Endoprosthetic replacement for malignant bone tumours of the proximal femur

Abstract

Limb salvage procedures are considered the gold standard in the treatment of bone tumours. The use of modular prostheses is one of the options for reconstruction after bone resection in primary tumours and in very restricted cases also in bone metastases. The authors report the results of 27 consecutive cases of proximal femur bone resections and reconstructions with modular prostheses, using the Mutars system. Soft tissue reconstruction and anchorage to the implant was performed using the Trevira tube. The system stem used showed good mechanical resistance, and implant removal was required for infection in only two cases. Functional results were related to the degree of bone resection and muscular sacrifice.
