The main aim of this retrospective study was to analyze lumbopelvic sagittal parameters among the three different types of Modic changes (MCs). Furthermore, correlations between the sizes of MCs and the number of involved lumbar levels with lumbopelvic parameters are investigated.
A total of 263 adult subjects with MCs at a single institution from September 2015 to October 2020 who underwent lumbar x-ray examinations and magnetic resonance imaging were included in this retrospective study. Types of MCs, sizes of MCs, lumbar levels involved by MCs as well as lumbopelvic sagittal parameters from each subject were evaluated by two authors.
Lumbar lordosis (LL), sacral slope (SS), and pelvic incidence (PI) in subjects with MC grade 1 were significantly smaller than in those with MC grade 2 and grade 3 (p<0.05). Lumbopelvic sagittal parameters decreased significantly as the sizes aggravated (p<0.01). Triple lumbar levels with MCs showed a significant increase in PI-LL (p<0.05) and decrease in LL (p<0.01), SS (p<0.01), and PI (p<0.01) when compared to MCs at single and double lumbar levels.
MC grade 1, severe MCs, and lumbar multi-segmental MCs were significantly linked to lumbar sagittal imbalance.
本回顾性研究的主要目的是分析三种不同类型的Modic改变（MCs）中的腰骶矢状面参数。此外，还研究了MCs的大小和受累腰椎节段数与腰骶参数之间的相关性。
本回顾性研究纳入了2015年9月至2020年10月期间在单一机构接受腰椎X线检查和磁共振成像的263例患有MCs的成年受试者。两位作者对每个受试者的MCs类型、MCs大小、MCs累及的腰椎节段以及腰骶矢状面参数进行了评估。
1级MCs受试者的腰椎前凸（LL）、骶骨倾斜度（SS）和骨盆入射角（PI）显著小于2级和3级MCs受试者（p<0.05）。随着MCs大小加重，腰骶矢状面参数显著降低（p<0.01）。与单节段和双节段腰椎的MCs相比，三节段腰椎的MCs显示PI-LL显著增加（p<0.05），LL（p<0.01）、SS（p<0.01）和PI（p<0.01）显著降低。
1级MCs、严重MCs和腰椎多节段MCs与腰椎矢状面失衡显著相关。
