RESUMO
BACKGROUND: In accordance with the high incidence of bilateral knee osteoarthritis, many patients have undergone bilateral total knee arthroplasty (BTKA). Whether patients undergo bilateral procedures in a staged or simultaneous fashion, the physical and mental burden of undergoing 2 major orthopedic procedures is considerable. The aims of this study were to (1) investigate differences between minimal clinically important difference (MCID) achievement between staged versus simultaneous BTKA, and (2) identify the patient variables, specifically mental scores, that were associated with MCID achievement in patients undergoing BTKA. METHODS: Simultaneous and staged BTKA patients within a single health care network from 2016 to 2021 were retrospectively reviewed. Patient demographics, surgery details, and Patient-Reported Outcome Measurement Information System Physical Function Short Forms 10a (PROMIS PF10a), PROMIS Mental scores, and Knee Disability Osteoarthritis Outcome Scores (KOOS) were reviewed. Preoperative and postoperative patient-reported outcome measures were collected before the first total knee arthroplasty (TKA) and after the second TKA, respectively, in staged BTKA patients. The final cohort consisted of 249 patients, with an average age of 66 years (range, 21 to 87), 63% women, and an average body mass index of 32 (range, 20 to 52), at a mean follow-up of 1.1 years (range, 0.5 to 2.4). Multivariate regressions were performed on MCID PF10a and KOOS achievement, as well as whether the BTKA was performed simultaneously versus staged. RESULTS: A preoperative PROMIS Mental score in the upper 2 quartiles was associated with MCID PF10a achievement in BTKA. Men and surgeries performed at an Academic Medical Center were negatively associated with the achievement of MCID KOOS. Interestingly, those who underwent simultaneous BTKA were less likely to achieve MCID KOOS than those who underwent a staged BTKA. CONCLUSIONS: Preoperative mental robustness may be positively associated with improved physical function outcome in BTKA patients.
RESUMO
OBJECTIVE: Para athletes reap significant health benefits from sport but are vulnerable to non-accidental harms. Little is known about the types and impacts of non-accidental harms Para athletes face. In this literature review, we summarise current knowledge and suggest priorities for future research related to non-accidental harms in Para athletes. DESIGN: Six electronic databases were searched between August and September 2017. 2245 articles were identified in the initial title/abstract review, and 202 records were selected for full-text review following preliminary screening. Two independent examiners evaluated each full text, and eight citations were selected based on inclusion/exclusion criteria. DATA SOURCES: MEDLINE, Embase, PsycInfo, Cumulative Index to Nursing and Allied Health Literature, Scopus and Academic Search Premier. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Inclusion criteria: (A) human participants; (B) written in English; (C) descriptive, cohort and case series, case-control, qualitative, mixed methods studies and all clinical trials; and (D) data pertain to harassment/abuse of youth, recreational, collegiate, national-level and/or elite-level athletes with a physical and/or intellectual impairment. RESULTS: Most studies focused on young, visually impaired athletes and approximately half of all studies described high rates of bullying and its social implications. One study confirmed remarkably high rates of psychological, physical and sexual harms in Para athletes, compared with able-bodied peers. CONCLUSIONS: Bullying in young, visually impaired athletes is described most commonly in the available literature. Due to the limited amount of data, the prevalence of non-accidental harms in Para athletes remains unclear and information on trends over time is similarly unavailable.

BACKGROUND: Geriatric femoral neck fracture is a common injury for which hemiarthroplasty (HA) or total hip arthroplasty (THA) may be considered in select patients. As prior database studies comparing these have not used propensity matching, which is a robust statistical method of controlling for potentially confounding variables, unmatched and matched methodologies are contrasted in the present study. METHODS: Patients aged ≥70 years who underwent HA or THA for hip fractures were identified from the 2012-2015 National Surgical Quality Improvement database. Propensity score 1:1 matching was performed. Differences in rates of 30-day postoperative adverse outcomes were compared using multivariate logistic regression for unmatched and matched cohorts. RESULTS: In total, 15,558 patients (14,403 HA and 1155 THA) were evaluated. Although multivariate outcomes for the unmatched populations were different for blood transfusion, mortality, minor adverse events, major adverse events, and reoperation, multivariate outcomes for matched populations only differed for blood transfusion (odds ratio 0.6 for HA vs THA, P < .001). Of note, although readmissions were similar for the two groups, patients undergoing THA had a 5.4% greater rate of perioperative readmission due to dislocation. CONCLUSION: Geriatric patients undergoing HA and THA for hip fracture were compared with and without propensity matching. Once matching was performed, the only differences in outcomes between the two groups were a lower transfusion rate among the HA group and a greater readmission rate due to dislocation among the THA group. This suggests that either procedure can be safely considered if found to be advantageous from a longer-term outcome perspective. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

