成人髋臼发育不良的临床调查分析

Clinical investigation and analysis of dysplasia of the acetabulum in adults

目的 :了解成人髋臼发育不良的发病率 ,以及与骨性关节炎的关系。 方法 :本组共收集 10 80例成人站立位骨盆 X线前后位片 ,采用 Wiberg法测量髋关节 CE角 ,Sharp法测量髋臼角。 结果 :10 80例中 2 5例 46个髋臼发育不良 ,其中男 5例 9个髋臼 ,女 2 0例 37个髋臼。 结论 :本组成人髋臼发育不良发病率为 2 .3% ,女性发病率为 3.7% ,男性发病率为 0 .9% ,男∶女为 1∶ 4,女性发病率明显高于男性。髋臼发育不良与骨性关节炎密切相关。

Objectives: The purpose of this study was to know the incidence of acetabular dysplasia in adults and the acetabular dysplasia related osteoarthritis. Methods: One thousand and eighty adult antero-posterior pelvic roentgenograms were reviewed retrospectively. The CE angles of hip joints were measured using Wibergs method and the acetabular angles were measured using Sharps method. Results: There were 46 dysplastic acetabula in 25 patients from 1 080 cases, 9 dysplastic acetabula in 5 men, and 37 dysplastic acetabula in 20 women. Conclusions:The incidence of acetabular dysplasia in 1 080 adults is about 2.3%, about 3.7% in women and about 0.9% in men incidence rate of Man ∶ Female were 1 ∶ 4. The incidence of acetabular dysplasia in women was higher than men. Osteoarthritis might be related with the acetabular dysplasia.
