Examination of the effect of lumbar disc hernia onatrophy of paravertebral muscles

Aim: In our study, we aimed to evaluate the effect of the presence of lumbar disc herniation on the atrophy of the paravertebral muscles in patients who were admitted to the hospital with the complaint of lumbalgia. Material and Methods: Following the approval of Aydın Adnan Menderes University clinical studies ethics committee, MRI images of adult patients who applied to our hospital with the complaint of lumbalgia between December 1, 2020 and June 1, 2021 began to be examined. Patients with structural deformities, lumbar region neoplasms, infectious diseases, vertebral fractures and lumbar region surgery were not included in the study. As a result of the examinations, 443 patients with low back pain and lumbar disc herniation formed the case group. The control group consisted of 135 patients with low back pain but without lumbar disc herniation. The patients were evaluated in terms of gender, age, number of lumbar disc herniations, lumbar disc herniation level, lumbar disc herniation degree, surface measurements of paravertebral muscles and atrophy of paravertebral muscles. Results And Conclusion: As a result of our study, statistical significance was found between atrophy of m.multifidus lumborum and m.quadratus lumborum muscles and LDH. In addition, the relationship of age and gender factors with LDH, lumbar disc degeneration and atrophy of paravertebral muscles were examined.