OBJECTIVES: To determine whether racial/ethnic disparities in 30/90/180-day mortality, major morbidity, and unplanned readmissions exist among universally insured older adult (≥65 years) emergency general surgery patients; vary by diagnostic category; and can be explained by variations in geography, teaching status, age-cohort, and a hospital's percentage of minority patients. SUMMARY OF BACKGROUND DATA: As the US population ages and discussions surrounding the optimal method of insurance provision increasingly enter into national debate, longer-term outcomes are of paramount concern. It remains unclear the extent to which insurance changes disparities throughout patients' postacute recovery period among older adults. METHODS: Survival analysis of 2008 to 2014 Medicare data using risk-adjusted Cox proportional-hazards models. RESULTS: A total of 6,779,649 older adults were included, of whom 82.8% identified as non-Hispanic white (NHW), 9.2% non-Hispanic black (NHB), 5.6% Hispanic, and 1.5% non-Hispanic Asian (NHA). Relative to NHW patients, each group of minority patients was significantly less likely to die [30-day NHB vs NHW hazard ratio (95% confidence interval): 0.88 (0.86-0.89)]. Differences became less apparent as outcomes approached 180 days [180-day NHB vs NHW: 1.00 (0.98-1.02)]. For major morbidity and unplanned readmission, differences among NHW, Hispanic, and NHA patients were comparable. NHB patients did consistently worse. Efforts to explain the occurrence found similar trends across diagnostic categories, but significant differences in disparities attributable to geography and the other included factors that combined accounted for up to 50% of readmission differences between racial/ethnic groups. CONCLUSION: The study found an inversion of racial/ethnic mortality differences and mitigation of non-NHB morbidity/readmission differences among universally insured older adults that decreased with time. Persistent disparities among nonagenarian patients and hospitals managing a regionally large share of minority patients warrant particular concern.

BACKGROUND: While deaths, hospitalizations, and emergency department visits for head trauma are well understood, little is known about presentations in outpatient settings. Our objective was to examine the epidemiology and extent of healthcare-seeking adult (18-64 years) head trauma patients presenting in outpatient settings compared with patients receiving nonhospitalized emergency department care. METHODS: We used 2004-2013 MarketScan Medicaid/commercial claims to identify head trauma patients managed in outpatient settings (primary care provider, urgent care) and the emergency department. We examined differences in demographic and injury-specific factors, Centers for Disease Control and Prevention-defined head trauma diagnoses, and extent of and reasons for postindex visit ambulatory care use within 30/90/180 days by index visit location, as well as annual and monthly variations in head trauma trends. We used outpatient incidence rates to estimate the US nationwide outpatient burden. RESULTS: A total of 1.19 million index outpatient visits were included (emergency department: 348,659). Nationwide, they represented a weighted annual burden of 1.16 million index outpatient cases. These encompassed 46% of all known healthcare-seeking head trauma in 2013 (outpatient/emergency department/inpatient/fatalities) and increased in magnitude (+31%) from 2004 to 2013. One fourth (27%) of office/clinic visits led to diagnosis with concussion on index presentation (urgent care: 32%). Distributions of demographic factors varied with index visit location while injury-specific factors were largely comparable. Subsequent visits reflected high demand for follow-up treatment, increased concussive diagnoses, and sequelae-associated care. CONCLUSIONS: Adult outpatient presentations of head trauma remain poorly understood. The results of this study demonstrate the extensive magnitude of their occurrence and close association with need for follow-up care.

