Traditionally, Lisfranc fracture dislocations have been treated with transarticular screw fixation. A more recent development has been the use of dorsal bridging plates. The aim of the present study was to compare the radiologic outcomes for these 2 methods. Currently, no data comparing the outcomes of these 2 treatment options have been reported. A total(More)
BACKGROUND There is an increasing body of literature suggesting that the use of patient-specific instrumentation (PSI) in total shoulder arthroplasty (TSA) results in improved positioning of the glenoid component. The aim of this in vivo study was to assess the accuracy of PSI of the glenoid component in TSA in a consecutive series at a single center. (More)
OBJECTIVE To identify whether transarticular screws, dorsal bridging plates or a combination of the 2 result in the best functional outcome after Lisfranc injury. DESIGN Case series. SETTING Level one trauma center. PATIENTS Fifty patients who underwent surgical fixation of Lisfranc injuries over a 6-year period were retrospectively reviewed. (More)
Objectives: To evaluate the accuracy of computed tomography (CT) in the management of primary aldosteronism by comparing the concordance between CT and adrenal venous sampling (AVS), and the feasibility of AVS as a standard component in the diagnostic workup. Methods: From January 2009 to December 2012, 44 instances of AVS performed in 39 patients in Kwong(More)
AIM The classification of a Lisfranc injury has conventionally been based around Myerson's system. The aims of this study were to review whether a novel classification system based on sagittal displacement of the tarsometatarsal joint and breadth of injury as determined by a columnar theory was associated with functional outcomes and thus had a greater(More)
Musculoskeletal trauma to the foot is a common presentation to EDs. A Lisfranc fracture dislocation involves injury to the bony and soft tissue structures of the tarsometatarsal joint. While it is most commonly seen post high velocity trauma, it can also present post minor trauma. It is also misdiagnosed in approximately 20% of cases. These Lisfranc(More)
