Abstract
A disc prosthesis for use on a pair of adjacent vertebrae comprises upper and lower plates adapted to be mounted respectively to adjacent upper and lower vertebrae, typically using screws that extend through holes defined in the upper and lower plates and into the upper and lower vertebrae; a joint mechanism linking the upper and lower plates; and a damping system. The joint mechanism and the damping system are adapted to allow for biased relative movements between the upper and lower vertebrae.