BACKGROUND: The Rothman Index is a comprehensive measure of overall patient status in the inpatient setting already in use at many medical centers. It ranges from 100 (best score) to -91 (worst score) and is calculated based on 26 variables encompassing vital signs, routine laboratory values, and organ system assessments from nursing rounds from the electronic medical record. Past research has shown an association of Rothman Index with complications, readmission, and death in certain populations, but it has not been evaluated in geriatric patients with hip fractures, a potentially vulnerable patient population. QUESTIONS/PURPOSES: (1) Is there an association between Rothman Index scores and postdischarge adverse events in a population aged 65 years and older with hip fractures? (2) What is the discriminative ability of Rothman Index scores in determining which patients will or will not experience these adverse events? (3) Are there Rothman Index thresholds associated with increased incidence of postdischarge adverse outcomes? METHODS: One thousand two hundred fourteen patients aged 65 years and older who underwent hip fracture surgery at an academic medical center between 2013 and 2016 were identified. Demographic and comorbidity characteristics were characterized, and 30-day postdischarge adverse events were calculated. The associations between a 10-unit change in Rothman Index scores and postdischarge adverse events, mortality, and readmission were determined. American Society of Anesthesiologists (ASA) class was used as a measure of comorbidity because prior research has shown its performance to be equivalent or superior to that of calculated comorbidity measures in this data set. We assessed the ability of Rothman Index scores to determine which patients experienced adverse events. Finally, Rothman Index thresholds were assessed for an association with increased incidence of postdischarge adverse outcomes. RESULTS: We found a strong association between Rothman Index scores and postdischarge adverse events (lowest score: odds ratio [OR] = 1.29 [1.18-1.41], p < 0.001; latest score: OR = 1.37 [1.24-1.52], p < 0.001) after controlling for age, sex, body mass index, ASA class, and surgical procedure performed. The discriminative ability of lowest and latest Rothman Index scores was better than those of age, sex, and ASA class for any adverse event (lowest value: area under the curve [AUC] = 0.641; 95% confidence interval [CI], 0.601-0.681; latest value: AUC = 0.640; 95% CI, 0.600-0.680); age (0.534; 95% CI, 0.493-0.575, p < 0.001 for both), male sex (0.552; 95% CI, 0.518-0.585, p = 0.001 for both), and ASA class (0.578; 95% CI, 0.542-0.614; p = 0.004 for lowest Rothman Index, p = 0.006 for latest Rothman Index). There was never a difference when comparing lowest Rothman Index value and latest Rothman Index value for any of the outcomes (Table 5). Patients experienced increased rates of postdischarge adverse events and mortality with a lowest Rothman Index of ≤ 35 (p < 0.05) or latest Rothman Index of ≤ 55 (p < 0.05). CONCLUSIONS: The Rothman Index provides an objective method of assessing perioperative risk in the setting of hip fracture surgery in patients older than age 65 years and is more accurate than demographic measures or ASA class. Furthermore, there are Rothman Index thresholds that can be used to identify patients at increased risk of complications. Physicians can use this tool to monitor the condition of patients with hip fracture, recognize patients at high risk of adverse events to consider changing their plan of care, and counsel patients and families. Further investigation is needed to determine whether interventions based on Rothman Index values contribute to improved outcomes or value of hip fracture care. LEVEL OF EVIDENCE: Level II, diagnostic study.

BACKGROUND: The prevalence of dialysis-dependent patients is growing, and an increasing number of these patients are being considered for total knee arthroplasty (TKA). Studies assessing the preoperative risk associated with TKA in this population are limited to institutional cohorts with small sample sizes or national inpatient databases that lack follow-up data. METHODS: The 2006-2015 National Surgical Quality Improvement Program databases were queried for adult patients undergoing elective TKA. Differences in 30-day any/severe/minor adverse event, need for reoperation, readmission, and mortality were compared for dialysis-dependent and nondialysis TKA patients using risk-adjusted logistic regression. To account for the smaller number of dialysis patients and variations in study populations, coarsened exact matching was used. The proportion of adverse events that occurred before vs after discharge was also assessed. RESULTS: In total, 250 dialysis-dependent patients and 163,560 nondialysis patients met inclusion criteria. After controlling for patient demographics (age, sex, body mass index, functional status) and overall health (American Society of Anesthesiologists class), matched analysis revealed dialysis-dependent patients to be significantly more likely to experience any adverse event (odds ratio = 2.01; 95% confidence interval [CI], 1.34-3.02; P = .001), severe adverse event (odds ratio = 2.49; 95% CI, 1.61-3.84; P < .001), reoperation (odds ratio = 2.38; 95% CI, 1.19-4.75; P = .014), readmission (odds ratio = 2.32; 95% CI, 1.47-3.66; P = .001), and mortality (odds ratio = 6.71; 95% CI, 2.99-22.50; P = .002). The majority of adverse outcomes occurred postdischarge. CONCLUSION: Independent of patient demographics and overall health (American Society of Anesthesiologists), patients undergoing dialysis before TKA are significantly more likely to experience 30-day adverse outcomes than matched nondialysis cohorts. Preoperative evaluation of bone health status and management of medical treatment are warranted in this fragile population. Cautious surgical planning, patient counseling, and heightened surveillance are necessitated throughout their perioperative period and postoperative recovery plans may need to be different from nondialysis counterparts. Furthermore, hospitals and physicians must take these increased risks into account when working on bundle payment reimbursement strategies and resource allocation. LEVEL OF EVIDENCE: 3.

