Objective:
To investigate the effect of cervical spine instability on sympathetic cervical spondylosis.
Methods:
Twelve patients with cervical spondylosis showing sympathetic symptoms from 1992 to 2 000 were evaluated for cervical spine instability, immobilization of collar brace, MRI and surgical results.
Results:
Radiologic evaluation cervical instability was observed radiologically in 7 of the 12 cases. Collar brace was obviously effective in 5 of the 12 cases and slightly effective in 7 cases. MRI showed abnormal signal for instability of the cervical spine in 7 cases. Surgery was markedly effective in 7 cases and moderately effective in 4 cases.
Conclusion:
Cervical spine instability was an important factor for sympathetic cervical spondylosis, which can be improved effectively by surgery.
