  1. Hip osteoarthritis and dysplasia in Chinese men.

    Article - En anglais

    Objective

    To estimate the prevalence of hip osteoarthritis (OA hip) and hip dysplasia in a sample of Hong Kong men who were unselected with respect to hip symptoms.

    Method-The postmicturition films of 999 men aged 60-75 years, consecutive attenders for intravenous urography between 1987 and 1990 at a regional hospital, were reviewed.

    OA hip was diagnosed as the occurrence of two or more features of OA using a modified version of the Kellgren and Lawrence scale, or a minimal joint space of 1.5 mm or less.

    Hip dysplasia was defined as a centre-edge angle of less than 25°, or an acetabular depth of less than 9 mm.

    The results were compared with British data obtained by similar methods.

    Result-In the Hong Kong sample, the proportion of men with two or more features of osteoarthritis in at least one hip was about 50% that of the men in the British study (5.4% and 11.0%, respectively).

    Severe joint space narrowing (of 1.5 mm or less) occurred in 0.7% of the hips in Hong Kong men, compared with 2% in the British men.

    The proportion of hips with centre-edge angles less than 25° was 4.5% in Hong Kong, compared with 3.6% in Britain, and the prevalence of shallow acetabular depth was greater in Chinese (14.5%) than in the British (2.1%). Radiographic measures of hip dysplasia were not associated with minimal joint space.

    Conclusion-Our results have confirmed the lower prevalence of radiographic hip osteoarthritis in Hong Kong men compared with British men.