BACKGROUND: The number of octogenarians undergoing revision total knee arthroplasty (TKA) is increasing. However, there has been a lack of studies investigating the perioperative course and safety of revision TKA performed in this potentially vulnerable population in a large patient population. The purpose of this study is to compare complications following revision TKA between octogenarians and 2 younger patient populations (<70 and 70-79 year olds). METHODS: Patients who underwent revision TKA were identified in the 2005-2015 National Surgical Quality Improvement Program database and stratified into 3 age groups: <70, 70-79, and ≥80 years. Baseline preoperative and intraoperative characteristics were compared between the 3 groups. Propensity score matched comparisons were then performed for 30-day perioperative complications, length of hospital stay, and readmissions. RESULTS: This study included 6523 (<70 years), 2509 (70-79 years), and 957 octogenarian patients who underwent revision TKA. After propensity matching, statistical analysis revealed only higher rates of blood transfusion and slightly longer length of stay in octogenarians compared to <70 year olds. Similarly, octogenarians had only higher rates of blood transfusion and slightly longer length of stay compared to 70-79 year olds. Notably, there were no differences in mortality or readmission between octogenarians compared to younger populations. CONCLUSION: These data suggest that revision TKA can safely be considered for octogenarians with the observation of higher rates of blood transfusion and slightly longer length of stay compared to younger populations. Octogenarian patients need not be discouraged from revision TKA solely based on their advanced age.

OBJECTIVES: To compare outcomes in patients on direct oral anticoagulants (DOACs) treated within 48 hours of last preoperative dose with those with surgical delays >48 hours. DESIGN: Retrospective cohort study. SETTING: Three academic Level 1 trauma centers. PATIENT SELECTION CRITERIA: Patients 65 years of age or older on DOACs before hip fracture treated between 2010 and 2018. Patients were excluded if last DOAC dose was >24 hours before admission, patient suffered from polytrauma, and/or delay to surgery was not attributed to DOAC. OUTCOME MEASURES AND COMPARISONS: Primary outcome measures were the postoperative complication rate as determined by diagnosis of deep venous thrombosis or pulmonary embolus, wound breakdown, drainage, or infection. Secondary outcomes included transfusion requirement, perioperative bleeding, length of stay, reoperation rates, readmission rates, and mortality. RESULTS: Two hundred five patients were included in this study, with a mean cohort age of 81.9 years (65-100 years), 64% were (132/205) female, and a mean Charlson Comorbidity Index of 6.4 (2-20). No significant difference was observed among age, sex, Charlson Comorbidity Index, or fracture pattern between cohorts (P > 0.05 for all comparisons). Seventy-one patients had surgery <48 hours after final preoperative DOAC dose; 134 patients had surgery >48 hours after. No significant difference in complication rate between the 2 cohorts was observed (P = 0.30). Patients with delayed surgical management were more likely to require transfusion (OR 2.39, 95% CI, 1.05-5.44; P = 0.04). Patients with early surgical management had significantly shorter lengths of stay (5.9 vs. 7.6 days, P < 0.005). There was no difference in estimated blood loss, anemia, reoperations, readmissions, 90-day mortality, or 1-year mortality (P > 0.05 for all comparisons). CONCLUSIONS: Geriatric patients with hip fracture who underwent surgical management within 48 hours of their last preoperative DOAC dose required less transfusions and had decreased length of stay, with comparable mortality and complication rates with patients with surgery delayed beyond 48 hours. Providers should consider early intervention in this population rather than adherence to elective procedure guidelines. LEVEL OF EVIDENCE: Prognostic Level III.

