INTRODUCTION/BACKGROUND:To aid implementing an ethics curriculum in an orthopaedic residency program, the American Academy of Orthopaedic Surgeons (AAOS) created 14 ethics scenarios. Because delivery of this curriculum could be burdensome, an online module-based curriculum might be optimal. METHODS:Two cohorts of orthopaedic residents participated: cohort I completed 14 online ethics modules converted from the 14 AAOS ethics scenarios. For each module, we gave a multiple-choice assessment immediately before the module, immediately afterward, and 3 months afterward. Cohort II completed only the 14-module assessments at similar time intervals without any educational content. RESULTS:Cohort I demonstrated improvement in 3-month postmodule assessment scores in 11 of the 14 modules, 3 of which had statistical differences in baseline scores for cohort I and cohort II. We observed no statistical difference in scores within cohort II on repeat testing. DISCUSSION/CONCLUSIONS:This study demonstrates that 11 of the 14 AAOS ethics scenarios, converted to online modules, teach ethical concepts to orthopaedic residents. Orthopaedic residency programs may find it valuable to engage their residents in the ethics scenarios created by the AAOS to complement their ethics curriculum.

OBJECTIVES/OBJECTIVE:To assess the role self-reported treatment for a psychiatric diagnosis may play in long-term functional outcomes after operatively managed tibial plateau fractures. DESIGN/METHODS:Prospective cohort study. SETTING/METHODS:Academic medical center. PATIENTS/METHODS:Over an 11-year period, patients were screened and identified on presentation to the emergency department or in the clinical office for inclusion in an IRB-approved registry. A total of 245 patients were included in the study. Twenty-one patients reported treatment for a psychiatric diagnosis. INTERVENTION/METHODS:Surgical repair of tibial plateau fractures. MAIN OUTCOME MEASURE/METHODS:Patients were divided into 2 cohorts; 1 cohort being those who self-reported receiving treatment of a psychiatric diagnosis (PI); the other group being those who did not self-report receiving treatment of a psychiatric diagnosis (NPI). Three-month, 6-month, and long-term outcomes (mean = 18 months) were evaluated using the Short Musculoskeletal Function Assessment (SMFA), pain scores, and postoperative complications (infection, VTE, nonunion, and necessity for secondary operations). RESULTS:Pain scores were higher in patients who self-reported receiving treatment for a psychiatric diagnosis (P = 0.012). Long-term functional outcomes as measured by the SFMA were demonstrated to be worse in patients who self-reported treatment for a psychiatric diagnosis (P = 0.034). No differences existed between groups in regards to postoperative complications. Multiple linear regression analysis revealed that being treated for diagnosis of a mental health illness was an independent predictor of worse functional outcomes at long-term follow-up [B = 8.874, 95% confidence interval (CI) = 0.354-17.394, P = 0.041]. CONCLUSIONS:Mental health plays a crucial role in long-term outcomes after operative fixation of tibial plateau fractures. Patients who have been diagnosed with a mental health illness have significantly worse outcomes at long-term follow-up. LEVEL OF EVIDENCE/METHODS:Prognostic Level III.

OBJECTIVES/OBJECTIVE:1) Demonstrate that a validated trauma triage score for middle-aged and geriatric patients could identify those at high risk for mortality within the first two days of hospitalization and 2) determine the cost of care for this cohort of patients DESIGN:: Prospective cohort study SETTING:: Single Level 1 Trauma Center PATIENTS:: Patients 55 years and older who were evaluated in the emergency department setting by Orthopaedics or who met American College of Surgeons Tier 1-3 criteria INTERVENTION:: Calculation of validated trauma triage score, Score for Trauma Triage in Geriatric and Middle Aged (STTGMA), using patient's demographic, injury severity, and functional statusMain Outcome Measurements: length of stay, inpatient mortality, time between presentation and time of death, and direct variable costs of hospitalization RESULTS:: A total of 1470 consecutive patients (mean age of 72.2±11.9 years) were enrolled in this study, 17 of whom expired within 48 hours of presentation to the emergency department. These patients had a significantly higher trauma triage score than the rest of the cohort with a score of 50.9%±37.2% vs. 3.3%±9.5%, p<0.001 indicating that they had a mean risk of inpatient mortality of over 50%. Mean total cost/day was much higher in the cohort of patients who died within 48 hours of admission compared to all other trauma patients ($49,367±$79,057 vs. $3,966±$2,897 (p=0.031)). CONCLUSION/CONCLUSIONS:To achieve value-based care in this high-risk cohort, targeted cost-savings while improving patient outcomes and/or expediting goals-of-care and end-of-life goals is necessary and the STTGMA score allows for stratification of these patients in both mortality risk and cost profile. LEVEL OF EVIDENCE/METHODS:Prognostic, Level III.

