Abstract
The present invention provides artificial disc prostheses, methods and instrumentation for implantation and revision thereof. Each prosthesis may comprise superior and inferior end plates and a nucleus positioned between articular surfaces of the end plates. The end plates may have planar bone engagement surfaces with a plurality of self-cutting teeth. The articular surfaces of the end plates may be planar or include a flattened portion. The nucleus includes superior and inferior articular surfaces which may comprise flattened portions such that when the articular surfaces of the nucleus and the end plates are placed in cooperation in a preferred orientation, the flattened and/or planar portions are aligned. Each prosthesis may provide flexion/extension, anterior/posterior translation, lateral bending, and/or axial rotation degrees of freedom. One embodiment comprises a prosthesis with a first joint providing flexion/extension and anterior/posterior translation, and a second joint providing lateral bending and axial rotation.