INTRODUCTION: The effect of orthopaedic fellowship subspecialization on surgical complications for patients with supracondylar fracture is unknown. This study seeks to compare the effect of subspecialty training on supracondylar fracture complications. METHODS: The American Board of Orthopaedic Surgery Part II Examination Case List database was reviewed for all supracondylar fractures from 1999 to 2016. Procedures were divided by fellowship subspecialty (trauma, pediatric, or other) and case volume and assessed by surgeon-reported surgical complications. Predictive factors of complications were analyzed using a binary multivariate logistic regression. RESULTS: Of 10,961 supracondylar fractures identified, 53.47% were done by pediatric fellowship-trained surgeons. Pediatric-trained surgeons had fewer surgical complications compared with their trauma or other trained peers (4.54%, 5.67%, and 6.24%; P = 0.001). Treatment by pediatric-trained surgeons reduced surgical complications (OR = 0.79, 95% CI: 0.66 to 0.94; P = 0.010), whereas increased case volume (31+ cases) showed no significant effect (OR = 0.79, 95% CI: 0.62 to 1.02; P = 0.068). Patient sex, age, and year of procedure did not affect complication rates, while those treated in the Southeast region of the United States and those with a complex fracture type were at increased odds. DISCUSSION: Treatment of supracondylar fractures by pediatric-trained surgeons demonstrates reduced surgeon-reported complications compared with their other fellowship-trained counterparts, whereas case volume does not. This suggests the value of fellowship training beyond pertinent surgical caseload among pediatric-trained surgeons and may lie in targeted education efforts.

BACKGROUND: HIV incidence and mortality are increasing in Ukraine despite their reductions globally, in part due to suboptimal antiretroviral therapy (ART) coverage in key populations of people with HIV (PWH) where the epidemic is concentrated. As physicians are gatekeepers to ART prescription, stigma and discrimination barriers are understudied as a key to meeting HIV treatment targets in key populations. METHODS: A national sample (N = 204) of ART-prescribing physicians in Ukraine were surveyed between August and November 2019. Participants underwent a series of randomized, hypothetical HIV clinical scenarios and decided whether to initiate or defer (or withhold) ART. Scenarios varied based on 5 distinct CD4 counts (CD4: 17, 176, 305, 470, or 520 cells/mL) and 10 different PWH key populations. Z scores and McNemar's test for paired samples were used to assess differences between key populations and CD4 count. Feeling thermometers were used to assess stigma-related measures toward key populations among physicians. RESULTS: Physicians were highly experienced (mean = 19 years) HIV treaters, female (80.4%), and trained in infectious diseases (76.5%). Patients who drink alcohol (range: 21.6%-23.5%) or use (PWUD range: 16.7%-20.1%) or inject (PWID range: 15.5%-20.1%) drugs were most likely to have ART deferred, even at AIDS-defining CD4 counts. PWID maintained on methadone, however, were significantly (p<0.001) less likely to have ART deferred compared with those who were not (range: 7.8%-12.7%) on methadone. Men who have sex with men (range: 5.4%-10.8%), transgender women (range: 4.9%-11.3%), sex workers (range: 3.9%-10.3%),and having an HIV-uninfected sex partner (range: 3.9%-9.3%) had the lowest likelihood of ART deferral. Increasing levels of stigma (i.e., feeling thermometers) towards a key population was correlated with ART deferral (i.e., discrimination). CONCLUSIONS: Despite international and Ukrainian guidelines recommending ART prescription for all PWH, irrespective of risk or CD4 count, ART deferral by experienced HIV experts remains high in certain key populations, especially in PWH and substance use disorders. Strategies that initiate ART immediately after diagnosis (i.e., rapid start antiretroviral therapy), independent of risk group, should be prioritized to truly mitigate the current epidemic.

During the past decade, US orthopedic residency graduates have become increasingly subspecialized presumably for decreased patient complications; however, no study has examined this clinical utility for foot and ankle (F&A) surgeries among different fellowship subspecialties. Data from American Board of Orthopaedic Surgery 1999 to 2016 Part II Board Certification Examinations were used to assess patients treated by F&A fellowship-trained, trauma fellowship-trained, and all other fellowship-trained orthopedic surgeons performing ankle fracture repair. Adverse events were compared by surgical complexity and fellowship status. Factors independently associated with surgical complications were identified using a binary multivariate logistic regression. A total of 45,031 F&A cases met inclusion criteria. From 1999 to 2016, the percentage of F&A procedures performed by F&A fellowship surgeons steadily increased. Surgical complications were significantly different between fellowship trainings (F&A, 7.23%; trauma, 6.65%; and other, 7.84%). This difference became more pronounced with more complicated fracture pattern. On multivariate regression, F&A fellowship training was associated with significantly decreased likelihood of surgeon-reported complications (odds ratio, 0.83; 95% CI, 0.76-0.92; P<.001), as was trauma fellowship training (odds ratio, 0.90; 95% CI, 0.81-0.99; P=.035). Despite presumed increased complexity of cases treated by F&A fellowship-trained surgeons, these patients had significantly decreased risk of surgeon-reported surgical complications, thus highlighting the value of F&A fellowship training. In the absence of vital patient comorbidity data in the American Board of Orthopaedic Surgery database, further research must examine specific patient comorbidities and case acuity and their influence on treatments and surgical complications between fellowship-trained and other orthopedic surgeons to further illuminate the value of subspecialty training.

