目的:探究终板骨折引起椎间盘退变和Modic改变的影像学随访价值。方法:选择浙江省长兴县人民医院2016年1—12月收治的终板骨折患者46例作为研究对象，并进行1年随访。患者均采用MRI检查，分析比较随访前后患者的Modic改变、椎间盘退变及腰椎功能恢复情况。结果:入选46例患者共230个腰椎椎间盘，均发生Modic改变；随访1年后，46例患者共185个腰椎椎间盘发生Modic改变，Modic改变多发于Ln 5 ~ Sn 1[38.92%（72/185）]、Ln 4 ~ Ln 5[40.0%（74/185）]节段。随访1年后，46例患者的椎间盘分级3 ~ 4级率高于出院前[70.43%（162/230）比60.43%（139/230）]，6 ~ 8级率低于出院前[8.70%（20/230）比15.22%（35/230）]，差异均有统计学意义（n χn 2=5.085、4.646，n P0.05）。随访1年时患者的腰椎功能评分为（23.47 ± 2.86）分，高于出院前的（9.15 ± 1.32）分，差异有统计学意义（n t=30.834，n P<0.05）。n 结论:磁共振扩散加权成像具有操作便捷、重复性好、准确率高的特点，适用于终板骨折引起椎间盘退变和Modic改变诊断和追踪随访，值得临床推广。“,”Objective:To investigate the imaging follow-up value of discectomy and Modic changes caused by endolate fracture.Methods:Forty-six patients with end-plate fractures admitted to Changxing People′s Hospital during January to December 2016 were selected as subjects and followed up for 1 year. All patients underwent MRI examination to analyze the changes of Modic, disc degeneration and lumbar function recovery before and after follow-up.Results:A total of 230 lumbar intervertebral discs in 46 patients in this group had Modic changes. After 1 year′s follow-up, Modic changes occurred in 185 lumbar intervertebral discs in 46 patients. Modic changes occurred in Ln 5-Sn 1 [38.92%(72/185)] and Ln 4 - Ln 5 [40.0%(74/185)] segments. After 1 year′s follow-up, the rate of intervertebral disc 3-4 grade was higher than that before discharge [70.43%(162/230) vs. 60.43%(139/230)], the rate of intervertebral disc 6-8 grade was lower than that before discharge[8.70%(20/230) vs. 15.22%(35/230)], and the differences were statistically significant (n χ2 = 5.085, 4.646, n P<0.05). After 1 year′s follow-up, the lumbar spine function score was significantly higher than that before discharge [(23.47 ± 2.86) scores vs. (9.15 ± 1.32) scores], and the difference was statistically significant (n P<0.05).n Conclusions:Diffusion-weighted MR imaging has the characteristics of convenient operation, good repeatability and high accuracy. It is suitable for diagnosis and follow-up of disc degeneration and Modic change caused by endplate fracture. It is worthy of clinical promotion.
