BACKGROUND As a consequence of changes in population demographics, the extremely elderly represent one of the fastest growing groups in Western society. Previous studies have associated advanced age with increased mortality after hip fracture; however, this finding has not been consistent. METHODS The Scottish Hip Fracture Audit is a prospective,(More)
We investigated the relationship between a number of patient and management variables and mortality after surgery for fracture of the hip. Data relating to 18,817 patients were obtained from the Scottish Hip Fracture Audit database. We divided variables into two categories, depending on whether they were case-mix (age; gender; fracture type; pre-fracture(More)
We report gender differences in the epidemiology and outcome after hip fracture from the Scottish Hip Fracture Audit, with data on admission and at 120 days follow-up from 22 orthopaedic units across the country between 1998 and 2005. Outcome measures included early mortality, length of hospital stay, 120-day residence and mobility. A multivariate logistic(More)
Computer-assisted technology allows the accurate location of inaccessible landmarks such as the center of the hip in total hip arthroplasty. Using 7 fresh normal cadaveric hips, we conducted 2 studies. The first study compared iliac (A) vs no iliac (B) tracking. The second study assessed the reliability of the hip center acquisition using the range of hip(More)
PURPOSE To assess the impact of cross-sectional imaging with magnetic resonance (MR) imaging or computed tomography (CT) on clinical decision making for patients with lower back pain (LBP). MATERIALS AND METHODS A randomized controlled before-and-after study was performed in 145 patients who had symptomatic lumbar spinal disorders and had been referred to(More)
Major accident units should be able to apply standard treatment methods to control life threatening haemorrhage within the 'Golden Hour', as recommended by the ATLS guidelines. In this study all 31 major accident units in Scotland were examined to determine their ability to stabilize a pelvic fracture within this period. We found that only eight units could(More)
UNLABELLED Computer-assisted technology creates a new approach to total knee arthroplasty (TKA). The primary purpose of this technology is to improve component placement and soft tissue balance. We asked whether the use of navigation techniques would lead to a narrow range of implant alignment in both coronal and sagittal planes and throughout the(More)
Computer-assisted navigation enables surgeons to measure and assess knee behavior during surgery, allowing real-time monitoring of the knee ranging from extension to flexion. Documenting passive motion before and after total knee arthroplasty (TKA) enabled the authors to analyze knee kinematics. Passive knee motion cannot predict full weight bearing knee(More)
BACKGROUND With recent focus on methicillin-resistant Staphylococcus aureus (MRSA) screening, methicillin-susceptible S. aureus (MSSA) has been overlooked. MSSA infections are costly and debilitating in orthopaedic surgery. METHODS We broadened MRSA screening to include MSSA for elective orthopaedic patients. Preoperative decolonisation was offered if(More)
