Acetabular reconstruction with impacted morcellized cancellous bone autograft and cemented primary total hip arthroplasty: a 10- to 17-year follow-up study

Abstract

During the period 1979 through 1986, 69 acetabular reconstructions in 63 patients were performed with the use of autologous morcellized bone-grafts because of acetabular bone stock loss. Nine cases (10 hips) were lost to follow-up. Eleven patients (12 hips) died <10 years after surgery; none had a revision. The results for the remaining 43 patients (47 hips) were reviewed at an average interval of 12.3 years (range, 10-17 years). No preoperative Harris hip score was available. The average Harris hip score at follow-up was 88 (range, 60-100). Radiographically, all grafts united. One hip developed a deep infection. Three other hips (6%) were revised because of aseptic loosening of the acetabular component. An additional 3 acetabular components were considered radiographic failures. Excluding the infected case, the overall survival rate of these acetabular reconstructions with a revision as endpoint was 94% at an average follow-up of 12.3 years. Reconstruction of acetabular bone stock loss with autologous morcellized bone-grafts is an attractive technique with a good potential for long-term success.
