It has been shown that after a critical point in the moult cycle of a cockroach, wound healing can occur but regeneration of pattern does not take place until the following intermoult period. Leg removal after the critical point is used to separate the processes of wound healing and leg regeneration. This permits the study of patterns of cell division resulting from wound healing to be distingu...

A 13-year-old boy sustained an avulsion fracture of the left greater trochanter eight months after surgical stabilisation of a slipped capital femoral epiphysis on the same side. In this specific case, avulsion of the greater trochanter after slipping of the capital femoral epiphysis may have been facilitated by weakening of the trochanteric physis.

AIMS The severe form of coxa vara, the 'shepherd's crook deformity', is always a consequence of a locally extensive form of polyostotic fibrous dysplasia (or McCune-Albright syndrome). Treatment of this deformity is a challenge. The soft bone does not tolerate any implant that depends on the stability of the cortical bone (like plates or external fixators). Intramedullary nails are the most app...

BACKGROUND: The modified Dall approach is a modified anterolateral approach with osteotomy of the anterior part of the greater trochanter. OBJECTIVES: We aimed to evaluate the adequacy of the modified Dall approach by measuring leg length discrepancy and evaluating offset discrepancy using postoperative radiographs. METHODS: Of 103 cases of total hip arthroplasty (THA), 22 patients (mean age, 6...

OBJECTIVES To study the vascularity and bone metabolism of the femoral head/neck following hip resurfacing arthroplasty, and to use these results to compare the posterior and the trochanteric-flip approaches. METHODS In our previous work, we reported changes to intra-operative blood flow during hip resurfacing arthroplasty comparing two surgical approaches. In this study, we report the vascul...

This review deals with thirty-eight patients with tuberculosis of the greater trochanter treated throughout or partly at the Royal National Orthopaedic Hospital during the last twenty-five years. In thirty-five cases the diagnosis was confirmed by culture, histology or guinea)ig illoculation. In the other three cases we considered that tile clinical and radiographic findings justified their inc...

Ischiofemoral impingement is a newly recognized cause of extra-articular hip pain, and is caused by contact between the lesser trochanter and ischium. Surgical intervention has been proven successful for patients with persistent pain and disability after failure of nonoperative management. This technique article provides a reliable method for endoscopic lesser trochanter osteoplasty using an an...

We present the long-term clinical and radiological results of a series of 168 young patients with unilateral Perthes disease who were treated in our department between 1989 and 1997, using a combined osteotomy in the longitudinal and horizontal axis of the proximal femur and elongation of the femoral neck. Surgical treatment was undertaken for any group II (Catterall's classification) patient, ...

This article presents an anterior, minimally invasive surgical approach to the hip joint, aligned along an inter-nervous plane. Positioning in lateral decubitus position on a regular operation table obviates the need for a special orthopedic or fracture table. Traction is not applied. Most of the instruments used for this procedure are standard instruments for reaming of the acetabulum and posi...

necessitates immobihisation in a plaster spica for several weeks. In order to avoid this, and to allow early activity, various forms of internal fixation have been used. Most of these consist of some form of modified “ blade plate “ which is screwed to the femoral shaft. They all have disadvantages. The length and the extent of the operation are increased, and fixing the plate to the femur tend...
