Introduction: Delay in surgical management for orthopaedic emergencies and severe fracture types can result in notable morbidity and even mortality for patients. Disparities in various facets of orthopaedic care have been identified based on race/ethnicity, socioeconomic status, and payer status, but disparities in time to surgery have been poorly explored. The purpose of this study was, therefore, to investigate whether disparities exist in time to emergent orthopaedic surgery., Methods: Patients who underwent surgery for hip fracture, femur fracture, pelvic fracture, septic knee, septic hip, or cauda equina syndrome over 2012 to 2020 were identified using national data. Multivariable linear regression models were constructed, controlling for age, sex, race/ethnicity, payer status, socioeconomic status, hospital setting, and comorbidities to examine the effect of payer status and race/ethnicity, on time to surgery., Results: Over 2012 to 2020, 247,370 patients underwent surgery for hip fracture, 64,827 for femur fracture, 14,130 for pelvic fracture, 14,979 for septic knee, 3,205 for septic hip, and 4,730 for cauda equina syndrome. On multivariable analysis, patients with Medicaid experienced significantly longer time to surgery for hip fracture, femur fracture, pelvic fracture, septic knee, and cauda equina syndrome ( P < 0.05 all). Black patients experienced longer time to surgery for hip fracture, femur fracture, septic knee, septic hip, and cauda equina syndrome, and Hispanic patients experienced longer time to surgery for hip fracture, femur fracture, pelvic fracture, and cauda equina syndrome ( P < 0.05 all)., Discussion: The results of this study demonstrate that Medicaid-insured patients, and often minority patients, experience longer delays to surgery than privately insured and White patients. Future work should endeavor to identify causes of these disparities to promote creation of policies aimed at improving timely access to care for Medicaid-insured and minority patients., Level of Evidence: III., (Copyright © 2024 by the American Academy of Orthopaedic Surgeons.)

Study Design: Retrospective review., Objectives: We substratified the mFI-5 frailty index to reflect controlled and uncontrolled conditions and assess their relationship to perioperative complications., Summary of Background Data: Risk assessment before adult spinal deformity (ASD) surgery is critical because the surgery is highly invasive with a high complication rate. Although frailty is associated with risk of surgical complications, current frailty measures do not differentiate between controlled and uncontrolled conditions., Methods: Frailty was calculated using the mFI-5 index for 170 ASD patients with fusion of ≥5 levels. Uncontrolled frailty was defined as blood pressure >140/90 mm Hg, HbA1C >7% or postprandial glucose >180 mg/dL, or recent chronic obstructive pulmonary disease (COPD) exacerbation, while on medication. Patients were divided into nonfrailty, controlled frailty, and uncontrolled frailty cohorts. The primary outcome measure was perioperative major and wound complications. Bivariate analysis was performed. Multivariable analysis assessed the relationship between frailty and perioperative complications., Results: The cohorts included 97 nonfrail, 54 controlled frail, and 19 uncontrolled frail patients. Compared with nonfrail patients, patients with uncontrolled frailty were more likely to have age older than 60 years (84% vs. 24%), hyperlipidemia (42% vs. 20%), and Oswestry Disability Index (ODI) score >42 (84% vs. 52%) ( P <0.05 for all). Controlled frailty was associated with those older than 60 years (41% vs. 24%) and hyperlipidemia (52% vs. 20%) ( P <0.05 for all). On multivariable regression analysis controlling for hyperlipidemia, functional independence, motor weakness, ODI>42, and age older than 60 years, patients with uncontrolled frailty had greater odds of major complications (OR 4.24, P =0.03) and wound complications (OR 9.47, P =0.046) compared with nonfrail patients. Controlled frailty was not associated with increased risk of perioperative complications ( P >0.05 for all)., Conclusions: Although patients with uncontrolled frailty had higher risk of perioperative complications compared with nonfrail patients, patients with controlled frailty did not, suggesting the importance of controlling modifiable risk factors before surgery., Level of Evidence: 3., Competing Interests: Dr. Kebaish reports consultant fees and other support from DePuy Synthes and Stryker, as well as support from Orthofix and SpineCraft.

Study Design: Retrospective review., Objective: To determine whether the Activity Measure for Post-Acute Care (AM-PAC) "6-Clicks" score is associated with the development of postoperative ileus., Summary of Background Data: Adult spinal deformity (ASD) surgery has a high complication rate. One common complication is postoperative ileus, and poor postoperative mobility has been implicated as a modifiable risk factor for this condition., Methods: Eighty-five ASD surgeries in which ≥5 levels were fused were identified in a single institution database. A physical therapist/physiatrist collected patients' daily postoperative AM-PAC scores, for which we assessed first, last, and daily changes. We used multivariable linear regression to determine the marginal effect of ileus on continuous AM-PAC scores; threshold linear regression with Bayesian information criterion to identify a threshold AM-PAC score associated with ileus; and multivariable logistic regression to determine the utility of the score thresholds when controlling for confounding variables., Results: Ten of 85 patients (12%) developed ileus. The mean day of developing ileus was postoperative day 3.3±2.35. The mean first and last AM-PAC scores were 16 and 18, respectively. On bivariate analysis, the mean first AM-PAC score was lower in patients with ileus than in those without (13 vs. 16; P< 0.01). Ileus was associated with a first AM-PAC score of 3 points lower (Coef. -2.96; P< 0.01) than that of patients without ileus. Patients with an AM-PAC score<13 had 8 times greater odds of developing ileus ( P= 0.023). Neither the last AM-PAC score nor the daily change in AM-PAC score was associated with ileus., Conclusions: In our institutional cohort, a first AM-PAC score of <13, corresponding to an inability to walk or stand for more than 1 minute, was associated with the development of ileus. Early identification of patients who cannot walk or stand after surgery can help determine which patients would benefit from prophylactic management., Level of Evidence: Level-III., Competing Interests: B.J.N. reports grants/research support from DePuy Synthes and is on the speaker’s bureau for Medtronic.

