Abstract:

BACKGROUND: Previous studies have focused on the relationship between degenerative lumbar spondylolisthesis and low back pain and paraspinal muscle volume, and there are few studies on lumbar spinal stenosis and paraspinal muscle volume.
OBJECTIVE: To compare the differences in the cross-sectional areas of paravertebral muscles and psoas muscles between degenerative lumbar spondylolisthesis, degenerative lumbar spinal stenosis and control group.
METHODS: A retrospective analysis of the imaging data of 90 female patients undergoing abdominal or lumbar CT and MRI scans from January 2017 to August 2018 was performed. The patients were divided into group A, lumbar spinal stenosis at L4/5, group B, lumbar spondylolisthesis at L4/5 and group C (control group), no lumbar disease or symptoms. All patients signed the informed consents and the study was approved by the ethics committee of the hospital. MRI images of the axial position through the lower edge of the L3, 4, 5 vertebrae were selected to measure the muscle cross-sectional area. The vertebral body axial image was measured through the lower edge of the L3, 4, 5 bilateral pedicles to measure the cross-sectional area of the vertebral body. The Image-PRO Plus 6.0 software was used to calculate the cross-sectional area of the target muscle and vertebral body in the image, and results were compared.
RESULTS AND CONCLUSION: (1) There was no significant difference in the age distribution among groups (P=0.986). (2) There were no significant differences in the cross-sectional areas of psoas muscle and paraspinal muscle between groups A and B (P > 0.05), while the cross-sectional areas in the groups A and B were significantly less than those in the group C (P < 0.001). (3) There were no significant differences in vertebral cross-sectional areas among groups (P > 0.05). (4) In summary, in L4/5 single segment of degenerative lumbar spinal stenosis and degenerative lumbar spondylolisthesis patients, at L3, L4, L5 vertebral body lower level, the lower extremity cross-sectional areas and paraspinal muscle cross-sectional areas were decreased compared with the control group, with consistency, but the mechanisms of muscle reduction may not be exactly the same.

Key words: psoas muscle, paravertebral muscle, cross-sectional area, degenerative lumbar spondylolisthesis, degenerative lumbar spinal stenosis, lumbar CT, lumbar MRI, the National Natural Science Foundation of China
