HYPOTHESIS Surgical stabilization of displaced clavicle fractures was once considered to have rare indications. Our purpose was to present the clinical and economic effects of surgical management using data collected from operative and nonoperative patients. METHODS Our fracture database was queried from January 1, 2005, to January 1, 2010, identifying(More)
Historically, surgical treatment of acute mid-shaft clavicle fractures has excellent outcomes with low rates of nonunion. More complex fracture patterns with significant comminution may limit the fixation that can be obtained with a single plate. The authors describe the surgical technique and case series of patients treated with extraperiosteal dual(More)
OBJECTIVES To compare the results of surgical stabilization with locked plating to nonoperative care of flail chest injuries. DESIGN Retrospective case-control study. SETTING Level II trauma center. PATIENTS/PARTICIPANTS From January 2005 to January 2010, 22 patients with flail chest treated with locked plate fixation were compared with a matched(More)
Our purpose was to perform a clinical and financial analysis of a pricing matrix system on operative hip fracture care concerning hemiarthroplasty for displaced femoral neck fractures in elderly low demand patients. Data analysis on 81 pre-matrix and 88 post-matrix patients demonstrated no significant differences in age, sex, ASA or fracture pattern between(More)
Small studies have shown that patients who undergo TKA following a distal femur and/or tibial plateau fracture have inferior results. The purpose of this study was to evaluate the mid-term outcomes of a large group of patients undergoing TKA following periarticular knee fractures. We identified 531 patients who underwent a TKA following a periarticular(More)
BACKGROUND Surgical treatment of proximal humeral fractures in the elderly pose challenges in decision making. Reverse total shoulder arthroplasty (RTSA) has been established as a reliable option for salvage of failed hemiarthroplasty, although few studies have analyzed RTSA after failed open reduction with internal fixation (ORIF). This study evaluated the(More)
OBJECTIVES Fellowship-trained orthopaedic traumatologists are presumably taught skill sets leading to "best practice" outcomes and more efficient use of hospital resources. This should result in more favorable economic opportunities when compared with general orthopaedic surgeons (GOSs) providing similar clinical services. The purpose of our study was to(More)
Unloaded shortening speeds, V, of muscle are thought to be limited by actin-bound myosin heads that resist shortening, or V = a·d·τon(-1) where τon(-1) is the rate at which myosin detaches from actin and d is myosin's step size. The a-term describes the efficiency of force transmission between myosin heads, and has been shown to become less than one at low(More)
OBJECTIVE The purpose of this study was to evaluate which primary wound closure technique for ankle fractures affords the most robust perfusion as measured by laser-assisted indocyanine green angiography (LA-ICGA): Allgöwer-Donati or vertical mattress. DESIGN Prospective, randomized. SETTING Level 1 Academic Trauma Center. PATIENTS/PARTICIPANTS Thirty(More)
OBJECTIVES The purpose of this study was to evaluate pediatric scapula fractures occurring in high-energy motorized vehicle accidents and their associated injury patterns in a pediatric patient population. METHODS One thousand nine hundred sixty-eight pediatric patients who presented after either on-road or off-road motorized vehicle accidents between(More)
