Abstract
PURPOSE OF REVIEW Many aspects of developmental hip dysplasia (DDH) care and evaluation are still active areas of debate. Recent studies have provided more insight into these topics such as strategies for reducing osteonecrosis, assessing hip reduction after closed and open reduction, and the management of residual acetabular dysplasia. RECENT FINDINGS The presence of the ossific nucleus at the time of reduction does not alter the risk of osteonecrosis. The risk of osteonecrosis may be higher when hips are immobilized in excessive abduction. Limited sequence MRI may be the best choice for assessing hip reduction after closed and open reduction; however, new technologies are emerging such as 3D fluoroscopy and perfusion MRI. The treatment of residual acetabular dysplasia with bracing has been shown to be effective and the decision to perform a pelvic osteotomy is based on patient-specific factors. The spectrum of DDH treatment has evolved over the past several decades. Recent studies have provided insights into strategies for osteonecrosis prevention, hip evaluation during after reduction, and the management of residual acetabular dysplasia. However, there is ample room for additional and more rigorous studies guiding advanced imaging for assessing hip reduction such as 3D fluoroscopy and perfusion MRI, as well as the management of residual acetabular dysplasia.

Abstract
OBJECTIVE The impact of new pedagogical methods such as case-based learning (CBL) rather than traditional lectures in graduate medical education is poorly defined. We hypothesized that using CBL in lieu of lectures in an orthopedic surgery residency anatomy course would lead to increased resident engagement, improved resident satisfaction, and similar knowledge acquisition. DESIGN A prospective, observational study design was used. CBL sessions were developed for an orthopedic surgery residency anatomy course. Content was delivered in 6 sessions (3 traditional lecture-based and 3 CBL) taught by the same attending surgeon. Engagement was measured every 10 minutes by 2 trained observers using a standardized protocol. Resident satisfaction was surveyed and knowledge acquisition tested. Data from the course were scored separately for CBL verses lectures and compared statistically. SETTING Orthopedic surgery residency program at the University of California, San Francisco. PARTICIPANTS Orthopedic surgery interns and residents (n = 35). RESULTS No significant differences were measured in resident engagement (83% vs 85%, p = 0.664) or in knowledge acquisition (84% vs 78%, p = 0.056) in CBL verses lecture sessions, respectively. CBL sessions were judged equally valuable compared to lectures with high satisfaction rates across all survey measures. CONCLUSIONS Residents demonstrated similar engagement and satisfaction with CBL compared to lectures with equivalent knowledge acquisition, suggesting both pedagogical methods are effective for a highly motivated group of learners.

Abstract
Background: This study aims to describe the long-term patient-reported outcomes after surgery for hypothenar hammer syndrome (HTHS) and to identify factors associated with inferior outcomes. Methods: We retrospectively identified 27 patients who underwent surgical intervention for HTHS from 2002 to 2016. Fifteen patients (56%) completed outcome questionnaires: Quick Disabilities of the Arm, Shoulder, and Hand, Cold Intolerance Symptom Severity (CISS) survey, Patient-Reported Outcomes Measurement Information System Upper Extremity Computer Adaptive Test, and Patient-Reported Outcomes Measurement Information System Pain Interference Computer Adaptive Test. The median questionnaire follow-up was 7.2 years (interquartile range, 3.1-9.9). Outcomes were compared across different surgical techniques, and the influence of patient-related factors on outcomes was also evaluated. Results: Six (40%) patients experienced complete symptom resolution, 6 (40%) had improvement without complete resolution, 1 (7%) had resolution followed by recurrence, and 2 (13%) reported no improvement. The most common symptom after surgical intervention was cold intolerance. Questionnaire scores were similar across ligation, direct repair, and vein graft vascular reconstruction. Patients had better CISS scores if they had surgery on their nondominant hand (13.2 vs 38.6) and did not have a manual labor job (18.1 vs 40.5). Conclusions: Surgery for HTHS leads to moderate long-term improvement in patient-reported outcomes. Different surgical techniques yield similar symptomatic relief. Manual labor and surgery of the dominant hand are associated with worse CISS scores.

