The imbalance between energy intake and expenditure is the underlying cause of the current obesity and diabetes pandemics. Central to these pathologies is the fat depot: white adipose tissue (WAT) stores excess calories, and brown adipose tissue (BAT) consumes fuel for thermogenesis using tissue-specific uncoupling protein 1 (UCP1). BAT was once thought to(More)
BACKGROUND Despite the recent trend toward internal fixation of distal radial fractures, few randomized trials have examined whether volar plate fixation is superior to other stabilization techniques. The purpose of the present study was to compare (1) open reduction and internal fixation with use of a volar plate and early mobilization with (2)(More)
INTRODUCTION Reported initial success rates after lateral locked plating (LLP) of distal femur fractures have led to more concerning outcomes with reported nonunion rates now ranging from 0 to 21%. Reported factors associated with nonunion include comorbidities such as obesity, age and diabetes. In this study, our goal was to identify patient comorbidities,(More)
BACKGROUND There is a perception that after-hours hip surgery may result in increased complication rates. Surgeon fatigue, decreased availability of support staff, and other logistical factors may play an adverse role. However, there are little data supporting this perception in the hip fracture literature. We present a retrospective study comparing(More)
PURPOSE To compare healing rates of distal radius fractures in patients on bisphosphonate therapy at the time of injury to rates in those not on bisphosphonate therapy. METHODS A total of 196 consecutive patients treated for distal radius fractures were included in this study. Patients currently on bisphosphonate therapy at the time of injury(More)
Hospitals with lower costs are not necessarily superior to those that are more expensive, because the more costly institutions might offer better outcomes. The purpose of this study was to consider prices and outcomes in an integrated model and thereby determine if teaching hospitals are cost-effective for the care of hip fractures. We analyzed the claims(More)
PURPOSE Despite their rising popularity, the health care profession has been slow to embrace social networking sites. These are Web-based initiatives, designed to bring people with common interests or activities under a common umbrella. The purpose of this study is to evaluate social networking patterns among upper extremity patients. METHODS A total of(More)
PURPOSE An inherent deficiency in the understanding of the biomechanics of fractures is the reliance on cadaveric or other nonphysiological injury models resulting from the prohibitive ethical and practical considerations of conducting injury studies in live participants. We describe a novel methodology for studying injury mechanisms using in vivo injury(More)
