BACKGROUND Magnetic resonance imaging (MRI) is widely used as a preoperative tool to estimate the size of articular cartilage defects to optimize treatment selection. However, the reliability of MRI sizing of cartilage defects is not well understood. Hypothesis/ PURPOSE The purpose of this investigation was to compare the size of knee articular cartilage(More)
Soft tissue sarcomas have a mortality rate of 40% to 60%, with local recurrence being a poor prognostic factor for overall survival. Three-percent nondiluted hydrogen peroxide is hypothesized to be an effective local adjuvant. The purpose of this study was to identify risk factors for local recurrence in high-grade soft tissue sarcomas and to determine(More)
The most effective way to teach and assess a resident's knowledge of musculoskeletal medicine, including orthopedic-specific surgical skills, remains unclear. We designed a surgical skills training session to educate junior-level orthopedic residents in 4 core areas: comfort with basic power equipment, casting/splinting, suturing, and surgical instrument(More)
INTRODUCTION Humeral shaft nonunions can lead to morbidity from subsequent operations, complications and impaired function. Currently there is no evidenced-based consensus for treatment of humeral shaft nonunions. AIM We aimed to summarize and analyze union rates and complications after operative treatment for humeral shaft nonunion. METHODS Studies(More)
Background: This study addresses the prevalence of discrete pathophysiology accounting for patients' symptoms during diagnostic wrist arthroscopy in individuals with wrist pain without a specific preoperative diagnosis. Secondarily, we determined the number and type of surgeries subsequent to diagnostic wrist arthroscopy. Methods: Between January 2000 and(More)
Accurate assessment of partial-thickness flexor tendon lacerations in the hand is difficult owing to the subjectivity of evaluation. In this study, we created 12 partial-thickness flexor tendon lacerations in a cadaveric hand, evaluated the accuracy of 6 orthopedic residents and 4 fellowship-trained hand surgeons in estimating the percentage thickness of(More)
PURPOSE This study was conducted to evaluate reports of clinical outcomes of isolated capitellar fractures. MATERIALS AND METHODS We conducted a systematic review of medical databases reporting clinical outcomes of patients undergoing nonoperative and operative management of isolated capitellar fractures. RESULTS We identified 28 studies for inclusion(More)
BACKGROUND Radial head compression against the capitellum may cause concomitant fracture of the capitellum. The purpose of this study was to investigate if radial head fracture type is associated with a concomitant fracture of the capitellum. PATIENTS AND METHODS Data were identified from five area hospitals. We retrieved records of patients older than 18(More)
PURPOSE To identify factors associated with reoperation for early loosening or breakage of implants or nonunion after operative treatment of AO type C distal humerus fractures. METHODS We retrospectively analyzed 129 adult patients who had operative treatment of an isolated AO type C distal humerus fracture at 1 of 5 hospitals to determine factors(More)
