Abstract

This study was based on data from the Finnish Arthroplasty Register. From 1990 to 1999, 33,154 primary hip arthroplasties were performed in Finland. Only periprosthetic fractures treated by a revision arthroplasty were registered. The six most used femoral components were compared using survival analysis and Cox's regression model. The incidence of periprosthetic fractures was calculated separately for the years 1990–1994 and 1995–1999. The incidence in the first period was greater than in the latter. Survival analysis and Cox's regression model showed that gender, prosthesis type and age were of no significance as risk factors for periprosthetic fractures.

Résumé

Cette étude a été basée sur les données du Registre finlandais des Arthroplasties. De 1990 à 1999 33.154 arthroplasties totales de la hanche ont été exécutées en Finlande. Seulement les fractures periprothétiques traitées par une arthroplastie de révision ont été enregistrées. Les six composants fémoraux le plus utilisés ont été comparés en utilisant l' analyse de la survie et le modèle de régression de Cox. La fréquence des fractures périprothetiques a été calculée séparément pour les années 1990–1994 et 1995 –1999 et elle était plus élevée dans la première période que dans la deuxième. L'analyse de la survie et le modèle de Cox ont montré que le sexe, le type de prothèse et l'âge n'étaient d'aucune signification comme facteur de risque pour ces fractures périprotèthiques.