Abstract
OBJECTIVE Resuscitative Thoracotomy or Emergency Department Thoracotomy (EDT) is a time-sensitive and potentially life-saving procedure. Yet, trainee experience with this procedure is often limited in both clinical and simulation settings. We sought to develop a high-fidelity EDT simulation module and assessment tool to facilitate trainee education. DESIGN Using the Kern model for curricular development, a group of expert trauma surgeons identified EDT as a high-stakes, low-frequency procedure. Task analysis identified 5 key steps of EDT: (1) opening chest/rib spreader utilization; (2) pericardiotomy/cardiac repair; (3) open cardiac massage; (4) clamping aorta; and (5) control of pulmonary hilum. A high-fidelity simulator with beating-heart technology was built. The previously validated Objective Structured Assessment of Technical Skills (OSATS) was adapted to create the "EDT-OSATS" which assessed performance along several domains: (1) Surgical technique (key steps); (2) general skills; and (3) global rating. A pilot test was performed to compare board-certified trauma surgeons (i.e., Experts) with categorical general surgery interns (i.e., Novices). Each subject received preparatory materials, completed a presimulation quiz, performed a videotaped procedure on the EDT simulator, and completed a postmodule survey. Two independent raters scored performances using the EDT-OSATS. Groups were compared in descriptive and unadjusted analyses. We hypothesized that our EDT simulation module would distinguish between expert vs novice performance and improve trainee confidence. SETTING Simulation laboratory at Massachusetts General Hospital in Boston, MA. PARTICIPANTS Trauma surgeons (Experts, n = 6) and categorical general surgery interns (Novices, n = 8). RESULTS Experts scored significantly higher than Novices on nearly all components of the EDT-OSATS, including: (1) surgical technique: pericardiotomy (4.2 vs 3.4, p = 0.040), cardiac massage (3.6 vs 2.4, p = 0.028), clamping aorta (4.1 vs 3.3, p = 0.035), control of pulmonary hilum (4.8 vs 3.4, p < 0.001); (2) general skills: time/motion (4.1 vs 2.9, p = 0.011), knowledge and handling of instruments (4.3 vs 3.1, p = 0.004), and (3) global rating (3.9 vs 2.9, p = 0.026). There was no statistical difference between groups on opening chest/rib spreader utilization (3.8 vs 3.3, p = 0.352) or procedure time (204sec vs 227sec, p = 0.401), though Experts scored numerically higher than Novices on every measure. Novices reported significantly increased confidence after the simulation (3.1 vs 1.4, p = 0.001). Ninety-three percent (13/14) of participants found the simulator realistic. CONCLUSIONS Our novel high-fidelity beating-heart EDT simulator is realistic and improves trainee confidence in this low-frequency, high-stakes emergency procedure. The EDT-OSATS tool differentiates between performances of experienced surgeons vs novice trainees on the beating-heart simulator. This training module and accompanying assessment instrument hold promise as a learning tool for clinicians who may perform emergency department thoracotomy.

Abstract
BACKGROUND Dermatopathologists assess wounds secondary to trauma, infection, or oncologic resection that can be challenging to reconstruct. OASIS Ultra, an extracellular matrix, has been described for use in chronic and burn wounds. The aim of this pilot study is to assess wound healing in post-traumatic and infective wounds treated with OASIS using histological markers of repair. MATERIALS AND METHODS Adults with traumatic, infective or iatrogenic wound defects with size precluding primary closure were eligible. Half the wound was randomly assigned to receive OASIS plus standard therapy; the other half received standard of care (SOC) therapy. During dressing changes, standardized-scale photographs were taken and biopsies obtained. Histologic sections were reviewed for degree of acute inflammation and extent of tissue repair. Neutrophils, edema, hemorrhage, necrosis, fibroblasts, collagen density and neovascularization were semi-quantitatively assessed. RESULTS Forty-four skin biopsies from 7 patients with 10 acute wounds met eligibility criteria. Histologically, OASIS samples demonstrated improved acute inflammation scores compared to SOC. No patients experienced OASIS-related complications. OASIS-treated wound halves trended toward more wound contraction and improved tissue repair. CONCLUSION Our scoring system aids histopathological wound assessment. Treatment of critical-sized, post-traumatic, acute wounds with OASIS resulted in decreased inflammation, and potentially more advanced wound healing, compared to SOC.