Background: It remains unknown whether access to elite blind sports opportunities is globally balanced or matches the prevalence of blindness/visual impairment (VI). The primary objective of this study was to determine the rate of elite blind sports participation in each world region registered in the International Blind Sports Federation's (IBSA) and to assess its association with the global and regional prevalence of blindness/VI. The secondary objective was to determine the association between other covariates, such as age, vision class, and sex, with the number of IBSA-registered athletes from each region. Methods: A baseline estimate of blindness/VI data was established and used when comparing participation rates to blindness/VI rates. Descriptive statistics were used to describe sports participation and associated co-variates. Results: Among 123 member countries registered in IBSA, 31 did not have any completed registrations in blind sports, of which 22 had a prevalence of blindness/VI higher than the global average. During the summer season 2019, 738 (29.52%) IBSA athletes were female and 1762 (70.48%) were male. Conclusions: These results suggest elite blind/VI sport participation is limited independently from blindness/VI prevalence. Increasing blind-friendly sport resources, especially in low-and-middle-income countries (LMICs), would improve the rate of elite sport participation among athletes with blindness/VI.
RESUMO
OF BACKGROUND DATA: Pedicle screws are commonly placed with lumbar/lumbosacral fusions. Triggered electromyography (tEMG), which employs the application of electrical current between the screw and a complementary anode to determine thresholds of conduction, may be utilized to confirm the safe placement of such implants. While previous research has established clinical thresholds associated with safe screw placement, there is variability in clinical practice of anode placement which could lead to unreliable measurements. PURPOSE: To determine the variance in pedicle screw stimulation thresholds when using four unique anode locations (ipsilateral/contralateral and paraspinal/gluteal relative to tested pedicle screws). STUDY DESIGN: Prospective cohort study. Tertiary medical center. PATIENT SAMPLE: Twenty patients undergoing lumbar/lumbosacral fusion with pedicle screws using tEMG OUTCOME MEASURES: tEMG stimulation return values are used to assess varied anode locations and reproducibility based on anode placement. METHODS: Measurements were assessed across node placement in ipsilateral/contralateral and paraspinal/gluteal locations relative to the screw being assessed. R2 coefficients of correlation were determined, and variances were compared with F-tests. RESULTS: A total of 94 lumbosacral pedicle screws from 20 patients were assessed. Repeatability was verified using two stimulations at each location for a subset of the screws with an R2 of 0.96. Comparisons between the four anode locations demonstrated R2 values ranging from 0.76 to 0.87. F-tests comparing thresholds between each anode site demonstrated all groups not to be statistically different. CONCLUSION: The current study, a first-of-its-kind formal evaluation of anode location for pedicle screw tEMG testing, demonstrated very strong repeatability and strong correlation with different locations of anode placement. These results suggest that there is no need to change the side of the anode for testing of left versus right screws, further supporting that placing an anode electrode into gluteal muscle is sufficient and will avoid a sharp ground needle in the surgical field.

INTRODUCTION: American orthopaedists are increasingly seeking fellowship sub-specialization. One proposed benefit of fellowship training is decrease in complications, however, few studies have investigated the rates of medical and surgical complications for hip fracture patients between orthopedists from different fellowship backgrounds. This study aims to investigate the effect of fellowship training and case volume on medical and surgical outcomes of patient following hip fracture surgical intervention. METHODS: 1999-2016 American Board of Orthopedic Surgery (ABOS) Part II Examination Case List data were used to assess patients treated by trauma or adult reconstruction fellowship-trained orthopedists versus all-other orthopaedists. Rates of surgeon-reported medical and surgical adverse events were compared between the three surgeon cohorts. Using binary multivariate logistic regression to control of demographic factors, independent factors were evaluated for their effect on surgical complications. RESULTS: Data from 73,427 patients were assessed. An increasing number of hip fractures are being treated by trauma fellowship trained surgeons (9.43% in 1999-2004 to 60.92% in 2011-2016). In multivariate analysis, there was no significant difference in type of fellowship, however, surgeons with increased case volume saw significantly decreased odds of complications (16-30 cases: OR = 0.91; 95% CI: 0.85-0.97; p = 0.003; 31+ cases: OR = 0.68; 95% CI: 0.61-0.76; p<0.001). Femoral neck hip fractures were associated with increased odds of surgical complications. DISCUSSION: Despite minor differences in incidence of surgical complications between different fellowship trained orthopaedists, there is no major difference in overall risk of surgical complications for hip fracture patients based on fellowship status of early orthopaedic surgeons. However, case volume does significantly decrease the risk of surgical complications among these patients and may stand as a proxy for fellowship training. Fellows required to take hip fracture call as part of their training regardless of fellowship status exhibited decreased complication risk for hip fracture patients, thus highlighting the importance of additional training.

