Abstract:
1. A spinal joint kit for replacement of a portion of a mammalian spine comprising a spinal motion segment comprising an intervertebral disc between two consecutive vertebrae, the kit comprising: an artificial disc adapted to be incorporated into the spinal motion segment, the artificial disc comprising opposing end plates, wherein the end plates are movable relative to each other; and a prosthesis, wherein the prosthesis is discrete from the artificial disc and is adapted to be incorporated into the spinal motion segment, the prosthesis comprising an articular surface that replicates a natural articular surface of a vertebral facet; wherein, when the artificial disc and the prosthesis are operatively connected to the spinal motion segment, the artificial disc restores articulation between vertebral bodies of the vertebrae, the prosthesis articulates with another facet, no portion of the prosthesis contacts a posterior arch of the vertebrae, and the artificial disc and the prosthesis cooperate to restore natural biomechanics of the spinal motion segment.
