Acetabular dysplasia as an aetiological factor in development of hip osteoarthritis

Abstract

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. © 2008 Springer-Verlag.
