摘　　要：目的　评价CT对腰椎小关节综合征的诊断价值。方法　回顾分析 64例小关节综合征的CT表现。男 5 3例 ,女 11例。年龄 3 9～ 70岁 ,平均 5 4.5岁。结果　腰椎小关节异常的主要CT表现为 :(1)小关节突增生、肥大及骨赘形成 ,并导致关节间隙、侧隐窝、椎间孔及椎管狭窄。 (2 )关节面硬化 ,硬化骨质内囊样低密度区及关节面边缘缺损。 (3 )关节腔内“真空”现象 ,小关节不对称及关节半脱位。结论　CT可充分地显示椎小关节的解剖结构和病理改变 。Objective To evaluate CT diagnostic value in the facet syndrome of lumbar spine.Methods CT fingings in 64 cases with facet syndrom were retrospectively analysed,53 males and 11 females,aged 39～70 years with a mean of 54.5.Results The main abnormalties demonstrated by CT included:(1)Hypertrophy of articular process,osteophyte formation,leading to stenosis in joint,lateral recess,lumbar intervertebral foramen and lumbar spinal canal.(2)Sclerosis of articular aspect,cystic region and defect on boder of the articular aspect.(3)Vacuum phennomenon,asymmetry of the joint and subluxations.Conclusion CT can demonstrate anatomic structure and pathologic change of the articular joints clearly,and provide reliable images for diagnosis of facet sydrome.
