分析腰椎小关节病的CT常见表现

目的回顾性分析腰小关节病的CT表现。方法选择68例腰椎小关节病患者，分析CT影像改变并记录临床表现。结果68例患者表现为不同节段的腰椎小关节改变，CT表现为骨赘形成，关节突增生肥大，关节面软骨破坏，关节间隙变窄，关节真空现象，关节囊的钙化和囊肿等。结论腰椎小关节病是引起腰痛及腰腿痛的重要病因之一，常合并腰椎间盘退变。由于以往检查技术的局限以及过分强调了椎间盘的作用，造成对此病的认识不足，小关节病CT表现特异性强，对此病的诊断和治疗均有重要指导意义。

Analysis of CT for Common Appearance of Lumbar Facet diseases

Objective Objective To analysis the diagnostic appearance of CT scan in the evaluation of degenerative lumbosacral disease with facet joint participation.Methods A Series of 68 cases of lumbar facet diseases were examined with CT scan to analyze changes of CT and to record clinical situation.Results Abnormal facet joints were found in 68.Abnormalities demonstrated by CT included osteophyte formation,hypertrophy of articular processes,focal cartilage necrosis,articular cartilage thinning,vacuum joint phenomenon,calcification of the joint capsule and synovial cyst.Conclusion Lumbar facet disease is one of the important causes of low back pain and sciatica,and usually in company with lumbar disc herniation.It has been ignored because of the limitation of examination technique used before and overemphasis of disc herniation.Diagnostic value of CT in the study of lumbar facet joint disease offers a reliable evaluation with high sensitivity and specificity,in order to make appropriate therapeutic decisions.
