OBJECTIVE: We developed a series of orthopedic unannounced standardized patient (USP) encounters for the purpose of objective assessment of residents during clinic encounters. DESIGN: Consecutive case-series. SETTING: NYU-Langone Multi-center Academic University Hospital System. PARTICIPANTS: NYU-Langone/Hospital for Joint Diseases Orthopedic Surgery residents; 48 consecutive residents assessed. METHODS: Four orthopedic cases were developed. USPs presented themselves as patients in outpatient clinics. Residents were evaluated on communication skills (information gathering, relationship development, and education and counseling). USPs globally rated whether they would recommend the resident. RESULTS: Forty-eight USP encounters were completed over a 2-year period. Communication skills items were rated at 51% (+/-30) "well done." Education and counseling skills were rated as the lowest communication domain at 33% (+/-33). Residents were globally recommended based on communication skills in 63% of the encounters recommended in 70% of encounters based on both professionalism and medical competence. CONCLUSIONS: The USP program has been useful in assessing residents' clinical skills, interpersonal and communications skills, and professionalism. Use of USP in orthopedic surgery training programs can be an objective means for trainee assessment.

The purpose is to identify risk factors of functional outcome following proximal humerus open reduction and internal fixation. Patients treated for proximal humerus fractures with open reduction and internal fixation were enrolled in a prospective data registry. Patients were evaluated for function using the Disability of the Arm, Shoulder and Hand score for 12 months and as available beyond 12 months. Univariate analyses were conducted to identify variables associated with functional outcome. Significant variables were included in a multivariate regression predicting functional outcome. Demographics and minimum of 12 month follow-up were available for 129 patients (75%). Multiple regression demonstrated postoperative complication (B=8.515 p=0.045), education level (B=-6.269p<0.0005), age (B=0.241p=0.049) and Charlson Comorbidity Index (B=6.578, p=0.001) were all significant predictors of functional outcome. Orthopaedic surgeons can use education level, comorbidities, age, and postoperative complication information to screen patients for worse outcomes, establish expectations, and guide care.

This study was conducted to determine whether proximal humerus fracture patterns as defined by the Orthopaedic Trauma Association (AO/OTA) classification and the Neer 4-part system predicted functional outcomes for patients treated with open reduction and internal fixation with locked plates and, if so, which system correlated better with outcomes. During a 12-year period, 213 patients with a displaced proximal humerus fracture who underwent surgical treatment with a locking plate at 1 academic institution were prospectively followed. All patients were treated in a similar way and were followed by the operating surgeon at routine intervals. Functional outcomes were measured with the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Of these patients, 164 were available for analysis. Functional outcomes based on DASH scores did not differ significantly by Neer system, AO/OTA classification, or varus/valgus humeral head alignment at more than 12 months postoperatively. However, patients with Neer 4-part fracture and AO/OTA type 11-C fracture had worse shoulder range of motion in terms of forward elevation and external rotation. Time to healing and complication rates also were not significantly different based on either classification system. Fracture classification can predict shoulder range of motion 12 months after surgical fixation, but its use is limited in predicting functional outcome scores, time to healing, and complication rates. Patients who undergo surgical repair of a proximal humerus fracture can expect good functional results independent of the initial injury pattern, but more severe fracture patterns may lead to decreased shoulder range of motion.

