目的：探讨腰椎后部结构MRI退变征象与慢性下腰痛的关系。方法：对在北京大学第三医院行腰椎MRI检查的患者进行问卷调查，选取问卷有效的慢性下腰痛者139例为研究对象，其中68例有神经根压迫为A组，71例无神经根压迫为B组。另选取无下腰痛、无神经根压迫症状的62例职工作为对照组（C组）。观察以下MRI征象：平均小关节退变分级（average facet joint degeneration scores，AZZ）、小关节积液、棘间韧带高信号、皮下或椎后旁肌肉水肿。对MRI征象在不同组的分布特征行统计学分析。结果：3组AZZ的中位数分别为0.67、0.67、0.08，小关节积液发生率分别为32.4%、26.8%、14.5%，棘间韧带高信号发生率分别为42.6%、47.9%、58.1%，皮下或椎后旁肌肉水肿发生率分别为20.6%、22.5%、4.8%。其中，A、B组的AZZ、皮下或椎后旁肌肉水肿发生率比较差异均无统计学意义（均P>0.05），但均比C组高（均P<0.05）。小关节积液发生率、棘间韧带高信号发生率在3组间差异均无统计学意义（均P>0.05）。结论：AZZ、皮下或椎后旁肌肉水肿可能与慢性下腰痛有关。

Objective:To investigate the relationship between the MRI findings of posterior lumbar elements and chronic low back pain (CLBP). Methods:The patients underwent lumbar MRI examinations were sent questionnaires about low back pain (LBP). Among them,139 patients whose questionnaires were useful with CLBP were enrolled and divided into two groups:group A included 68 patients with nerve roots compression,and group B included 71 patients without nerve roots compression. 62 hospital staffs without LBP and nerve roots compression were recruited as control group C. The MRI findings included average facet joints degeneration scores (AZZ),facet joint effusion,high T2 signal in interspinous ligament and subcutaneous/paraspinal muscles edema. The distribution difference of MR findings in three groups above was analyzed. Results:To group A,B and C, the AZZ median was 0.67,0.67 and 0.08,respectively,the incidence rate of facet joint effusion was 32.4%,26.8% and 14.5%, respectively,the incidence rate of high T2 signal in inerspinous ligament was 42.6%,47.9% and 58.1%,respectively,and the inci-dence rate of subcutaneous/paraspinal muscles edema was 20.6%,22.5% and 4.8%,respectively. AZZ and the incidence of subcu-taneous/paraspinal muscles edema between group A and B were similar (P>0.05),but were significantly higher than group C (P<0.05). The incidence of facet joint effusion,the incidence of high T2 signal in interspinous ligament had no statistically difference within three groups (P>0.05). Conclusion:AZZ,subcutaneous/paraspinal muscles edema are probably associated with CLBP degree.
