Abstract:
1. A spinal implant assembly for placement in a motion segment comprising two adjacent vertebrae and across an intervertebral space between the two adjacent vertebrae; the spinal implant assembly comprising: first means for anchoring the spinal implant assembly to the more cephalad of the two adjacent vertebrae; second means for anchoring the spinal implant assembly to the more caudal of the two adjacent vertebrae, a prosthetic nucleus material placed to at least partially fill the intervertebral space; a pivot so that after the spinal implant assembly is anchored to both of the two adjacent vertebrae, the vertebrae can move relative to each other; at least one elastomeric component to allow motion of the spinal implant assembly in response to compressive loading and; a threaded component that can be selectively moved along a long axis of the spinal implant assembly to controllably distribute load between the prosthetic nucleus material and the anchored spinal implant assembly to the two adjacent vertebrae.
