目的总结强直性脊柱炎的X线影像特征,提高X线诊断准确率。方法回顾性分析60例经临床确诊强直性脊柱炎患者的X线影像学资料。结果患者均有不同程度骶髂关节骨质破坏,56例为双侧对称性侵犯,4例为单侧侵犯;47例有脊柱改变,均累及腰椎,其中24例向上累及胸椎,8例累及颈椎;有髋关节异常23例,膝关节异常7例,踝关节异常4例及肩关节异常5例;跟骨结节肌腱附着处骨膜增生呈“羽毛状”改变2例;坐骨结节、股骨大转子骨质浓密硬化9例。结论 X线影像表现为骶髂关节骨质破坏是确诊强直性脊柱炎的重要依据。
Objective To summarize the X-ray features of ankylosing spondylitis and improve the diagnostic accuracy of X-ray. Methods A retrospective analysis of 60 cases of clinically diagnosed ankylosing spondylitis in patients with X-ray imaging data. Results All patients had different degree of osseous destruction of sacroiliac joint, 56 cases had bilateral symmetry violation, 4 cases had unilateral invasion, 47 cases had spine changes involving the lumbar spine. Among them, 24 cases had thoracic vertebrae upward and 8 cases had cervical spine ; There were 23 cases of abnormal hip joint, 7 cases of abnormal knee joint, 4 cases of ankle joint abnormalities and 5 cases of abnormal shoulder joint. The periosteal hyperplasia of calcaneal nodules showed “feathery” changes in 2 cases. The ischial tuberosity, Large femoral trochanteric sclerosis in 9 cases.
