腰椎小关节综合征CT诊断与临床意义

Lumbar facet syndrome: CT findings and clinical significance

目的 :分析腰椎关节突间小关节综合征的CT征象及其临床意义。方法 :76例患者均行CT轴位平扫 ,扫描包括L1 2 至L5 S1椎间盘。扫描层面平行于椎间隙平面 ,扫描距阵 5 12× 5 12。计算数据的百分比。结果 :腰关节突间小关节发病率随着年龄的增长也逐渐增加 ,以 5 0～ 6 0岁之间最多 ;发病部位以L4 5椎间关节最常见 ;CT主要表现为 :小关节面硬化 ;小关节突增生肥大及骨赘形成 ;小关节腔真空征 ;小关节面不对称 ;关节囊及关节周围钙化 ;皮质下骨囊性病变 ;小关节半脱位。结论 :结合临床表现 ,CT扫描可准确诊断腰椎关节突间小关节综合征。

Objective: To evaluate the CT findings of the lumbar facet syndrome and their clinical significance. Methods: Seventy six patients underwent axial plain scans from discs of L 1 2 to L 5 S 1. CT scans were performed on a scanner with a 512×512 matrix. The percentage of the data was calculated. Results: The incidence of the lumbar facet syndrome increased with the advancing age of patients. Most of the patients suffering from the disease were 50 to 60 years old. The involved parts mostly located between the L 4 and L 5 intervertebral joint. The CT findings were as follows: sclerosis asymmetry of articular surface, hyperplasia of articular process, proliferation of osteophyte, vaccum of articular cavity, calcification of articular capsule and periarthrosis, cystic degeneration of subcortex of bone, and semiluxation of joint, etc. Conclusion: CT scan can accurately diagnose the lumbar facet syndrome in the clinical practice.
