuberosity against the acromion upon deltoid activation. The center of rotation moves superiorly with deltoid contraction, developing an acromiohumeral articulation. This results in bone-to-bone contact between the acromion and humerus, leading to pain and acetabularization of the acromion over time. Coverage of the tuberosity with the acellular dermal allograft acts as an interpositional tissue and prevents bone-to-bone contact between the tuberosity and acromion., Technique Video Video 1 The procedure is demonstrated on a right shoulder with the patient in the lateral decubitus position. A burr is used to remove any osteophytes or hypertrophy of the tuberosity until a bleeding cancellous surface is achieved. The length of the tuberosity is measured at 30 mm and the width at 20 mm. An ArthroFlex that is 3 mm thick is then measured to these dimensions and cut to size. Three puncture holes are made and also punched to widen them in the medial and the lateral edges of the graft for easier passage of FiberTape sutures. Knotless SwiveLocks are then placed in the anteromedial, posteromedial, and central aspect of the tuberosity footprint. A 10-cc syringe with the end cut off is used to allow for easier passage of the graft. The FiberTapes, repair stitch, and loop stitch are then retrieved through the syringe from each anchor, leaving behind the pull stitch from each anchor. The sutures from each anchor are kept separated and clamped to the syringe for suture management. The repair stitch from each anchor is then passed in a mattress fashion from the edge of the graft and is then passed through the loop of the loop stitch and folded over. The pull stitch from that anchor is then pulled, bringing the repair stitch into the knotless mechanism and locking it in like a finger trap so it cannot back out. This is performed for each anchor. The mattress stitches will be used to pull the graft into the shoulder. The FiberTapes from each anchor are then passed through the pre-punched holes. The FiberTapes are then passed back through the lateral edge of the graft in an expanded speedbridge configuration. This will allow better control of the graft when lateral row anchors are placed for fixation and will eliminate dog ears in the graft. The pull sutures from each anchor are then sequentially pulled, allowing the mattress passes to shorten and thus reducing the graft into the shoulder. The graft can be seen entering the subacromial space. The pull stitches are pulled until the graft is secured to the medial edge of the footprint. Although there appears to be disorganization of sutures, when the FiberTape limbs are pulled individually, the slack is taken out of them and the graft and sutures become more manageable. The posteromedial corner of the graft is grasped and reduced to that corner and the pull stitch is pulled one last time to tighten it and secure the graft to that corner. The same step is repeated for the anteromedial corner followed by the central pull stitch. The posteromedial FiberTapes are then retrieved from a posterolateral cannula and passed into the SwiveLock anchor to fixate the graft. The steps are then repeated for the anterolateral FiberTapes and then followed by the central FiberTapes. The graft will prevent bone to bone contact between the acromion and tuberosity.

Background Opioids are commonly prescribed for postoperative pain following total joint arthroplasty. Despite widespread use, few studies have examined the dose-dependent effect of perioperative opioid use on postoperative complications following total hip arthroplasty (THA) and total knee arthroplasty (TKA). Therefore, we examined the dose-dependent relationship between opioid use and postoperative complications following primary THA and TKA. Methods We queried the Premier Healthcare Database to identify adult patients who underwent primary elective THA or TKA from 2004 to 2014, and quantified opioid consumption within the first 3 postoperative days. Opioid consumption was standardized to morphine milligram equivalents (MMEs). Patients were divided into quintiles on the basis of MME exposure: 172 MMEs. Primary outcomes included postoperative periprosthetic joint infection, pulmonary embolism, deep venous thrombosis, and pulmonary complications. Secondary outcomes included wound infection, wound dehiscence, and readmission within 30 and 90 days postoperatively. Univariate and multivariate analyses were performed to compare differences between groups and to account for confounders. Results A total of 1,525,985 patients were identified. The mean age was 65.7 ± 10.8 years, 598,320 patients (39.2%) were male, and 1,174,314 patients (77.0%) were Caucasian. On multiple logistic regression analysis, increasing MME exposure was associated with a dose-dependent increased risk of postoperative complications. Compared with patients receiving 172 MMEs was associated with greater odds of periprosthetic joint infection (adjusted odds ratio [aOR], 1.37; 95% confidence interval [CI], 1.33 to 1.42), deep venous thromboembolism (aOR, 1.34; 95% CI, 1.30 to 1.38), pulmonary embolism (aOR, 1.29; 95% CI, 1.25 to 1.34), and pulmonary complications (aOR, 1.06; 95% CI, 1.05 to 1.08). Exposure to >172 MMEs was associated with increased risk of wound infection (aOR, 1.37; 95% CI, 1.33 to 1.41), wound dehiscence (aOR, 1.24; 95% CI, 1.19 to 1.31), and readmission within 30 (aOR, 1.21; 95% CI, 1.20 to 1.22) and 90 days (aOR, 1.20; 95% CI, 1.19 to 1.21). Conclusions Increasing opioid use within the early postoperative period following THA or TKA was associated with a dose-dependent increased risk of periprosthetic joint infection and venous thromboembolic events.

