Cone femoral prosthesis for osteoarthritis of the hip with femoral dysplasia.

Abstract

PURPOSE: To assess the clinical and radiological outcomes of total hip replacement (THR) using the cone femoral prosthesis. METHODS: Four men and 15 women (26 hips) aged 19 to 78 (mean, 45) years underwent THR for osteoarthritis of the hip with femoral dysplasia using the cone femoral prosthesis. Only 17 patients (24 hips) were available for review. Pain and functional limitation were assessed using the Oxford hip score. Stable fixation by bone ingrowth was defined as no subsidence or radiolucent lines around the prosthesis. RESULTS: The mean follow-up duration was 50 (range, 25-92) months. The mean Oxford hip score improved from 44 (range, 32-54) preoperatively to 17 (range, 12-28) at the l..
