Objective: To investigate the relationship between the plain x-ray findings and MR imaging of the cervical spine in the herniated disc and degenerative spondylosis to identify the questionable points of disc space narrowing, neural foramen narrowing, disc degeneration, spinal column straightening, segmental instability and physical examination.
Method: Fifty-six herniated disc subjects were compared with 24 control subjects to analyze several radiologic indicators such as the height of disc space, height and width of neural foramen, Kellgren grade of vertebral body, Cote grade of facet joint, angle of cervical lordosis, and horizontal displacement of flexion-extension instability.
Results: Disc space was narrowed in the herniated disc group but there was no statistically significant difference compared to the control group. Neural foraminal diameters were significantly decreased in height at C6-7, and width at C5-6 in the herniated disc group. Degeneration grade of Kellgren and Cote were higher in the herniated group than control group. Lordotic angle, segmental instability were not different between two groups. Spurling sign was more frequently positive in herniated group.
Conclusion: Neural foramen diameter changes, degree of degeneration, and the presence of the Spurling sign were found to be significant findings associated with a herniated cervical disc, whereas no definite association was observed with disc space narrowing.
