Abstract：
The weakening of paraspinal muscles in the paravertebral area may play a role in developing central lumbar spinal stenosis, resulting in lower back discomfort.
The study thoroughly examined the correlation between the Oswestry Disability Index, Dural Sac cross-sectional area, Schizas grading Scale, Body Mass Index, and the cross-sectional areas of Erector Spinae, Multifidus, and Psoas muscles. The findings were also compared between patients with central Lumbar Spinal Stenosis and healthy individuals.
Retrospective monocentric observational study.
The study recruited 168 consecutive patients aged 60 or older diagnosed with central Lumbar Spinal Stenosis between January 2020 and July 2022. The patients\' condition was evaluated by administering a preoperative Oswestry Disability Index questionnaire, measuring their Body Mass Index, and performing preoperative Magnetic Resonance Imaging. The analyzed parameters were the cross-sectional area of paraspinal muscles at the L4-L5 level, dural sac cross-sectional area, and Schizas grading Scale at the most stenotic level, using multiple linear univariate analyses. Two groups of healthy individuals were recruited: Group A (under 60 years old) and Group B (over 60 years old). The same data extrapolated from these groups were compared with those of patients with central lumbar stenosis using a two-tailed Mann-Whitney test.
As the Erector Spinae degenerates, the Oswestry Disability Index tends to increase. Similarly, an increase in Body Mass Index is often accompanied by a decrease in the cross-sectional area of the Erector Spinae. Low dural sac cross-sectional area is statistically linked to a reduced Multifidus cross-sectional area. Interestingly, the Schizas grading scale does not appear to correlate with changes in the cross-sectional area of the paraspinal muscles. Additionally, there is no significant difference in the cross-sectional area of the Psoas muscle between individuals with central lumbar spinal stenosis and healthy individuals.
Our study found that degeneration of the Erector Spinae plays a crucial role in the progression of perceived disability in Lumbar Spinal Stenosis. Prospective studies should investigate the long-term evolution of paraspinal muscles in decompressed patients.

摘要：
背景：椎旁区域的椎旁肌肉的减弱可能在发生中央腰椎管狭窄中起作用，导致下背部不适。
目的：该研究彻底检查了Oswestry残疾指数之间的相关性，硬脑膜囊横截面积,Schizas分级量表，身体质量指数,和直立脊柱的横截面积，Multifidus,和腰肌肌肉。还比较了中央腰椎管狭窄症患者和健康个体之间的发现。
方法：回顾性单中心观察研究。
方法：该研究招募了2020年1月至2022年7月期间诊断为中央腰椎管狭窄的168名60岁或以上的连续患者。通过执行术前Oswestry残疾指数问卷来评估患者的状况，测量他们的身体质量指数,术前进行磁共振成像。分析的参数是L4-L5水平的椎旁肌肉的横截面积，硬脑膜囊横截面积,和最狭窄水平的Schizas分级量表，使用多个线性单变量分析。招募两组健康个体:A组(60岁以下)和B组(60岁以上)。使用双尾Mann-Whitney检验将从这些组中推断的相同数据与中央腰椎管狭窄症患者的数据进行比较。
结果：当勃起脊柱退化时，Oswestry残疾指数有增加的趋势。同样，身体质量指数的增加通常伴随着直立脊柱的横截面积的减小。低硬膜囊横截面积在统计学上与减小的Multifidus横截面积相关。有趣的是,Schizas分级量表似乎与椎旁肌横截面积的变化无关。此外,在患有中央腰椎管狭窄症的个体和健康个体之间，腰大肌的横截面面积没有显着差异。
结论：我们的研究发现，脊柱直立肌的退化在腰椎管狭窄的感觉残疾的进展中起着至关重要的作用。前瞻性研究应调查减压患者的椎旁肌肉的长期演变。
