OBJECTIVES
To analyze whether multifidus degeneration has a relationship with degenerative lumbar spinal stenosis (LSS).
MATERIALS AND METHODS
Clinical data of 40 patients with LSS were analyzed retrospectively. Moreover, 40 healthy people were selected as controls. Subjects of both groups underwent a 1.5-T lumbar spinal magnetic resonance imaging scan in our hospital, and then the multifidus muscularity, fatty infiltration ratio, and bilateral asymmetry at L4/5 level on magnetic resonance imaging were measured with ImageJ software to analyze and compare the multifidus parameters between the 2 groups.
RESULTS
Compared with the control group, the multifidus muscularity was lower, fatty infiltration ratio was greater, and muscle asymmetry was more significant at the L4/5 level in patients with LSS, and the difference between the 2 groups was statistically significant.
CONCLUSIONS
Multifidus degeneration, including reduced volume, increased fatty infiltration, and bilateral muscle asymmetry, has an association with LSS.
目的
分析多裂肌退变与退变性腰椎管狭窄症（LSS）是否存在关联。
材料与方法
回顾性分析40例LSS患者的临床资料。此外，选取40名健康人作为对照。两组受试者均在我院接受1.5-T腰椎磁共振成像扫描，然后使用ImageJ软件测量磁共振成像上L4/5水平的多裂肌肌肉量、脂肪浸润率和双侧不对称性，以分析和比较两组之间的多裂肌参数。
结果
与对照组相比，LSS患者在L4/5水平的多裂肌肌肉量更低，脂肪浸润率更高，肌肉不对称性更显著，两组之间的差异具有统计学意义。
结论
多裂肌退变，包括体积减小、脂肪浸润增加和双侧肌肉不对称，与LSS有关联。