STUDY DESIGN This is a retrospective cohort study of consecutive patients undergoing lumbar spinal fusion (LSF) within the PearlDiver Humana research database from 2010 to 2018. OBJECTIVE The aim of this study was to determine if timing of total hip arthroplasty (THA) affects LSF outcomes. SUMMARY OF BACKGROUND DATA In patients with both spine and hip pathology, outcomes of THA have been shown to be affected by the timing of THA relative to LSF. However, few studies have assessed postoperative outcomes following LSF in this clinical scenario. MATERIALS AND METHODS A national database was queried for patients undergoing lumbar fusion and divided into 4 groups: (1) those who underwent LSF without THA (No THA); (2) those who underwent THA at least 2 years before LSF (>2 Prior THA); (3) those who underwent THA in the 2 years before LSF (0-2 Prior THA); and (4) those who underwent THA after LSF (THA After). We assessed lumbar-specific outcomes, including pseudarthrosis, revision, mechanical failure, and adjacent segment disease (ASD); as well as systemic complications. Controlling for age, sex, and Charlson comorbidity index, complication rates between all groups were assessed using univariate and multivariate logistic regression analysis. Post hoc comparisons were performed using the Fisher exact test with Bonferroni correction to account for multiple pairwise comparisons, resulting in an adjusted threshold for statistical significance of P

Background and Aims: There are approximately 1 million total knee arthroplasty (TKA) and total hip arthroplasty (THA) procedures performed annually in the United States. With this number projected to increase, it is vital for orthopedic surgeons and health-care systems to properly anticipate healthcare utilization related to TKA and THA. Google Trends (GT) is a free, open source tool that provides customizable analysis of search terms entered into the Google search engine. We aim to explore the relationship between public interest in TKA and THA as determined by GT data and volume of TKA and THA procedures. Methods: GT data were compiled for ten search terms related to TKA and ten search terms related to THA from January 2009 to December 2017. Annual case volumes for TKA/THA procedures were obtained from the Healthcare Cost and Utilization Project National Inpatient Sample from 2009 to 2017. Trend analysis was performed using univariate linear regression of GT data and TKA/THA case volumes. Results: There was a statistically significant positive correlation between GT data and procedure volume for 14 of the 20 search terms studied. Seven TKA-related search terms with a positive correlation to procedure volumes include “total knee replacement,” “knee replacement,” “knee osteoarthritis,” “knee ache,” “knee swelling,” “knee stiffness,” and “chronic knee pain.” Seven THA-related search terms with a positive correlation to procedure volumes include “hip arthroplasty,” “total hip replacement,” “hip replacement,” “hip osteoarthritis,” “hip ache,” “hip swelling,” and “chronic hip pain.” Conclusion: GT may provide a high utility as a convenient and informative data set for orthopedic surgeons to analyze public interest in TKA and THA procedures. The data provided by GT have the potential to provide real-time, actionable information that may help surgeons and health systems to characterize public interest in TKA and THA and to best identify and address patient needs. Relevance for Patients: The GT tool can be used to measure public interest in TKA/THA, which can inform physician expectations for the patient encounter and lead to the creation of decision aids that better inform the public about the risks and benefits of TKA/THA.

STUDY DESIGN Retrospective database analysis. OBJECTIVE To identify nationwide temporal trends in management of geriatric odontoid fractures and to compare comorbidities, inpatient complications, hospital characteristics, and cost between patients receiving operative versus nonoperative management. SUMMARY OF BACKGROUND DATA The treatment of geriatric odontoid fractures remains controversial with some studies demonstrating decreased mortality and improved functional outcomes associated with operative management and significant morbidity associated with halo devices during nonoperative management. METHODS Patients between ages 65 to 90 years with odontoid fractures who underwent operative or nonoperative management between the years 2003 and 2017 were identified in the National Inpatient Sample (NIS) database. Year of injury, demographic variables, comorbidities, inpatient complications, mortality, length of stay, inpatient cost, and hospital characteristics were compared between operative and nonoperative treatment groups. RESULTS Thirty two thousand four hundred nineteen patients (average age 77 yr, 54% female) were included in the final analysis. Operative treatment occurred in 21,954 (67%) patients and nonoperative treatment occurred in 10,465 (32%). In 2003, operative treatment occurred in 46% of patients and nearly doubled to 86% in 2017, with an average increase of 3.7% per year (P