Introduction/UNASSIGNED:Frailty in elderly trauma populations has been correlated with an increased risk of morbidity and mortality. The Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA) is a validated mortality risk score that evaluates 4 major physiologic criteria: age, comorbidities, vital signs, and anatomic injuries. The aim of this study was to investigate whether the addition of additional frailty variables to the STTGMA tool would improve risk stratification of a middle-aged and elderly trauma population. Methods/UNASSIGNED:A total of 1486 patients aged 55 years and older who met the American College of Surgeons Tier 1 to 3 criteria and/or who had orthopedic or neurosurgical traumatic consultations in the emergency department between September 2014 and September 2016 were included. The STTGMAORIGINAL and STTGMAFRAILTY scores were calculated. Additional "frailty variables" included preinjury assistive device use (disability), independent ambulatory status (functional independence), and albumin level (nutrition). The ability of the STTGMAORIGINAL and the STTGMAFRAILTY models to predict inpatient mortality was compared using area under the receiver operating characteristic curves (AUROCs). Results/UNASSIGNED:There were 23 high-energy inpatient mortalities (4.7%) and 20 low-energy inpatient mortalities (2.0%). When the STTGMAORIGINAL model was used, the AUROC in the high-energy and low-energy cohorts was 0.926 and 0.896, respectively. The AUROC for STTGMAFRAILTY for the high-energy and low-energy cohorts was 0.905 and 0.937, respectively. There was no significant difference in predictive capacity for inpatient mortality between STTGMAORIGINAL and STTGMAFRAILTY for both the high-energy and low-energy cohorts. Conclusion/UNASSIGNED:The original STTGMA tool accounts for important frailty factors including cognition and general health status. These variables combined with other major physiologic variables such as age and anatomic injuries appear to be sufficient to adequately and accurately quantify inpatient mortality risk. The addition of other common frailty factors that account for does not enhance the STTGMA tool's predictive capabilities.

Background/UNASSIGNED:Tibial plateau fractures can be devastating traumatic injuries to the knee, particularly in active athletes. Purpose/Hypothesis/UNASSIGNED:The purpose of this study was to report on the return to participation in recreational athletics after operatively managed tibial plateau fractures. In addition, this study assessed factors associated with the ability to return to participation in recreational athletics after tibial plateau fractures treated with open reduction internal fixation and compared final outcomes between patients who were able to return to recreational athletics and those who could not. The hypothesis was that returning to participation in recreational athletics would be dependent on the time from surgery after operative fixation of tibial plateau fractures. Less severe injuries would be associated with a quicker return to athletics. Study Design/UNASSIGNED:Case-control study; Level of evidence, 3. Methods/UNASSIGNED:All tibial plateau fractures treated by 1 of 3 surgeons at a single academic institution over an 11-year period were prospectively followed. Final outcomes were evaluated using the Short Musculoskeletal Function Assessment at latest follow-up. All complications were recorded at each follow-up. Differences between the groups were compared using Student t tests for continuous variables. Chi-square analysis was used to determine whether differences between categorical variables existed. Logistic regression was performed to assess independent variables associated with returning to participation in recreational athletics. Results/UNASSIGNED:A total of 169 patients who underwent operative management of their tibial plateau fracture reported participation in recreational athletics before their injury. By the 6-month time point, 48 patients (31.6%) had returned to participation in recreational athletics, and at final follow-up (mean, 15 months), 89 patients (52.4%) had returned to participation in recreational athletics. Predictors of returning to recreational athletics included white race, female sex, social alcohol consumption, younger age, increased range of motion (ROM), low-energy Schatzker patterns (I-III), injuries not inclusive of orthopaedic polytrauma or open fractures, and no postoperative complications. White race, social alcohol consumption, and increased ROM were associated with returning to athletics at both 6-month and final follow-up. Lack of a venous thromboembolism was associated with returning to athletics at final follow-up. Patients who returned to recreational athletics had associations with better functional outcomes and emotional status than those who did not. Conclusion/UNASSIGNED:The number of patients who returned to participation in recreational athletics gradually increased over time after operative fixation of tibial plateau fractures. Less severe injuries and a lack of postoperative complications were associated with a quicker return to athletics. Predictors of returning to participation in recreational athletics after operatively managed tibial plateau fractures can be used to target patients at risk of not returning to play to provide interventions aimed at improving their recovery, such as early knee range of motion, muscle strengthening, and participation in low-impact activities.