PURPOSE: Stationary training rollers enable wheelchair users to maintain physical health and train as athletes, which serves to treat and prevent immobility-associated chronic disease and improve cardiorespiratory fitness required for sports performance. However, conventional exercise equipment is largely inaccessible for persons with disabilities in low-resource areas, primarily due to cost. The aim of this study was to prototype, develop, and test a portable, cost-efficient stationary training device for wheelchair users in low-resource settings - The EasyRoller. MATERIALS AND METHODS: Stakeholder input from wheelchair athletes, trainers, and potential commercial manufacturers was solicited and utilized to conceptualize The EasyRoller design. The device was constructed from easily sourced, low cost components, following which it was user-tested with Para athletes. Feedback was analysed and incorporated into newer versions of the prototype.Results and conclusions: The EasyRoller creatively combines easily-sourced components to significantly cut down cost and ease both manufacture and repair for use in low-resource settings. The device is portable with a total weight of 34 pounds and total size of 42 linear inches while also affordable with a total cost of USD$199. Hereby, The EasyRoller has the potential to increase physical activity participation in populations with impairment who live in socioeconomically deprived world regions.Implications for rehabilitationExercise and physical activity are key aspects of health and quality of life for persons with disabilitiesStationary training rollers, devices that enable wheelchair users to train, are often bulky and expensive and therefore inaccessible for populations in socio-economically disadvantaged settingsThe EasyRoller is a portable and affordable training device that increases access to exercise and physical activity for these populations.

BACKGROUND CONTEXT: Prior studies investigating the association between Body Mass Index (BMI) and patient outcomes following spine surgery have had inconsistent conclusions, likely owing to insufficient power, confounding variables, and varying definitions and cutoffs for BMI categories (eg, underweight, overweight, obese, etc.). Further, few studies have considered outcomes among low BMI cohorts. PURPOSE: The current study analyzes how anterior lumbar interbody fusion (ALIF) perioperative outcomes vary along the BMI spectrum, using World Health Organization (WHO) categories of BMI. STUDY DESIGN/SETTING: A retrospective cohort study. PATIENT SAMPLE: Patients undergoing stand-alone one or two-level anterior lumbar interbody fusion (ALIF) found in the 2005-2018 American College of Surgeons National Surgical Quality Improvement Program (NSQIP) databases. OUTCOME MEASURES: Thirty-day adverse events, hospital readmissions, post-operative infections, and mortality. METHODS: Stand-alone one or two-level ALIF surgical cases were identified and extracted from the 2005-2018 National Surgical Quality Improvement Program (NSQIP) database. Posterior cases and those primary diagnoses of trauma, tumor, infection, or emergency presentation were excluded. Patients were then binned into WHO guidelines of BMI. The incidence of adverse outcomes within 30-day post-operation was defined. Odds ratios of adverse outcomes, normalized to the average risk of normal-weight subjects (BMI 18.5-24.9 kg/m3), were calculated. Multivariate analysis was then performed controlling for patient factors. RESULTS: In total, 13,710 ALIF patients were included in the study. Incidence of adverse events was elevated in both the underweight (BMI<18.5 kg/m3) and super morbidly obese (>50 kg/m3), however, multivariate risks for adverse events and postoperative infection were elevated for underweight patients beyond those found in any other BMI category. No effect was noted in these identical variables between normal, overweight, obese class 1, or even obese class 2 patients. Multivariate analysis also found overweight patients to show a slightly protective trend against mortality while the super morbidly obese had elevated odds. CONCLUSIONS: Underweight patients are at greater odds of experiencing postoperative adverse events than normal, overweight, obese class 1, or even obese class 2 patients. The present study identifies underweight patients as an at-risk population that should be given additional consideration by health systems and physicians, as is already done for those on the other side of the BMI spectrum.

