ABSTRACT
We conducted a retrospective review of 192 consecutive revision hip arthroplasties with an extended proximal femoral osteotomy performed from 1992 through January 1998. Of these osteotomies, 166 had a minimum of 2 years of clinical and radiographic follow-up (range, 2-7.5 years; average, 3 years, 9 months). All patients had a femoral reconstruction with an extended trochanteric osteotomy and an extensively porous-coated, cementless femoral component. The average age at revision was 65.8 years (range, 26-84 years). Of the 166 osteotomies, 2 nonunions (1.2%) and 1 malunion (0.6%) were identified. Seventeen hips (10.2%) required reoperation. Pain and walking scores improved from a mean of 6.5 preoperatively to 9.8 postoperatively. The extended trochanteric osteotomy heals predictably and enhances the surgeons' ability to address many difficult issues encountered in revision arthroplasty.
