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)
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)
The use of multichannel array head coils in functional and structural magnetic resonance imaging (MRI) provides increased signal-to-noise ratio (SNR), higher sensitivity, and parallel imaging capabilities. However, their benefits remain to be systematically explored in the context of resting-state functional connectivity MRI (fcMRI). In this study, we(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)
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)
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)
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)
OBJECTIVES The American Academy of Orthopedic Surgeons and the Orthopedic Trauma Association have released guidelines for the provision of orthopedic trauma services such as adequate stipends, designated operating rooms, ancillary staff, and guaranteed reimbursement for indigent care. One recommendation included a provision for hospital-based physician(More)
Traumatic injuries to peripheral nerves pose complex challenges to both military and civilian physicians. Treatment of nerve injuries must consider all aspects of the inherent disability. Pain control is of paramount importance. Little will be accomplished until pain is brought down to tolerable levels. Rehabilitation needs to be instituted as first-line(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)