OBJECTIVES: To assess the presence of fracture site gross motion on physical examination to predict humeral shaft fracture progression to nonunion in patients managed nonoperatively. DESIGN: Retrospective cohort study. SETTING: Single trauma level 1 institutional center. PATIENTS: Eighty-four consecutive patients undergoing nonoperative treatment of a diaphyseal humeral shaft fracture were identified. The average age of the population was 48.3 years, and 50% of the cohort was men. INTERVENTION: Clinical examination for fracture stability was routinely performed on patients by the treating physicians and documented it in the medical record. Patients were followed until union or surgery for persistent fracture mobility. MAIN OUTCOME MEASUREMENTS: Stability was graded if there was motion at the site (1: motion of any kind and 0: moved as a unit). RESULTS: Seventy-three patients (87%) healed their fracture within our study cohort by 6 months postfracture. Of the remaining 11 patients, after discussion with their treating physicians about the option of surgical intervention, 8 chose to undergo open reduction internal fixation at an average of 8 months, 1 proceeded nonsurgical interventions, and 2 were lost of follow-up. If the humeral shaft fracture site was mobile at 6 weeks follow-up visit, it identified future fracture nonunion with 82% sensitivity and 99% specificity (only 1 patient with motion at 6 weeks proceeded to fracture union). CONCLUSION: With a high negative predictive value, clinical examination of fracture motion at 6 weeks should be assessed in every patient to determine which patients should obtain closer follow-up for the risk of nonunion progression. Knowledge of gross fracture motion can be used in the shared decision-making model in counseling about early surgical options. LEVEL OF EVIDENCE: Diagnostic Level III.

The internet is a popular resource for orthopedic fellowship applicants. We conducted a study to assess the accessibility of orthopedic trauma fellowship (OTF) program websites and to evaluate the content on the sites. We queried the online database of the Orthopaedic Trauma Association (OTA) and the online Fellowship and Residency Electronic Interactive Database (FREIDA) to assess available OTF program links. We used Google to assess how accessible the sites are from outside the databases. We then analyzed accessible sites for content pertinent to OTF applicants. Of the 49 OTF programs identified, 42 (86%) had their websites accessible from Google and FREIDA links. The OTA database had no OTF website links. Analysis of the 42 accessible OTF sites revealed they had an average of 40% (range, 0%-75%) of assessed content, with operative experience on 88% of sites and a program description on 93% of sites. OTF programs with >1 fellow had significantly more education content (48% vs 33%; P = .043) and total content (46% vs 37%; P = .01) on their sites than OTF programs with 1 fellow. Accessibility and content of OTF websites are highly variable and largely deficient. OTF programs should focus on improving their website accessibility and content.

OBJECTIVE: To compare the cost and outcomes of patients treated at orthopaedic teaching hospitals (OTHs) with those treated at nonteaching hospitals (NTHs). DESIGN: Retrospective study. SETTING: The Statewide Planning and Research Cooperative Systems (SPARCS) database, which includes all admissions to New York State hospitals from 2000-2011. PATIENTS/PARTICIPANTS: A total of 165,679 patients with isolated closed hip fracture 65 years of age and older met inclusion criteria. Of them, 57,279 were treated at OTH and 108,400 were treated at NTH. INTERVENTION: Admission for the management of a hip fracture. MAIN OUTCOME MEASURE: Cost, length of stay (LOS), and inpatient mortality. RESULTS: Univariate analysis shows that mean total hospital costs were higher at OTH ($16,576 +/- $17,514) versus NTH ($13,358 +/- $11,366) (P < 0.001); LOS was equivalent at OTH (8.0 +/- 9.0 days) versus NTH (8.0 +/- 7.6 days) (P = 0.904); and mortality was lower in OTH (3.4%) versus NTH (4.0%) (P < 0.001). In the multivariate total cost analysis, in addition to demographic differences, we identified total hospital beds and total ICU beds as significant confounding variables. Interestingly, when controlling for these patient and hospital factors, OTH designation was not a significant predictor of cost. In addition, multivariate analysis found that OTH status decreased LOS by 0.743 days (95% confidence interval: 0.632-0.854, P < 0.001) and mortality by 21% (odds ratio 0.794, 95% confidence interval: 0.733-0.859, P < 0.001), confirming the univariate trends. CONCLUSIONS: While OTH may seem to have higher hospital costs for operative hip fractures on cursory analysis, controlling for patient and hospital factors including hospital bed number negates this effect such that OTH has no additional cost compared with NTH. In addition, OTH status is associated with shorter LOS and lower in-hospital mortality. With the results of this study, health care systems and patients should feel confident that the quality of care at teaching hospitals is no less and potentially better than that at NTH with no added cost.
