Abstract

The prevalence of hip osteoarthritis (OA) varies with different regions, and the reasons for this remain unclear. Mild acetabular dysplasia has been considered a risk factor for hip OA, but recent studies have not confirmed this. In Turkey, the prevalence of significant radiographic hip OA, i.e. Kellgren-Lawrence (K-L) grades 3 and 4, is lower than in Western populations. We aimed to investigate the potential effects of radiographic measures of acetabular dysplasia on this discrepancy. Ninety-two Turkish patients (65 males, 27 females) aged 55 and over were studied. Plain supine abdominal radiographs and intravenous pyelographs were evaluated. Centre-edge (CE) angle and acetabular depth (AD) of each hip were measured, and K-L grading was done. The mean CE angles +/- SD of right and left hips were 34+/-7 degrees and 35+/-7 degrees (range 14-52 and 18-50), respectively. The mean AD+/-SD of right and left hips was 13.7+/-3.4 and 13.6+/-3.4 (range 6-23 and 8-25), respectively. Mean CE angle or acetabular depth of the hips with K-L grade 2 did not differ from those with grades 0 and 1. There was no patient with grade 3 or 4. The prevalence of acetabular dysplasia based on a CE angle of
