Abstract

Objective:To investigate the correlation and clinical significance between the morphological changes of paraspinal muscles and the grade of lumbar disc degeneration in patients with lumbar disc herniation. Methods: The clinical data of 100 patients with lumbar disc herniation who were treated in Xi'an Traditional Chinese Medicine Hospital from January 2018 to January 2021 were collected. And according to the patient's lumbar spine magnetic resonance imaging (MRI), the multifidus, erector spinae, and psoas major cross-sectional area (CSA) of the patient's lumbar L3-S1 intervertebral disc level were measured, and the morphological changes of the paraspinal muscles were summarized., and graded the degree of lumbar intervertebral disc degeneration according to Pfirrmann criteria (grade I-V). Pearson correlation analysis method was used to evaluate the correlation between paraspinal muscle morphology and lumbar disc degeneration grade. Results: The higher the degeneration grade of the L2-L3 intervertebral disc, the smaller the CSA of the psoas major. The higher the degeneration grade of the L3-L4 lumbar disc, the smaller the psoas CSA. The higher the grade of L4-L5 disc degeneration, the smaller the psoas major CSA. Conclusion: The area of the psoas major in patients with lumbar disc herniation is closely related to the grade of intervertebral disc degeneration, and the health of the paraspinal muscles is related to the lower back pain in patients with lumbar disc herniation. Clinically, the health of the paraspinal muscles can be evaluated according to the grade of degeneration. The severity of the disease can guide treatment and can make rehabilitation recommendations for the patient's prognosis.
