目的 探讨CT对成人髋臼结构不良的诊断价值。方法 对 2 8例髋臼结构不良患者的 5 6个髋关节CT资料进行回顾性分析。结果 成人髋臼结构不良的CT影像中 ,75 .0 %髋臼表现有前部发育不良 ,而髋臼前后部均发育不良 ( 14 .4% )和臼窝形态异常 ( 14 .9% )者少见 ,5 7.1%髋臼顶部有发育不良。此外 ,CT发现继发性骨关节病和股骨头缺血坏死分别为 91.1%和 16 .1% ,均高于平片所见。结论 CT有助于全面了解髋臼发育状况及其与股骨头相互适应情况 ;确定髋臼结构不良的基本类型 ;早期发现继发性骨关节病和股骨头缺血坏死及评估髋关节病变的严重程度。
Objective To investigate the diagnostic value of CT on the malformation of adult acetabulum. Methods A retrospective analysis was performed on 56 CT data of 28 patients with poor acetabular structures. Results 75% of the acetabulum showed anterior dysplasia in the adult with poor acetabular structure, while both anterior and posterior acetabular dysplasia (14.4%) and abnormality of the acetabulum (14.9%) Rare, 5 7.1% Top of acetabulum dysplasia. In addition, CT found that secondary osteoarthrosis and avascular necrosis were 91.1% and 16.1%, both higher than plain film. Conclusion CT helps to fully understand the development of the acetabulum and its mutual adaptation with the femoral head; to determine the basic types of acetabular malformation; early detection of secondary osteoarthritis and avascular necrosis and assess the severity of hip joint disease degree.
