Fatigue testing of a proximal femoral hip component.
The Gothenburg Osseointegrated Titanium (GOT) implant is a novel total hip replacement including a metaphyseal loading proximal femoral component fixed in the retained femoral neck. Endurance testing was performed under conditions analogous to ISO 7206-4: 1989. The cement-free implant is not fixed distally within the intramedullary canal, so distal embedding (as specified in the standard) would...
متن کاملProximal femoral allografts in revision hip arthroplasty.
We followed prospectively 69 patients with 78 proximal femoral allografts performed for revision of total hip arthroplasty for an average of 36 months (range 29 to 68). Large fragment proximal femoral allografts and cortical strut allografts were successful in 85%. Grafts smaller than 3 cm in length (calcar grafts) were clinically successful in 81%, but 50% underwent significant radiographic re...
متن کاملProximal femoral geometry and hip fractures.
There is increasing evidence that proximal femoral geometry has an important role in the aetiology of hip fractures. We performed a simple radiological study to investigate the relationship between proximal femoral geometry and intracapsular and extracapsular fractures of the proximal femur. Measurements of proximal femoral geometry were made on pelvic radiographs on the contralateral hip of 50...
متن کاملRevision total hip arthroplasty in patients with extensive proximal femoral bone loss using a fluted tapered modular femoral component.
Revision total hip arthroplasty (THA) is challenging when there is severe loss of bone in the proximal femur. The purpose of this study was to evaluate the clinical and radiographic outcomes of revision THA in patients with severe proximal femoral bone loss treated with a fluted, tapered, modular femoral component. Between January 1998 and December 2004, 92 revision THAs were performed in 92 pa...
متن کاملFemoral Component Revision of Total Hip Arthroplasty.
Modern primary total hip arthroplasty (THA) is among the most successful operations in medicine. It has been a consistently effective treatment for end-stage osteoarthritis of the hip. With the increasing number of primary THA procedures being performed and the decreasing age of patients undergoing the procedure, there is an inevitable associated increase in revision burden for arthroplasty sur...
