    摘要： Instruments and methods are provided for implanting nucleus replacement material in an intervertebral disc nucleus space employing an inserter having proximal and distal end regions and a passageway effective for passing the material therethrough. The distal end region of the inserter includes a conical-shaped outer surface, and the passageway exits through a side surface of the inserter in the distal end region at other than the apex of the conical-shaped outer surface. The nucleus replacement material passing through the inserter exits into an intervertebral disc nucleus space when the passageway exit in the side surface at the distal end region is disposed in the nucleus space. The instrument may also include a cover locking mechanism having pivotally connected first and second cover plates with a latching tab and landing sized and configured to mate and lock the cover plates automatically when the inserter assumes an implanting configuration.

    摘要： Spinal prosthetic devices having various engagement structures are disclosed. In one aspect a spinal prosthesis system comprises a first component with a first engagement structure extending from a surface of the first component at an oblique angle and a second component with a second engagement structure extending from a surface of the component at an oblique angle. In another aspect, a pair of flange members extend from the first engagement surface at an oblique angle such that the flange members are substantially perpendicular to one another. In another aspect, a first flange member extends transversely from the first engagement surface at a first oblique angle to the longitudinal axis of the surface and a second flange member extends transversely from the first engagement surface at a second oblique angle to the longitudinal axis such that the flange members are non-parallel.

    摘要： Spinal prosthetic devices having selectable and/or changeable centers of rotation are disclosed. In one aspect, a spinal prosthesis kit includes a first component, a second component, and a plurality of inserts. The first component has a first articulating surface that includes a first articulating structure. The second component has a second articulating surface with a recessed opening adapted to receive one of the plurality of inserts. Each of the plurality of inserts includes a second articulating structure adapted to moveably mate with the first articulating structure. The second articulating structure is positioned in a different location on each of the plurality of inserts. In some embodiments, the articulating structures are moveably mating projections and recesses. In another aspect, a revisable prosthetic device having a first component, a second component, and an insert is provided.
