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.
