Abstract
A cervical intervertebral prosthesis system includes prostheses which each have a hinge with a predefined center of hinge movement. To permit better adaptation to the different hinge radii of the cervical intervertebral disks, the cervical intervertebral prostheses of the system include at least two prostheses with different hinge radii.
