Abstract
An apparatus and method is provided relating to artificial discs. An artificial disc is provided that facilitates simultaneous and independent articulation of flexion/extension, lateral bending, anterior/posterior translation, and axial rotation. The artificial disc provides these four simultaneous and independent articulations by independently addressing each type of articulation in the design of the artificial disc. In one example, an artificial disc is comprised of a bearing disposed between first and second end plates. The bearing is movable relative to each end plate, independent of the other end plate. The end plates are affixed to adjacent vertebrae.
