Magnetic resonance imaging changes in multifidus and psoas muscles in patients with lumbar spinal stenosis

Objectives: The aim of this study is to evaluate the relationship between spinal canal cross-sectional area (SCCSA) at stenosis level, areas multifidus (MF) muscle L3-S1 levels, and psoas (PSCSA) L3 level in patients with nerve compression due lumbar stenosis. Methods: A total 280 were included study, 140 control group that had been detected magnetic resonance imaging (MRI). patients' ages, gender, SCCSA stenosis, PSCSA MFCSA degrees atrophy caused by fatty degeneration evaluated compared whether comparison was statistically significant or not. Results: values L3-4 (r=0.555, p < 0.01), L4-L5 (r=0.559, L5-S1 (r=0.429, 0.01) found have a positive correlation. In addition, (p 0.001), L4-5 0.001),the L3-L4 0.001) mean be significantly lower than cases group. Conclusions: Compared group, correlation decrease CSA presence However, it there no