Background /UNASSIGNED:Evaluation of resident physicians' communications skills is a challenging task and is increasingly accomplished with standardized examinations. There exists a need to identify the effective, efficient methods for assessment of communications skills. Objective /UNASSIGNED:We compared objective structured clinical examination (OSCE) and direct observation as approaches for assessing resident communications skills. Methods /UNASSIGNED:We conducted a retrospective cohort analysis of orthopaedic surgery resident physicians at a single tertiary care academic institution, using the Institute for Healthcare Communication "4 Es" model for effective communication. Data were collected between 2011 and 2015. A total of 28 residents, each with OSCE and complete direct observation assessment checklists, were included in the analysis. Residents were included if they had 1 OSCE assessment and 2 or more complete direct observation assessments. Results /UNASSIGNED: = .16), after adjusting for chance agreement. Conclusions /UNASSIGNED:Our results suggest that OSCE and direct observation tools provide different insights into resident communications skills (simulation of rare and challenging situations versus real-life daily encounters), and may provide useful perspectives on resident communications skills in different contexts.

BACKGROUND:Nondisplaced and minimally displaced fractures of the radial head and neck are common injuries, yet the role of physical therapy (PT) in their treatment is unclear. The aim of this trial was to assess the need for formal PT following a simple fracture of the radial head or neck. METHODS:Patients who had a nondisplaced or minimally displaced fracture of the radial head or neck and presented to 1 of 2 providers were enrolled prospectively between January 2014 and August 2016. Patients were randomized to receive outpatient PT or perform self-directed home exercise. The follow-up intervals were 6 weeks, 3 months, 6 months, and at least 1 year. The outcome measures were Disabilities of the Arm, Shoulder and Hand (DASH) scores; pain; time to clinical healing; and range of motion. Demographic data were analyzed using the Mann-Whitney U test and Fisher exact test. Independent-samples t tests were utilized to compare outcome measures. RESULTS:Fifty-one patients were enrolled in the study. The average follow-up was 16.6 months. Twenty-five patients were randomized to a home-exercise cohort, and 26 patients were randomized to a formal-outpatient-PT cohort. There were no significant differences in demographics between cohorts. At 6 weeks, the home-exercise cohort had better function as indicated by a significantly lower mean DASH score compared with the PT cohort (p = 0.021). At 3 months, 6 months, and final follow-up, there were no significant differences between cohorts for any outcome measure. CONCLUSIONS:Patients who performed home exercises after sustaining a nondisplaced or minimally displaced fracture of the radial head or neck demonstrated better early function at 6 weeks compared with patients who received formal PT. After 6 weeks, there were no significant differences in outcomes. These data suggest that prescribing PT for patients who have an isolated nondisplaced or minimally displaced fracture of the radial head or neck is not cost-effective and that instructing the patient to perform self-directed exercises will be followed by a similar outcome. LEVEL OF EVIDENCE/METHODS:Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

PURPOSE/OBJECTIVE:To describe one center's experience with nonunion of one or both bones of the forearm and report on the functional recovery of patients treated for a single- or 2-bone forearm nonunion. METHODS:We performed a retrospective analysis of 23 patients who presented to our institution over an 11-year period and underwent surgical repair of a forearm nonunion (radius, ulna, or both bones). The main outcome measurements included time to union, visual analog scale pain scores, range of motion, Short Musculoskeletal Function Assessment scores, and postoperative complications. RESULTS:Of the 23 patients, 21 (91.3%) healed their nonunion after a single surgical procedure. All patients ultimately healed their nonunion; 7 patients were healed at 3-month follow-up, 11 healed at 6-month follow-up, and 5 healed at 12-month follow-up. Mean visual analog scale pain scores improved considerably from presentation to latest follow-up. The mean range of motion at the latest follow-up was as follows: elbow 130.9° flexion-extension arc, forearm 78.5° pronation/77.8° supination, and wrist 76.1° palmar flexion/74.3° dorsiflexion. Mean Short Musculoskeletal Function Assessment arm and hand index scores improved significantly from baseline to the latest follow-up. Mean Short Musculoskeletal Function Assessment function, activity, and bothersome indices demonstrated improvement, though this was not statistically significant. Two patients required further surgery to achieve osseous union. One patient sustained an iatrogenic posterior interosseous nerve palsy, which resolved spontaneously. CONCLUSIONS:Repair of forearm nonunion with compression plating and bone grafting provides reliable clinical and functional outcomes. Patients treated surgically for nonunion of one or both of the forearm bones can expect to heal with the potential for considerable improvements in pain and function postoperatively. TYPE OF STUDY/LEVEL OF EVIDENCE/METHODS:Therapeutic IV.

