An artificial disc implant is described that comprises of two plates that
have articulating surfaces interfacing with each other. In between the
plates and surrounding the articulating surface is a flexible and elastic
insert puck. The insert puck will have a hole that allows the two
articulating surfaces to interact with one another. The articulating
surfaces will also be shaped to allow different ranges of angular
movements between the two endplates depending on the direction of the
motion. The insert puck will provide protection to the articulating
surfaces at the point of interaction and will provide cushion to the
plates as they move relative to one another.
