下腰痛患者的腰椎终板退变与椎间盘退变相关性的影像学研究

Radiologic study of the correlation between Modic lumbar endplate degeneration and lumbar intervertebral disc degeneration in patients with low back pain

目的:探讨下腰痛患者腰椎终板炎(Modic退变)与椎间盘退变的相关性。方法:对90例(270个椎间盘)下腰痛患者常规行腰椎X线和MR检查。终板退变及椎间盘退变分别按Modic终板退变标准(0～3级)与Pearce椎间盘退变标准(Ⅰ～Ⅴ级)对终板和椎间盘进行评估。采用SPSS11.5统计学软件分析Modic退变与椎间盘退变的相关性。结果:90例下腰痛患者的腰椎终板Modic分级与椎间盘退变Pearce分级存在较强的相关性(PearsonR=0.452,P=0.000),Modic退变分级高,椎间盘退变分级也高。结论:腰椎终板Modic退变分级与椎间盘退变Pearce分级密切相关,提示Modic退变与椎间盘退变在腰椎退变过程中可能互为因果。两者皆为下腰痛的可能原因之一。

Objective： To discuss the correlation between Modic degeneration of lumbar endplate on MRI and degeneration of lumbar intervertebral disc in low back pain. Methods： The routine X-ray and MRI were performed in 90 patients with 270 lumbar discs. The lumbar endplate changes were divided into 0-3 grades by Modic classification and the degeneration of vertebral discs were divided into Ⅰ-Ⅴ grades by Pearce classification system. All the data were analyzed by SPSS 11.5 for the correlations. Results： There was significant correlation（Pearson R=0.452, P=-0.000）, between the Modic degeneration of lumbar endplate and the degeneration of lumbar discs in 90 patients. Conclusion： There is positive correlation between Modic degeneration of lumbar endplate and the degeneration of lumbar intervertebral disc. It suggests Modic degeneration of lumbar endplate and the degeneration of lumbar intervertebral disc might be the cause and effect of each other. Both of them might be the causes of low back pain.
