Abstract.

We prospectively studied 250 patients with a proximal hydroxyapatite coated hip prosthesis. The follow-up period was 5 years. All components showed osseointegration except for one deep infection. The morphology of bone remodeling with either endosteal bone formation or periosteal bone formation was dependent on the way the stem filled the medullary canal. No linear or distal osteolysis around the stems was observed.

Résumé.

250 patients avec une prothèse de la hanche revêtue d' hydroxyapatite ont été étudiés avec un suivi de 5 années. Tous les composants ont montré une ostéointégration à l'exception d'un cas avec une infection profonde. La formation osseuse endostée ou periostée était dépendante du remplissage du canal médullaire par la tige. Aucune ostéolyse autour des tiges n'a été observée.
