The operative management of pelvic ring fractures and dislocations is difficult. Posterior pelvic ring disruptions are often associated with severe soft-tissue injuries and high infection rates. Percutaneous iliosacral screw fixation of the posterior pelvis has become popular with improved fluoroscopic imaging techniques. The percutaneous iliosacral screw(More)
OBJECTIVE To summarize the complications and early clinical results of 123 distal femur fractures treated with the Less Invasive Stabilization System (LISS; Synthes, Paoli, PA). DESIGN Retrospective analysis of prospectively enrolled patients. SETTING Two academic level I trauma centers. SUBJECTS AND PARTICIPANTS One hundred nineteen consecutive(More)
BACKGROUND There is no consensus on the best treatment for periprosthetic supracondylar fracture. MATERIAL AND METHODS We systematically summarized and compared results of different fixation techniques in the management of acute distal femur fractures above a total knee arthroplasty (TKA). Several databases were searched (Medline, Cochrane library, OTA(More)
BACKGROUND The use of recombinant human bone morphogenetic protein-2 (rhBMP-2) to improve the healing of open tibial shaft fractures has been the focus of two prospective clinical studies. The objective of the current study was to perform a subgroup analysis of the combined data from these studies. METHODS Two prospective, randomized clinical studies were(More)
BACKGROUND Fractures of the scapula account for 3% to 5% of all fractures of the shoulder girdle and make up less than 1% of all broken bones. Scapula fractures typically occur after high-energy trauma, and approximately 90% of the patients have associated injuries. OBJECTIVE (1) To determine the incidences of nonoperative and operative treatment of(More)
OBJECTIVE To summarize the surgical experience and clinical results of the first 89 fractures of the proximal tibia treated with the Less Invasive Stabilization System (LISS; Synthes, Paoli, PA). DESIGN Retrospective analysis of prospectively enrolled patients into a database. SETTING Academic level I trauma center. SUBJECTS/PARTICIPANTS Eighty-seven(More)
BACKGROUND The incidence of distal femur fractures is approximately 37 per 100,000 person-years. Typically, distal femur fractures are caused by a high-energy injury mechanism in young men or a low-energy mechanism in elderly women. Managing these fractures can be a challenging task. Most surgeons agree that distal femur fractures need to be treated(More)
We have studied the effect of shortening of the femoral neck and varus collapse on the functional capacity and quality of life of patients who had undergone fixation of an isolated intracapsular fracture of the hip with cancellous screws. After screening 660 patients at four university medical centres, 70 patients with a mean age of 71 years (20 to 90) met(More)
Supracondylar femoral fractures above total knee arthroplasty remain a treatment challenge. Complication rates as high as 30% are associated with both nonoperative and operative treatment. Conventional plate fixation and rigid intramedullary nail fixation has improved the treatment of these fractures. However, problems still exist in the setting of a short(More)
OBJECTIVE To evaluate the stability of the retrograde intramedullary nail (IMN), angled blade plate (ABP), and a locked internal fixator (Less Invasive Stabilization System [LISS], Synthes, Paoli, PA) for internal fixation of distal femur fractures. DESIGN Destructive biomechanical testing of matched pairs of fresh-frozen human cadaveric bone-implant(More)
