强直性脊柱炎髋关节病变的X线表现及临床分析

The analyses of hip joint lesionin ankylosing spondylities in X ray and clinic

目的探讨强直性脊柱炎(AS)髋关节病变的临床特点及其相关因素。方法对100例确诊AS患者行X线计算机摄影术(CR)骨盆正位片和人白细胞抗原B27(HLA-B27)检查。结果58%的AS患者都出现不同程度的髋关节间隙变窄、骨质增生、硬化、软骨囊性变、关节融合,幼年发病和HLA-B27阳性者发生率较高。结论AS患者的髋关节病变在CR上有一定特征性表现,与发病年龄和HLA-B27有相关性。

Objective To improve the recognization of hip joint lesion in ankylosing spondylitis and it＇s related factors. Methods Pelvis computed radiography（CR） and HLA-B27 were examined in 100 cases of ankylosing spondylitis proved by clinical. Results 58 % cases appeared differed degree of narrowing of the interticular space, osteoporosis on head of femur and acctabulum, cystis under the surface of acctabulum and joint inosculated. This probability was higher at thoe pa- tients that had diaease at youthful or HLA-B27（ ＋ ）. Conclusion Hip joint lesions of ankylosing spondylitis appear characteristic signs in CR. It relates with the age that the disease come on and HLA-B27.