Background No consensus exists regarding postoperative splinting position following volar plate fixation of distal radius fractures. Purpose The purpose of this study was to determine whether immobilization in supination would result in superior outcomes compared with no restriction of forearm range of motion. Patients and Methods All patients >18 years of age with distal radius fractures indicated for volar plate fixation were eligible. Exclusion criteria were open fracture and concomitant injury to, or functional deficit of, either upper extremity. Patients were randomized to immobilization in (1) maximal supination with a sugar-tong splint or (2) no restriction of supination with a volar splint. Patient-Rated Wrist Evaluation (PRWE), Disabilities of the Arm, Shoulder, and Hand (DASH) score, and visual analog scale (VAS) score; wrist range of motion; and grip strength were recorded at 2 and 6 weeks postoperatively. A Student's t-test was used to compare mean values of all outcome measures at each time point. Results A total of 46 patients enrolled in the study; 28 were immobilized with a volar splint and 18 were immobilized with a sugar-tong splint. Six-week follow-up data were obtained for 32 patients. There was no significant difference in PRWE, DASH, and VAS scores; or range of motion; or grip strength between the two groups postoperatively. Conclusion Range of motion, grip strength, and patient-rated outcome measures were similar regardless of postoperative immobilization technique in patients with a distal radius fractures stabilized with a volar plate. Surgeons can elect to use the standard-of-care postoperative immobilization modality of their preference following volar plate fixation without compromising short-term return to function. Level of Evidence This is a Level II, therapeutic study.

Background: Traumatic upper extremity amputation in a child can be a life-altering injury, yet little is known about the epidemiology or health care costs of these injuries. In this study, using the Healthcare Cost and Utilization Project (HCUP) Kids’ Inpatient Database (KID), we assess these trends to learn about the risk factors and health care costs of these injuries. Methods: Using the HCUP KID from 1997 to 2012, patients aged 20 years old or younger with upper extremity traumatic amputations were identified. National estimates of incidence, demographics, costs, hospital factors, patient factors, and mechanisms of injury were assessed. Results: Between 1997 and 2012, 6130 cases of traumatic upper extremity amputation occurred in children. This resulted in a $166 million cost to the health care system. Males are 3.4 times more likely to be affected by amputation than females. The most common age group to suffer amputation is in older children, aged 15 to 19 years old. The frequency of amputation has declined 41% from 1997 to 2012. The overwhelming majority of amputations (92.54%) involved digits. Conclusions: Pediatric traumatic amputations of the upper extremity are a significant contribution to health care spending. Interventions and educational campaigns can be targeted based on national trends to prevent these costly injuries.

Category: Ankle, Trauma, Mental Health Introduction/Purpose: Recognizing psychological risk factors for developing Complex Regional Pain Syndrome (CRPS) may facilitate the diagnosis of CRPS and can be critical in its prevention and treatment. The purpose of this study was to evaluate the association between psychological dysfunction and developing CRPS after sustaining an ankle fracture. Methods: The PearlDiver patient record database was used to identify patients who sustained an ankle fracture between 2005 and 2015. These patients were screened for development of CRPS based on the presence or absence of psychological disorders including anxiety disorder, bipolar disorder, delirium, psychosis, depression, chronic pain syndrome, and fibromyalgia. A substratification analysis was performed assessing the additional risk of developing CRPS by undergoing operative versus nonoperative management. Results: 163,529 patients were identified who sustained an ankle fracture and CRPS was identified in 10,127 (6.2%) of these patients. The risk of developing CRPS after sustaining an ankle fracture was significantly elevated with an OR of 5.44 (PConclusion: Patients with a known psychological disorder were five times more likely to develop CRPS after sustaining an ankle fracture. There was no additional risk due to operative management. This information may be useful in the diagnosis and treatment of patients with mental health disorders who sustain an ankle fracture and subsequently develop CRPS.

Neonatal brachial plexus palsy (NBPP) is a birth injury that can cause severe functional loss in the affected limb. The purpose of this study was to determine the temporal changes in the national incidence of this condition and whether associated risk factors have changed over time. Children born via vaginal delivery were identified in the Kids' Inpatient Database (KID) from 1997 to 2012, and those with NBPP were identified. The trend in incidence and risk factors were assessed through the study period. The nationwide incidence of NBPP decreased during the study period. Infants with shoulder dystocia, fetal macrosomia, and gestational diabetes had the highest risk of developing NBPP, while multiple birth mates during delivery had a protective effect. Multiple risk factors, including shoulder dystocia, macrosomia, and heavy for dates became less predictive of the development of NBPP over time. Several risk factors predispose children to the development of NBPP, and the effect of these risk factors has been changing. This information can guide obstetric treatment to help prevent NBPP. Level of evidence is diagnostic, level 3.

STUDY DESIGN Retrospective database analysis. OBJECTIVE The aim of this study was to match risk factors for complications in patients who did and did not sustain a dural tear while undergoing posterior lumbar spine surgery and compare local and systemic complications. SUMMARY OF BACKGROUND DATA Current data do not adequately define whether the event of sustaining an isolated dural tear increases the risk for postoperative complications while controlling for other confounding risk factors. METHODS The PearlDiver Database was queried for patients who underwent posterior lumbar spine decompression and/or fusion for degenerative pathology. Patients with and without dural tears were 1:2 matched based on demographic variables and comorbidities. Complications, cost, length of stay (LOS), and readmission rates were analyzed. RESULTS The 1:2 matched cohort included 9038 patients with a dural tear and 17,340 patients without a dural tear. All complications assessed were significantly higher in the dural tear group (P
