The use of a total femoral prosthesis can offer a realistic alternative to amputation or disarticulation. The limited indications for such a prosthesis in the surgical management of primary bone tumours and pathological fractures still exist. In this specialised clinic there is an increased need to replace the entire femur where repeated procedures have failed, from loss of bone stock with infection or because of non-union in the presence of a prosthesis. Over the past eight years, four basic models have been developed. The most recent designs allow for the preservation of non-involved bone or for stable support where there is complete acetabular destruction.

Eleven patients underwent disarticulation for infected arthroplasty of the hip. Exchange total hip arthroplasty or conversion to a Girdlestone excision arthroplasty had been undertaken previously an average of 2.9 times. The indications for disarticulation were as a life-saving measure, or as a result of severe infection of soft tissue and bone, loss of bone stock, or vascular injury. While the indications for this drastic operation were highly individual, there were instances where disarticulation could have been avoided if repeated exchange operations had been eschewed in deference to a Girdlestone procedure.