ABSTRACT: Historic and present-day marginalization has resulted in a high burden of disease and worse health outcomes for American Indian and Alaska Native (AI/AN) communities in the United States. Musculoskeletal disease is the leading cause of disability for the general population in the U.S. today. However, few have examined musculoskeletal disease burden and access to orthopaedic surgical care in the AI/AN communities. A high prevalence of hip dysplasia, arthritis, back pain, and diabetes, and a high incidence of trauma and road traffic-related mortality, suggest a disproportionately high burden of musculoskeletal pathology among the AI/AN communities and a substantial need for orthopaedic surgical services. Unfortunately, AI/AN patients face many barriers to receiving specialty care, including long travel distances and limited transportation to health facilities, inadequate staff and resources at Indian Health Service (IHS)-funded facilities, insufficient funding for referral to specialists outside of the IHS network, and sociocultural barriers that complicate health-system navigation and erode trust between patients and providers. For those who manage to access orthopaedic surgery, AI/AN patients face worse outcomes and more complications than White patients. There is an urgent need for orthopaedic surgeons to participate in improving the availability of quality orthopaedic services for AI/AN patients through training and support of local providers, volunteerism, advocating for a greater investment in the IHS Purchased/Referred Care program, expanding telemedicine capabilities, and supporting community-based participatory research activities.

INTRODUCTION: Chondrosarcoma, although relatively uncommon, represents a significant percentage of primary osseous tumors. Nonetheless, there are few large-cohort, longitudinal studies of long-term survival and treatment outcomes of chondrosarcoma patients and none using the National Cancer Database (NCDB). METHODS: Chondrosarcoma patients were identified from the 2004-2015 NCDB datasets and divided on three primary tumor sites: appendicular, axial, and other. Demographic, treatment, and long-term survival data were determined for each group. Multivariate Cox analysis and Kaplan-Meier survival curves were generated to assess long-term survival over time for each. RESULTS: In total, 5,329 chondrosarcoma patients were identified, of which 2,686 were appendicular and 1,616 were axial. Survival was higher among the appendicular cohort than axial at 1-year, 5-year, and 10-year (89.52%, 75.76%, and 65.24%, respectively). Multivariate Cox analysis identified patients in the appendicular cohort to have significantly greater likelihood of death with increasing age category, distant metastases at presentation, and male sex (p<0.001 for each). Best outcomes for seen for those undergoing surgical treatment (p<0.001). Patients in the axial cohort were with increased likelihood of death with increasing age category and distant metastases (p<0.001), while surgical treatment with or without radiation were associated with a significant decrease (p<0.001). Kaplan-Meier survival analysis showed worst survival for the axial cohort (p<0.001) and patients with distant metastases at presentation (p<0.001). Survival was not significantly different between older (2004-2007) and more recent years (2012-2016) (p = 0.742). CONCLUSIONS: For both appendicular and axial chondrosarcomas, surgical treatment remains the mainstay of treatment due to its continued superiority for the long-term survival of patients, although advancements in survival over the last decade have been insignificant. Presence of distant metastases and axial involvement are significant, poor prognostic factors perhaps because of difficulty in surgical excision or extent of disease.

INTRODUCTION: Previous studies about osteosarcoma patient characteristics, management, and outcomes have limited patient numbers, combine varied tumor types, and/or are older studies. METHODS: Patients with osteosarcoma from the 2004 to 2015 National Cancer Database data sets were separated into axial, appendicular, and other. Demographic and treatment data as well as 1-, 5-, and 10-year survival were determined for each group. A multivariate Cox analysis of patient variables with the likelihood of death was performed, and the Kaplan Meier survival curves were generated. RESULTS: Four thousand four hundred thirty patients with osteosarcoma (3,435 appendicular, 810 axial, and 185 other) showed survival at 1-year, 5-year, and 10-year and was highest among the appendicular cohort (91.17%, 64.43%, and 58.58%, respectively). No change in survival was seen over the periods studied. The likelihood of death was greater with increasing age category, distant metastases, and treatment with radiation alone but less with appendicular primary site, treatment with surgery alone, or surgery plus chemotherapy. DISCUSSION: Despite advances in tumor management, surgical excision remains the best predictor of survival for osteosarcomas. No difference was observed in patient survival from 2004 to 2015 and, as would be expected, distant metastases were a poor prognostic sign, as was increasing age, male sex, and axial location.
