TOTAL HIP ARTHROPLASTY AFTER FEMORAL OSTEOTOMY

Purpose: Total hip arthroplasty after failure of femoral osteotomy raises high risk of complications. Outcome has been controversial. The purpose of this retrospective analysis was to evaluate the difficulties and results.Material and methods: Between March 1974 and January 1995, 68 patients (82 hips), 51 women and 17 men, mean age 59±11.5 years (32–84) underwent surgery. Initial indications were mainly acetabular and/or femoral dysplasia (n=47 hips) or congenital dislocation (n=21 hips). Mean time between osteotomy and arthroplasty was 13.8±8.4 years (10 months-45 years). We used cemented titanium femoral stems (Ceraver Ostal) with an alumina (n=66) or polyethylene (n=16) cup. An alumina-alumina bearing was used in 67 hips (81%). Functional outcome was assessed with the Postel-Merle-d’Aubligne score. Radiological analysis searched for lucent lines and signs of wear. The actuarial survival was determined.Results: One patient (1 hip) was lost to follow-up. Thirteen patients (14 hips) died of intercurrent c...
