Computer-assisted orthopaedic surgery slowly is making its way into routine orthopaedic practice. Orthopaedic trauma has long been identified as a potential impact area of this new technology. Early experience with three-dimensional (3D) image-guided surgery was promising, but this particular technique was limited by the inability to update the 3D computer(More)
OBJECTIVES To evaluate the accuracy of computer-assisted sacral screw fixation compared with conventional techniques in the dysmorphic versus normal sacrum. DESIGN Review of a previous study database. SETTING Database of a multinational study with 9 participating trauma centers. PATIENTS The reviewed group included 130 patients, 72 from the navigated(More)
OBJECTIVES Screw navigation techniques with different image guidance [2-dimensional (2D) vs. 3-dimensional (3D) fluoroscopy] were evaluated for acetabular fracture surgery. METHODS Two-dimensional and 3D navigation images were analyzed for visualization of different osseous corridors: supra-acetabular, anterior column, posterior column, and(More)
BACKGROUND The presence of persistent occult hypoperfusion (OH) is associated with higher morbidity and mortality rates after trauma. Early femur fracture fixation in trauma patients with multiple injuries is associated with decreased morbidity and mortality. Association of OH and incidence of postoperative complications after intramedullary (IM) fixation(More)
OBJECTIVE: To examine the effects of oral creatine (Cr) monohydrate supplementation on muscle Cr concentration, body mass, and total body water (TBW), extracellular water (ECW), and intracellular water (ICW) volumes. DESIGN AND SETTING: After an overnight fast, urinary Cr and creatinine concentrations, muscle Cr concentration, body mass, TBW, ECW, and ICW(More)
The first computer-assisted orthopaedic trauma procedures were limited to navigated drill-guide applications, in which the computer was used to predict the trajectory of the drill guide relative to stored radiographic images. By 2003, software for fracture reduction was commercially available. The ability to perform a minimally invasive fracture reduction(More)
OBJECTIVE The current standard treatment of anterior column acetabular fractures includes formal open reduction with internal fixation (ORIF) through a variety of anterior approaches. These approaches have been associated with significant blood loss, infection, lengthy operative times, and neurovascular complications. It therefore seems reasonable to(More)
Traumatic hemipelvectomy is a rare but devastating injury involving complete disruption of the hemipelvis from the pubic symphysis to the sacroiliac joints and often results in death. We present an interesting case of traumatic hemipelvectomy caused by a previously undescribed mechanism of injury in which judicious angiography and aggressive surgical(More)
