目的评估青少年腰椎间盘突出症(adolescent lumbar disc herniation,ALDH)患者的腰椎MRI图像上是否存在Modic改变。方法回顾分析我院2006年9月至2016年2月收治的68例ALDH患者,其中男51例,女17例;年龄11~20岁,平均(17.9±1.1)岁,术前腰椎MRI评估有无Modic改变及类型,记录椎间盘突出发生的节段、类型及椎间盘退变程度。结果本组患者共816个椎体终板(T_(12)/L_1~L_5/S_1)均未发现Modic改变存在。共408个椎间盘,其中87个(21.3%)椎间盘存在突出,其中单节段突出49例(72.1%),双节段突出19例(27.9%)。在87个突出的椎间盘中,Pfirrmann Ⅱ级27个(31.0%),Ⅲ级43个(49.4%),Ⅳ级17个(19.6%),未发现V级的椎间盘。结论 ALDH患者中未见Modic改变且椎间盘退变程度低,提示在青少年人群,椎间盘退变不是椎间盘突出症发病的主要病因。
Objective To assess the presence of Modic changes in lumbar MRI images of adolescent lumbar disc herniation (ALDH) patients. Methods A retrospective analysis of 68 patients with ALDH admitted from September 2006 to February 2016 in our hospital, including 51 males and 17 females, aged from 11 to 20 years (mean, 17.9 ± 1.1 years). Preoperative MRI evaluation of lumbar spine No Modic changes and types, record the occurrence of disc herniation of the segments, types and degree of disc degeneration. Results There were 816 vertebral endplates (T_ (12) / L_1 ~ L_5 / S_1) in this group without Modic changes. There were 408 intervertebral discs, of which 87 (21.3%) had disc herniations. Among them, 49 cases (72.1%) showed single segment prominence and 19 cases (27.9%) showed double segmental prominence. Of the 87 prominent discs, 27 (31.0%) were grade Pfirrmann, 43 (49.4%) were grade III, 17 (19.6%) were grade IV, and no grade V discs were found. Conclusion No changes of Modic and low degree of disc degeneration are found in patients with ALDH, which suggests that disc degeneration is not the main cause of disc herniation in adolescent population.