Purpose/UNASSIGNED:To identify patient characteristics associated with adverse events in Achilles tendon rupture (ATR) surgical repair cases. Methods/UNASSIGNED:A high risk (HR) cohort group of ATR patients were compared to healthy controls in the ACSNSQIP database with multivariate regression analysis. Results/UNASSIGNED:Overall, 2% (n = 23) of the group sustained an AE postoperatively, most commonly superficial SSI (0.9%, n = 10). Multivariate analysis did not reveal any patient characteristics to be significantly associated with the occurrence of an AE or superficial SSI. Conclusions/UNASSIGNED:Obesity, diabetes and a history of smoking did not predispose patients to significantly more AEs in the 30 day postoperative period following ATR repair in this study.

BACKGROUND:The number of periprosthetic proximal femoral fractures is expected to increase with the increasing prevalence of hip arthroplasties. While native hip fractures have a well-known association with mortality, there are currently limited data on this outcome among the subset of patients with periprosthetic proximal femoral fractures. METHODS:Using the New York Statewide Planning and Research Cooperative System, we identified patients from 60 to 99 years old who were admitted to a hospital in the state with a periprosthetic proximal femoral fracture (n = 1,655) or a native hip (femoral neck or intertrochanteric) fracture (n = 97,231) between 2006 and 2014. Within the periprosthetic fracture cohort, the indication for the existing implant was not available in the data set. We used mixed-effects regression models to compare mortality at 1 and 6 months and 1 year for periprosthetic compared with native hip fractures. RESULTS:The risk of mortality for patients who sustained a periprosthetic proximal femoral fracture was no different from that for patients who sustained a native hip fracture at 1 month after injury (3.2% versus 4.6%; odds ratio [OR], 0.90; 95% confidence interval [CI], 0.68 to 1.19; p = 0.446), but was lower at 6 months (3.8% versus 6.5%; OR, 0.74; 95% CI, 0.57 to 0.95; p = 0.020) and 1 year (9.7% versus 15.9%; OR, 0.71; 95% CI, 0.60 to 0.85; p < 0.001). Among periprosthetic proximal femoral fractures, factors associated with a significantly increased risk of mortality at 1 year included advanced age, male sex, and higher Deyo comorbidity scores. CONCLUSIONS:In the acute phase, any type of hip fracture appears to confer a similar risk of death. Over the long term, however, periprosthetic proximal femoral fractures are associated with lower mortality rates than native hip fractures, even after accounting for age and comorbidities. LEVEL OF EVIDENCE/METHODS:Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Purpose/UNASSIGNED:The purpose of this study was to compare hospital quality outcomes in patients over the age of 60 undergoing fixation of hip fracture based on their anticoagulation status. Materials and Methods/UNASSIGNED:Patients aged 60 and older with isolated hip fracture injuries treated operatively at 1 academic medical center between October 2014 and September 2016 were analyzed. Patients on the following medications were included in the anticoagulation cohort: warfarin, clopidogrel, aspirin 325 mg, rivaroxaban, apixaban, dabigatran, and dipyridamole/aspirin. We compared outcome measures including time to surgery, length of stay (LOS), transfusion rate, blood loss, procedure time, complication rate, need for intensive care unit (ICU)/step-down unit (SDU) care, discharge disposition, and cost of admission. Outcomes were controlled for age, Charlson comorbidity index (CCI), and anesthesia type. Results/UNASSIGNED:= .026). Lastly, there was no difference in cost of care. Conclusion/UNASSIGNED:This study highlights that anticoagulation status alone does not independently put patients at increased risk with respect to LOS, surgical outcomes, and cost of hospitalization.

Treatment of traumatic bone defects is dictated by a multitude of clinical factors including the defect size, patient comorbidities, soft tissue condition, and the possibility of infection present in the defect. With a variety of treatment strategies described, it is critical to choose the approach that will maximize outcomes in addressing this difficult problem. When addressing small-scale defects, bone grafting is the primary treatment. For large-scale defects, there are two major options to consider: induced membrane technique and distraction osteogenesis. Choosing between these two techniques should be based on the associated soft tissue injury, the local vascularity, and the possibility of residual infection. This review will focus on the current management principles and strategies in the treatment of bone defects after orthopedic trauma and the existing literature to support each of these treatment options.
