Endoprosthetic replacement for bony metastases

Abstract

A series of 38 patients with long bone metastases treated at the Birmingham Bone Tumour Treatment Service with resection of the metastatic lesion and replacement of the bone defect with an endoprosthesis was reviewed. The majority of cases had pathological fractures due to a massive destructive lesion. Two-thirds of the patients had a solitary metastasis. Metastases from hypernephroma and breast carcinoma accounted for the majority of cases. All the patients were independently mobile after the endoprosthetic replacement and were pain free. The average survival rate after the endoprosthetic replacement was 14.7 months and this varies with the primary tumour. The indications for endoprosthetic replacement for the treatment of long bone metastases are outlined and the results and complications are discussed. It is concluded that endoprosthetic replacement for bony metastases is an effective palliative procedure for a selected group of patients.
