Abstract:

BACKGROUND: Lumbar spinal stenosis is a common disease in the clinic, and the imaging manifestations and etiology are complex. There are few studies on the degeneration of lumbar facet joints, which needs further investigation.
OBJECTIVE: To investigate the relationship between lumbar facet joint arthritis and lumbar facet joint angle in cross-sectional observation of MRI in patients with lumbar spinal stenosis.
METHODS: In T2WI of MRI, L4/5 and L5/S1 segment bilateral lumbar facet joint angle of 120 patients with lumbar spinal stenosis was assessed and we measured the lumbar facet joint angle grade on both sides. Then, the changes of bilateral lumbar facet joint angle of different segments and lumbar facet joint angle MRI were observed. Finally, the relationship among them was analyzed. Informed consents were obtained from all patients, and the study was approved by the Ethics Committee of the hospital.
RESULTS AND CONCLUSION: (1) There were significant differences between L4/5 and L5/S1 in the angle of lumbar facet on the left and right sides of the same segment (P < 0.05). (2) There was no significant difference in the number of bilateral cases between lumbar facet joint angle groups with different grades of the same segment (P > 0.05), while there were significant differences in the angle of bilateral lumbar facet joints (P < 0.05). (3) For lumbar facet angle, it showed no correlation with age, gender and body mass index in the two segments (P > 0.05), while lumbar facet joint angle grade on the left showed little correlation with gender and body mass index (P < 0.05), and there was a negative correlation between lumbar facet angle and lumbar facet joint angle grade (P < 0.05). (4) In summary, there is a negative correlation between lumbar facet angle and lumbar facet joint angle in patients with lumbar spinal stenosis. The more severe lumbar facet joint angle is, the more sagittal the lumbar facet joint is. The pathological changes of them are important imaging features of spinal stenosis, providing evidence for clinicians to understand the influence of paravertebral structural degeneration correctly and deeply.

Key words: lumbar spinal stenosis syndrome, lumbar facet joint, osteoarthritis of lumbar facet joint, osteoarthritis grade, MRI, sagittal
