Abstract
in English, French

Although femoroacetabular impingement (FAI) has recently been considered to be one of the causes of osteoarthritis (OA) of the hip, the exact pathogeneses and incidence of FAI and primary OA are unknown. The purposes of this study were to investigate the causes of hip OA in Japan and to clarify the prevalence of FAI in patients with hip OA. We retrospectively investigated 817 consecutive patients (946 hips) who underwent primary surgery with the diagnosis of OA of the hip. Clinical recordings and preoperative radiographs were evaluated to determine the cause of OA. There were 17 hips who had primary OA, of which six hips were determined to be FAI positive. The remaining 11 cases without FAI had primary OA of unknown aetiology. Our study has revealed that most hip OA cases were caused by developmental dysplasia of the hip. We only found a few cases (0.6%) with FAI in Japan.

Bien que le conflit fémoro acétabulaire (FAI) ait été récemment considéré comme l’une des causes de l’arthrose (OA) de la hanche, la pathogénie exacte et l’incidence du conflit dans l’arthrose primaire restent malgré tout peu connues. Le but de cette étude est d’étudier les causes de l’arthrose de hanche au Japon et de clarifier la prévalence du conflit fémoro acétabulaire chez les patients présentant une telle arthrose. Nous avons respectivement revu 817 patients consécutifs (946 hanches) qui avaient bénéficié d’une intervention primaire chirurgicale pour le diagnostic d’OA de la hanche. Les données cliniques et les radiographies per-opératoires ont également été étudiées pour déterminer les causes de cette arthrose. 17 hanches présentaient une arthrose primaire, 6 sur les 17 étaient secondaires à un conflit fémoro acétabulaire. Pour les 11 hanches restantes, sans conflit fémoro acétabulaire, nous n’avons pu déterminer l’étiologie de l’arthrose. Notre étude révèle que la plupart des arthroses de hanche sont causées par la dysplasie de la hanche. Nous avons trouvé qu’un nombre de cas peu important, 0,6% de conflit fémoro acétabulaire au Japon.
