摘　　要：目的 :提高对强直性脊柱炎髋关节病变的认识。材料和方法 :回顾性分析 12例经临床诊断及治疗的强直性脊柱炎髋关节病变的CT表现。结果 :CT表现为股骨头骨质疏松内密度不均 (n =6)。股骨头及髋臼虫蚀状骨质破坏 ,(n =7)。股骨头及髋臼关节面下囊变 (n =6)。髋臼及股骨头边缘明显硬化 ,骨赘形成 (n =6)。髋关节间隙狭窄 (n =9)。关节面及关节间隙模糊 (n =2 )。结论 :强直性脊柱炎髋关节病变出现常早于骶髂关节 ,并且是首发征象 ,它多发病于青年男性 ,CT可提供较早及确切的诊断信息。Purpose: To improve the recognization of CT diagnosis of hip joint lesions in ankylosing spondylitis. Materials and Methods: Analysis of CT manifestations in 10 cases of ankylosing spondylitis proved by clinical and CT data. Results: CT factures included:(1)narrowing of the interaticular space in hip joint(n=9).(2)ill-defined margin on the surface of articular and interarticular (n=2).(3) vermiform destruction of bone in head of femur and acctabulum (n=7).(4) Cystis under the surface of acctabulum (n=6).(5)Osteoporosis in head of femur(n=6).(6)Osteoporosis on head of femur and acctabulum(n=6). Conclusion: Hip joint lesions of ankylosing spondylitis appear earlier than sacroiliac joint and are the first signs. It is a disease mostly of young men. early age of disease onset, CT diagnosis can provide more earlier and accurate imaging informations.
