ABSTRACT:
An articulating joint implant for use in the cervical spine includes a pair of opposing upper and lower elements having nested articulation surfaces providing a center of rotation of the implant above the adjacent vertebral body endplate surfaces in one mode of motion lateral bending and a center of rotation of the implant below those surfaces in flexion/extension, and that further permit axial rotation of the opposing elements relative to one another about the longitudinal axis of the spinal column through a range of angles without causing them to move in opposing directions along the longitudinal axis within that range. In preferred embodiments, the articulation surfaces further cause such opposite movement of the opposing elements beyond that range.
