Bone transport is based on the principle of distraction osteogenesis described by Ilizarov and is a consecrated method for the treatment of segmental bone defects. One of its most problematic and, paradoxically, least studied aspects is the consolidation of the docking site. We studied histologically the ossification of the docking site and regenerate to(More)
BACKGROUND Premature closure of the proximal femoral growth plate results in coxa brevis, which usually is associated with insufficiency of the hip abductors. Distal and lateral transfer of the greater trochanter sometimes is recommended to correct this problem. Most of what is known arises from studies of children and adolescents. QUESTIONS/PURPOSES We(More)
The superior gluteal nerve may be damaged during total hip arthroplasty. We prospectively studied 40 patients who had total hip arthroplasties using the Hardinge direct lateral approach to the hip to determine any correlation between superior gluteal nerve damage and abductor function. We used the Trendelenburg test to clinically evaluate abductor function(More)
OBJECTIVE The purpose of this series was to determine the frequency of abductor mechanism avulsion by sonography after total hip arthroplasty with the Hardinge approach (J Bone Joint Surg Br 1982; 64:17-19) and its relationship to the presence of insufficiency of this musculature in the postoperative period. METHODS Thirty-four consecutive patients were(More)
OBJECTIVE To compare the occurrence of thrombophilic disorders in patients with idiopathic osteonecrosis of the femoral head and patients with secondary osteonecrosis of the femoral head. METHODS Twenty-four consecutive patients were enrolled, with eight of them presenting idiopathic osteonecrosis and 16 presenting secondary osteonecrosis. The tests for(More)
The aim of this investigation was to assess the diagnostic accuracy of intraoperative cultures for the early identification of patients who are at risk of infection after primary total hip arthroplasty.Four or six swabs were obtained immediately before the wound closure in 263 primary total hip replacements. Patients with a maximum of one positive culture(More)
We report a case of bilateral fracturing of the femoral neck in a patient with renal osteodystrophy who was treated by means of osteosynthesis. In this type of patient, there is a need to remain watchful for the possibility of occurrences of spontaneous fracturing of the femoral neck, even if the initial radiographic examination is normal.
OBJECTIVE To evaluate the efficacy and safety of unfractionated heparin associated with mechanical prophylaxis as a method for preventing venous thromboembolism in hip arthroplasty. METHOD We retrospectively reviewed the records of 181 hip arthroplasties out of 216 consecutive cases performed over a period of 39 months in our hospital. We excluded 35(More)
OBJECTIVE To determine intra and interobserver agreement of the grading system for femoral cementation in hip arthroplasty proposed by Barrack. METHODS Immediate anteroposterior and lateral postoperative radiographs of 55 primary total hip arthroplasties were assessed by two observers familiar with the use of this grading system. The assessments were(More)
The aseptic loosening rate of the Mayo hip prosthesis femoral stem was determined in a 44 patient (52 hips) series, by comparing preoperative and postoperative clinical and radiographic parameters, over a minimal 5-year postoperative period. Loosening was obvious before five years in four hips (7.6%), while the stem was considered stable in the remaining 48(More)
