An alternative location for placement of half-pins during pelvic external fixation is the dense supra-acetabular bone in the region of the anterior-inferior iliac spine. Although these fixators have gained popularity, to the authors' knowledge there are no studies evaluating the potential anatomic risks of placement of half-pins in this area; no safe(More)
We previously have shown that experimental fractures exposed to ciprofloxacin have diminished fracture healing. The purpose of this study was to assess the effect of levofloxacin and trovafloxacin on experimental fracture healing to test the hypothesis that diminished fracture healing is a quinolone class effect. Sixty-one male Wistar rats were divided into(More)
Seventy-three patients (84 hips) 50 years or younger were treated with primary total hip arthroplasty using the Harris-Galante uncemented acetabular component. At a median followup of 10 years, there were seven acetabular metal shell revisions: five for osteolysis and one each for aseptic loosening and dislocation. There were 10 polyethylene exchanges(More)
BACKGROUND Hip arthroplasty for the treatment of nonunion at the site of a femoral neck fracture has provided good short-term results. The purpose of the present study was to evaluate the long-term results and complications of total hip arthroplasty for the treatment of femoral neck nonunion. METHODS The records of ninety-nine patients who had been(More)
Blood flow to canine saphenous nerve grafts either in contact with a healthy soft-tissue bed or isolated from the soft-tissue bed by entubulation was quantitated at 3, 7, 14, and 28 days after surgery with radionuclide-labeled microspheres and evaluated histomorphometrically. At 3 days there was no statistical difference between the 2 techniques in regard(More)
