Abstract

The extended proximal femoral osteotomy is becoming increasingly popular in revision total hip replacement. Our study was done to determine the femoral stem length required for stable fixation of a cementless femoral component after an extended proximal femoral osteotomy. Three lengths of the S-ROM femoral stem were implanted in paired cadaver femora and tested under torsional and axial loads. The results indicate that the standard (160 mm) and long (215 mm) stems do not provide adequate torsional stability after a 160 mm extended proximal femoral osteotomy. The extra-long (255 to 315 mm) stems provided significantly greater stability, suggesting that the extended proximal femoral osteotomy may need to be bypassed by more than 2 cortical diameters, especially when a flexible stem such as the S-ROM is used.
