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