Introduction: Data regarding racial/ethnic and socioeconomic differences in revision total hip arthroplasty (rTHA) and revision total knee arthroplasty (rTKA) have been inconsistent. This study examined racial/ethnic and socioeconomic disparities in comorbidity-adjusted risk and reason for rTHA and rTKA., Methods: Patients who underwent rTHA or rTKA between 2006 and 2014 in the National Inpatient Sample were identified. Multivariable logistic regression models adjusted for payer status, hospital geographic setting, and patient characteristics (age, sex, and Elixhauser Comorbidity Index) were used to examine the effect of race/ethnicity and socioeconomic status on trends in annual risk of rTHA/rTKA and causes of rTHA/rTKA., Results: Black patients were less likely to undergo rTHA and more likely to undergo rTKA while Hispanic patients were more likely to undergo rTHA and less likely to undergo rTKA ( P < 0.001 for all) compared with White patients. Patients residing in areas of lower income quartiles were more likely to undergo rTHA and rTKA compared with those in the highest quartile ( P < 0.001), and these disparities persisted and widened over time. Black, Hispanic, and Asian patients were less likely to undergo rTHA/rTKA because of dislocation compared with White patients ( P < 0.001 for all). Patients from areas of lower income quartiles were more likely to undergo rTHA because of septic complications and less likely to require both rTHA and rTKA because of mechanical complications ( P < 0.001 for all)., Discussion: Racial/ethnic and socioeconomic disparities exist in risk and cause of rTHA and rTKA. Increasing awareness and a focus on minimizing variability in hospital quality may help mitigate these disparities., (Copyright © 2023 by the American Academy of Orthopaedic Surgeons.)

Background: Mental health conditions affect tens of millions of Americans. In recent years, particularly with the advent of the coronavirus disease 2019 pandemic, there has been a burst of interest in mental health and mental illness among orthopaedic surgical patients. The mental health of orthopaedic surgeons themselves has also come into focus, with high reported rates of burnout and depression. The aim of this article was to evaluate trends in publication on mental health and mental illness in orthopaedic surgery., Methods: Web of Science and PubMed were queried to conduct a systematic review. Studies that discussed orthopaedic surgery and mental illnesses or mental health topics over 2001 to 2022 were included. Publications were analyzed by article-, author-, and topic-level characteristics., Results: A total of 416 studies were analyzed after application of inclusion and exclusion criteria. Publication volume increased dramatically, demonstrating quadratic growth over 2001 to 2022 (p < 0.001). Eighty-eight percent of studies focused on patients and 10% on surgeons, with studies about patients more likely to focus on mental illness and those about surgeons more likely to focus on mental health (p < 0.001). Twenty percent of publications had a female senior author, and 5 authors collectively accounted for 10% of all publications. Eight journals published more than 10 publications, accounting for 35% of all publications. The most productive subspecialties were arthroplasty (135, 30%), general orthopaedics (87, 21%), and spine (69, 17%). Mental illnesses that were least represented included schizophrenia, bipolar disorder, eating disorders, attention-deficit/hyperactivity disorder, and personality disorders (1% or less of total publications each)., Conclusion: This analysis showed a dramatically increasing trend in publications on mental health and mental illness in orthopaedic surgery. A high concentration of publications came from a subset of journals and senior authors, and women were overrepresented as senior authors relative to their representation in the field. The results of this analysis identified gaps in the literature, including underrepresented subspecialties, understudied mental illnesses, and study of orthopaedic surgeon mental health, and thus highlighted areas for future investigation., Level of Evidence: Therapeutic Level IV.

Case: We present the case of an 81-year-old woman who developed profound hypercalcemia requiring admission to the intensive care unit after calcium sulfate bead use during revision hip arthroplasty. The patient's serum calcium level peaked at 21.0 mg/dL and was associated with acute encephalopathy. After treatment with calcitonin and bisphosphonates, her serum calcium level normalized and her mentation improved., Conclusion: The risk of clinically significant hypercalcemia should be considered when using calcium sulfate during orthopaedic surgery., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/B823)., (Copyright © 2022 by The Journal of Bone and Joint Surgery, Incorporated.)
