AbstractWe reviewed 27 cementless primary total hip replacements in patients with osteoarthrosis secondary to congenital dysplasia of the hip. Autogenous bone grafting was used as augmentation. On average the follow-up period was 9 years. Two hips were revised and three acetabular components were considered loose. In hips with loose cups the average graft coverage was significantly greater than in stable hips. The use of a cementless acetabular component is encouraging for reconstruction, although extensive grafting should be avoided. Our study suggests that cementless reconstruction in dysplastic hips yields a satisfactory outcome.
RsumNous avons examin 27 arthroplasties sans ciment chez les patients avec arthrose secondaire une dysplasie congnitale de la hanche. Une greffe dos autogne a t utilis comme augmentation. La priode moyenne de suivi a t 9 annes. 2 hanches ont t rvises et 3 composants acetabulaires ont t descells. Dans la hanche ayant les composants descells, la couverture moyenne de la greffe tait significativement suprieure celle des hanches stables. Lutilisation des composants acetabulaires sans ciment est encourage pour la reconstruction, bien que la greffe massive doive tre vite. Notre tude suggre que larthroplastie sans ciment avec greffe autogne pour les hanches dysplasiques est associe un rsultat satisfaisant.
