Patients with acetabular dysplasia commonly undergo peri-acetabular osteotomy after skeletal maturity to reduce the risk of the late development of osteoarthritis. Several studies have suggested that deformity of the femoral head influences the long-term outcome. We radiologically examined 224 hips in 112 patients with acetabular dysplasia and early-stage osteoarthritis. There were 103 women and nine men with a mean age of 37.6 years (18 to 49). A total of 201 hips were placed in the acetabular dysplasia group and 23 in a normal group. The centre-edge angle and acetabular head index were significantly smaller (both p < 0.001), and the acetabular angle, acetabular roof angle and roundness index were significantly greater in the acetabular dysplasia group than those in the normal group (all p < 0.001). There were significant correlations between the roundness index and other parameters. Femoral head shape may be influenced by the severity of the acetabular dysplasia.
髋臼发育不良患者在骨骼成熟后常行髋臼周围截骨术，以降低晚期发生骨关节炎的风险。一些研究表明股骨头畸形会影响长期预后。我们对 112 例髋臼发育不良伴早期骨关节炎患者的 224 髋进行了影像学检查，其中女性 103 例，男性 9 例，平均年龄 37.6 岁（18 岁至 49 岁）。共有 201 髋位于髋臼发育不良组，23 髋位于正常组。髋臼发育不良组的中心边缘角和髋臼头指数明显较小（均 p < 0.001），髋臼角、髋臼顶角度和髋臼圆度指数明显大于正常组（均 p < 0.001）。髋臼圆度指数与其他参数之间存在显著相关性。股骨头的形状可能受髋臼发育不良严重程度的影响。
