Degenerative lumbar spinal stenosis (DLSS) is a condition in which the body is held in a poor posture for a long period of time, resulting in a change in the stress structure of the lumbar spine that causes degenerative changes in the muscles of the spine. The sagittal balance of the spine and pelvis and the degeneration of the paravertebral muscles have been the focus of recent research. To explore the relationship between paraspinal muscle degeneration and changes in spine-pelvic sagittal parameters in patients with DLSS, 95 patients with DLSS (experimental group) and 70 healthy volunteers (control group) hospitalized in the Ordos Central Hospital between January 2020 and January 2022 were included as study subjects. All patients underwent lumbar magnetic resonance imaging and spinal X-ray using uniform criteria. The correlation between paravertebral muscle parameters and sagittal-pelvic sagittal parameters in patients with DLSS was obtained from two imaging examinations, and the data were organized and grouped in order to explore the correlation between these parameters. There was no significant difference in the general data between the two groups (P>0.05). In the L4-5 DLSS patient group, the ratio of fat infiltration in the right erector spinae (ES) muscle was negatively correlated with thoracic kyphosis (TK) (r=-0.536; P<0.05) but not significantly in the left side. The relative cross-sectional area of the left multifidus muscle (MF RCSA) was positively correlated with TK (r=0.685; r=0.615; P<0.05) but not significantly in the right side. In the L5-S1DLSS patient group, the right MF RCSA and right ES RCSA were significantly positively correlated with TK (r=0.685; r=0.615; P<0.05) but not significant in the left side. Thus, paravertebral muscle parameters were correlated with spinal-pelvic sagittal parameters in patients with DLSS.
退行性腰椎管狭窄症（DLSS）是一种身体长期保持不良姿势的病症，导致腰椎应力结构发生变化，进而引起脊柱肌肉的退行性改变。脊柱和骨盆的矢状面平衡以及椎旁肌的退变一直是近期研究的重点。为了探讨DLSS患者椎旁肌退变与脊柱 - 骨盆矢状面参数变化之间的关系，选取2020年1月至2022年1月在鄂尔多斯市中心医院住院的95例DLSS患者（实验组）和70例健康志愿者（对照组）作为研究对象。所有患者均按照统一标准进行腰椎磁共振成像和脊柱X线检查。通过两项影像学检查获得DLSS患者椎旁肌参数与矢状 - 骨盆矢状面参数之间的相关性，并对数据进行整理和分组，以探讨这些参数之间的相关性。两组患者的一般资料差异无统计学意义（P>0.05）。在L4 - 5 DLSS患者组中，右侧竖脊肌（ES）脂肪浸润率与胸椎后凸（TK）呈负相关（r = -0.536；P<0.05），而左侧无明显相关性。左侧多裂肌相对横截面积（MF RCSA）与TK呈正相关（r = 0.685；r = 0.615；P<0.05），右侧无明显相关性。在L5 - S1 DLSS患者组中，右侧MF RCSA和右侧ES RCSA与TK呈显著正相关（r = 0.685；r = 0.615；P<0.05），左侧无明显相关性。因此，DLSS患者的椎旁肌参数与脊柱 - 骨盆矢状面参数相关。
