Abstract
in English, French

The objective of this study was to investigate the relation between acetabular dysplasia (AD) of the hip and risk for development of hip osteoarthritis (OA) in a Sámi population with very high prevalence of AD (38%). A population-based survey was conducted in a main Sámi area in Norway. A total of 315 middle-aged subjects were examined clinically and radiologically and were regarded as a random sample of 836 responders from a general health survey. The results demonstrated that 6.8% of the Sámi population had OA. The logistic regression analyses did not show a significant association between AD and OA. Only age had a statistically significant influence on OA. In this middle-aged Sámi population, there is no evidence for the influence of AD on the development of hip OA.

Objectif: de façon à évaluer les relations entre la dysplasie acétabulaire (AD) de la hanche et le risque d’évolution vers une coxarthrose (OA), la population Sami qui présente un haut niveau de dysplasie de la hanche (38%) a été analysée. Méthode: la région Sami est une région de Norvège. 315 sujets d’âge moyen ont été examinés cliniquement et radiologiquement sur 836 questionnaires généraux de santé. Résultats: 6,8% de la population de la région Sami présentait une coxarthrose. L’étude avec courbe de régression a montré que le facteur statistiquement significatif influençant l’évolution vers une coxarthrose était l’âge. En conclusion: dans la population d’âge moyen de la région de Sami, il n’y a pas à l’évidence d’influence de la dysplasie de hanche sur le développement de la coxarthrose.
