Abstract
in English, French

The aim of the study was to analyse the survivorship of 60 total hip arthroplasties using the cementless Lord prosthesis in 51 patients with inflammatory joint disease. Patients were operated on between the years 1985 and 1988. The mean follow-up time was 13.8 (4.0-18.6) years. During the follow-up, one deep infection was encountered, and seven patients died of causes unrelated to the hip replacement. Revision surgery or death of the patient was used as an end point. The overall survival was 88.1% [95% confidence interval (CI) 76.6-94.1] for the stem, and 64.3% (95% CI 50.6-75.1) for the cup at 15 years. Causes for revision surgery were loosening of the cup in 17 hips, loosening of both components in five hips, and one deep infection.

Le but de cette étude est d’analyser la courbe de survie de 60 prothèses totales de hanche chez 51 patients présentant une pathologie inflammatoire, les malades ayant été prothèsés avec une prothèse sans ciment de type Lord. Les patients ont été opérés entre 1985 et 1988. La moyenne de suivi a été de 13,8 ans (4 à 18,6 ans). Durant cette période une seule infection profonde a été rencontrée et 7 patients sont décédés sans relation avec leurs prothèses. La révision de la prothèse où la mort du patient a été utilisée comme terme pour l’utilisation de la courbe de survie, le taux de survie a été de 88,1% (95% d’intervalle de confiance 76,6 à 94,1) pour la pièce fémorale et 64,3% (95% d’intervalle de confiance 50,6 à 75,1) pour la cupule à 15 ans. Les causes de révision ont été le descellement de la cupule dans 17 hanches et le descellement des deux composants dans 5 hanches avec une seule infection profonde.

However, there are marked radiolucent lines around the proximal part of the femoral component.
