Pelvic reconstruction using saddle prosthesis following limb salvage operation for periacetabular tumour.

Abstract

PURPOSE: To assess the clinical results of pelvic reconstruction using a saddle prosthesis following limb salvage operation for periacetabular tumour. METHODS: 12 patients with sarcoma and 4 with metastasis involving the pelvis were treated using the saddle prosthesis between 1995 and 2003 inclusive. Wide pelvic resection was performed for all patients with sarcoma and one with a metastatic lesion; intralesional excision of the acetabulum was undertaken for the remaining 3 patients with metastatic lesions.
