Abstract
Two matched groups of 29 patients underwent hydroxyapatite-coated non-cemented total hip replacement. One group was started on immediate protected-weight-bearing walking and the other group was started on immediate full-weight-bearing walking. They were followed up regularly for 2 years. They were assessed with Harris hip score clinically and Engh's criteria of osteo-integration radiographically. No difference was found between the two groups. All patients had excellent clinical outcome after hip replacement, and all femoral stems were stable radiographically. Patients can walk with full weight bearing safely immediate after hydroxyapatite-coated non-cemented total hip replacement.
Résumé
Deux groupes appairés de 29 malades ont eu une arthroplastie totale de la hanche avec une prothèse non cimenté, recouverte d'hydroxyapatite . Un groupe a repris la marche immédiatement avec appui protégé et l'autre groupe avec appui complet. Ils ont été suivis pendant 2 années régulièrement. Ils ont été étudiés avec le score clinique de Harris et les critères radiographique d'Engh pour l'ostéointégration. Aucune différence n'a été trouvée entre les 2 groupes. Tous les malades ont eu un excellent résultat et toutes les tiges fémorales étaient stables radiographiquement. Les malades peuvent marcher avec appui complet immédiat après une prothèse de hanche sans ciment recouverte d'hydroxyapatite.
