Abstract
We have observed dynamic studies of the cervical spine by means of cineradiography in patients with cervical osteochondrosis. In this report slipping of the cervical vertebral body in flexion-extension of the cervical spine is the main topic.
Slipping of the body was seen in almost every cases of normal person, but the de gree was slight.
On the other hand, in patients with cervical osteochondrosis there were some cases which showed definite slipping of the body mainly at the level adjacent above to the level of the lesion.
After interbody fusion of the lesion, the slipping of the body increased slightly compared to that of preoperation, especially at the level adjacent above the level of the fusion.
