目的：腰椎 Modic 变化（MC）的运动学特征鲜有报道；此外，在分析MC的运动特性时，没有考虑椎间盘退变（DD）对节段运动的影响。因此，本研究旨在根据不同DD等级评估MC的运动学特征。方法：回顾性分析894例患者4470个腰椎节段，选择有MC的患者进行节段运动评估。 MC类型定义为0、I、II、III级，DD分级分为A级至E级5组。根据屈伸位置的X线图像计算节段角运动和平移运动，并记录差值的绝对值。结果：在260例患者的308个节段中观察到MC。 DD A级未发现MC，DD B级未观察到MC III。发现MC I在DD E级组中显着增加角运动，MC II可以在DD级D组中放大平移运动（均P < 0.05）； MC III 在角运动和平移运动方面具有最低的节段运动；所有DD级别组中MC I和MC II之间的角运动和平移运动均无统计学差异（均P>0.05）。结论：MC III表示节段运动的最终稳定阶段。 MC I 可能会增加角运动，MC II 会增加被认为稳定的部分中的某些平移运动。
OBJECTIVE: The kinematic characteristics of Modic changes (MCs) in the lumbar spine have rarely been reported; furthermore, the effect of disc degeneration (DD) on segmental motion has not been considered in analyzing the motion characteristics of MCs. Therefore, this study was designed to evaluate the kinematic characteristics of MCs based on different DD grades.METHODS: 894 patients with 4470 lumbar segments were reviewed, and those with MCs were selected for segmental motion evaluation. MC type was defined as 0, I, II, and III, and DD grade was classified into 5 groups from grade A to grade E. Segmental angular and translational motion were calculated from X-ray images in positions of flexion and extension, and the absolute values of the differences were recorded.RESULTS: MCs were observed in 308 segments from 260 patients. No MC was found in DD grade A, and MC III was not observed in DD grade B. MC I was found to significantly increase angular motion in the DD grade E group, and MC II could enlarge translational motion in the DD grade D group (all P < 0.05); MC III had the lowest segmental motion in both angular and translational motion; There was no statistical difference in angular and translational motion between MC I and II in all DD grade groups (all P > 0.05).CONCLUSIONS: MC III indicates the final stable phase of segmental motion. MC I might increase angular motion, and MC II would increase certain translational motions in the segments that were believed to be stable.
