OBJECTIVE To determine the incidence and severity of tibial malrotation following reamed intramedullary nail fixation as measured by computerized tomography and to determine the repeatability of computed tomography measurement in the assessment of rotational malreduction. DESIGN Prospective cohort. SETTINGS Level 1 trauma center. PARTICIPANTS(More)
We randomised prospectively 44 patients with fractures of the shaft of the humerus to open reduction and internal fixation by either an intramedullary nail (IMN) or a dynamic compression plate (DCP). Patients were followed up for a minimum of six months. There were no significant differences in the function of the shoulder and elbow, as determined by the(More)
This study tested different methods of internal fixation of a symphyseal disruption, in comparison with the mechanics of the intact pelvis. Unembalmed cadaveric pelves were tested in simulated bilateral stance in a servohydraulic materials-testing machine. Motion of the superior and inferior pubic symphysis, and at two levels of the posterior sacroiliac(More)
A marked discrepancy exists in the reported mortality rates in patients with open pelvic fractures, ranging from 4.8% to 50%. A retrospective review of patients with open pelvic fractures was performed at three centers. Thirty-nine patients with open pelvic fractures were identified; the average age was 32. The average injury-severity score was 29 (13-75).(More)
Double-level noncontiguous spinal injury is a more common occurrence than generally appreciated. A large number of these patients have neurological injury. Because these injuries occur in patients who meet the criteria for categorization as multiple trauma patients, we feel that a complete radiographic survey of the spine must be accomplished in the(More)
Surgical dislocation of the hip in the treatment of acetabular fractures allows the femoral head to be safely displaced from the acetabulum. This permits full intra-articular acetabular and femoral inspection for the evaluation and potential treatment of cartilage lesions of the labrum and femoral head, reduction of the fracture under direct vision and(More)
This study compares the relative strengths of iliosacral lag screws and transiliac bars in the fixation of vertically unstable pelvic injuries with sacral fractures. A vertical sacral fracture was artificially induced by vertical loading in eight pelvises from cadavers, which were then fixed with two 6.5 mm iliosacral lag screws or two 6.4 mm transiliac(More)
Control of rotation after intramedullary fixation of the humeral shaft has been observed to vary clinically. Two of the newer intramedullary nails specifically designed for the humerus were tested. Transverse and spiral fractures were created in 35 fresh-frozen cadaveric humeri. The constructs were tested in a materials testing system to evaluate in vitro(More)
The cases of 60 patients with 63 open femoral fractures treated by primary reamed intramedullary nailing were retrospectively reviewed. Twenty-two were classified as Type I open fractures, 26 as Type II and 15 as Type III open fractures by Gustilo's classification. All fractures were treated by wound debridement followed by immediate reamed intramedullary(More)
Although iliosacral lag screws are an established technique for fixation of sacroiliac joint dislocation and sacral fractures, there is a paucity of data on the relative strength of fixation of screws in the sacral ala and body. The purpose of this study was to quantify and compare the extraction strength of cancellous screws in the sacral ala and body.(More)
