目的:探讨早期强直性脊柱炎骶髂关节病变的X线表现并进行比较分析,提高对其X线表现的认识。方法:对62例临床确诊为强直性脊柱炎的X线表现进行分析,总结其X线表现。结果:24例骶髂关节面模糊及轻度硬化,关节间隙正常且受累部位在骶髂关节中下部的病例,32例骶髂关节中下部关节面骨质明显的局限或广泛骨质小囊状破坏,间隙狭窄,骨质破坏,部分增生硬化的病例,6例骶髂关节关节面融合,骨性强直。结论:骶髂关节面模糊,关节面下骨质局限性硬化及小囊状改变为其早期影像特征,对临床早期诊断具有重要价值。
Objective: To investigate the X-ray manifestations of sacroiliac joint lesions in patients with ankylosing spondylitis and to compare and analyze them to improve their X-ray findings. Methods: X-ray findings of 62 cases of clinically diagnosed ankylosing spondylitis were analyzed and X-ray findings were summarized. Results: Twenty-four patients with sacroiliac joint surface were fuzzy and mildly sclerosis, the joint space was normal and the affected site was in the lower part of the sacroiliac joint. The osteoarthritis of the middle and lower part of the sacroiliac joint was obviously limited or extensive Vandalism, narrowing of space, bone destruction, partial hyperplastic sclerosis cases, 6 cases of sacroiliac joint articular surface fusion, ankylosis. Conclusion: The sacroiliac articular surface is blurred, the sclerosis of the bones in the articular surface and the small cystic changes are its early imaging features, which is of great value in early clinical diagnosis.
