Abstract
We retrospectively evaluated 17 hips in 16 patients who underwent a periacetabular osteotomy for the treatment of dysplastic hip with Perthes-like deformities. These residual deformities were graded using the Stulberg classification system. There were three class II hips, 11 class III hips and three class IV hips preoperatively. The average age of the patients at surgery was 36.9 years and the average follow-up was 6.6 years. The average Harris hip score significantly improved from the preoperative value of 68.2 points to 91.1 points postoperatively. The average postoperative range of motion in all directions did not change significantly from the preoperative value. The average postoperative Harris hip score of class IV hips was smaller than that of the class II or class III hips. The standard radiographic evaluations also showed significant improvements postoperatively. Periacetabular osteotomy without combined femoral osteotomies, as a treatment for patients with Perthes-like deformities, produced good clinical and radiographic results.
Résumé
Nous avons évalué de façon rétrospective 17 hanches chez 16 patients qui ont bénéficié d’une ostéotomie périacétabulaire pour le traitement de hanche dysplasiques avec des déformations de type Perthes. Les déformations résiduelles ont été classées selon la méthode de Stulberg. Il y avait en préopératoire 3 hanches de type II, 11 de type III et 3 de type IV. L’âge moyen des patients au moment de l’intervention était de 36.9 ans et le suivi moyen de 6.6 ans. Le score moyen de Harris a été amélioré de façon significative passant de 68.2 points à 91.1 points en post opératoire. La mobilité post opératoire n’a pas été affectée de façon significative par rapport à la mobilité préopératoire. Le score de Harris moyen post opératoire des hanches de type IV est légèrement inférieur à ceux de type II ou III. Les radiographies standards ont montré une amélioration significative en post opératoire. L’ostéotomie périacétabulaire sans qu’elle soit associée à une ostéotomie fémorale est un traitement qui donne donne de bons résultats tant sur le plan clinique que radiographique sur des hanches déformées de type Perthes.
