Femoral replacement for salvage of periprosthetic fracture around a total hip replacement.

Abstract

A total of 20 patients with a mean age of 72 (range: 36-91) were managed with replacement of the proximal (15) or total (5) femur for salvage of a periprosthetic femoral fracture with bone loss. A mean 12.5 years had elapsed between primary total hip replacement and surgery and the mean follow-up was 48 months (range: 12-116 months). Clinical outcome was assessed using the Toronto Extremity Salvage Score (mean: 68, range: 32-98) and Short Form 36 (SF-36; mean Physical Component Score (PCS): 53, range: 44-62; mean Mental Component Score (MCS): 51, range: 41-64). No prostheses were radiologically loose. There were six major complications; three patients suffered a postoperative dislocation; two patients had persistent deep infection (present preoperatively); and one patient suffered a fracture of their femur distal to the femoral stem of a proximal femoral replacement. Endoprosthetic replacement of the femur is a reasonable salvage option for patients with periprosthetic fracture and bone loss, with good clinical results. It allows immediate weight bearing and does not rely on bony union for success.
