Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a cross bar mounting element having a socket into which the head of the screw is initially polyaxially nested. The cross bar mounting element further includes a vertical split which permits the socket to be expanded or compressed via the application of a corresponding force directed at the split. The cross bar mounting element further includes a pair of upwardly extending members which define a trough into which a cross bar element is positioned. The cross bar element includes features which permit the secure fixation of a rod thereto, as well as a selectively slideable element, such as a nut, which may be tightened to apply the compressive force necessary to compress the interior volume onto the head of the screw, thus locking the assembly in place.

Abstract: A hook device for use with support rod implantation apparatus is disclosed which is positionable along the central axis of the posterior surface of the spine and has independently rotationally positionable blade and head portions. The head portion is engageable with a deflecting top cylindrical portion which sits above the lamina. The insertion, and subsequent locking of a rod in the rod receiving channel of the head portion causes the blade portion and the head portions to be compression locked together by virtue of an interference fit.

Abstract: An intervertebral implant includes a first plate having an inner surface, an outer surface, a ball shaped protuberance projecting from the inner surface and an annular groove surrounding the ball shaped protuberance. The implant includes a second plate having an inner surface, an outer surface, a curvate socket formed in the inner surface of the second plate and a raised rim surrounding the curvate socket. The first and second plates are assembled together so that the inner surfaces of the plates oppose one another and the ball shaped protuberance is disposed in the curvate socket and the annular groove aligned with the raised rim. The assembled first and second plates angulate and rotate relative to one another.

Abstract: An artificial intervertebral disc having a pair of opposing plate members for seating against opposing vertebral bone surfaces, separated by a ball joint coupling. One plate member has a centrally located ball-shaped protrusion that is rotatably coupled in a central socket in a cone-shaped protrusion on the other plate member. Thereby, the plate members are angulatable with respect to one another. Further, the disc assembly will not come apart under tension loads applied to the plate members, and the location of the ball joint coupling provides the disc assembly with a stationary centroid of motion that is centrally located between the vertebral bone surfaces, both causing the disc assembly to behave similarly in these respects to a healthy natural intervertebral disc.

Abstract: An instrument for inserting an implant between vertebral bodies, including a holder adapted to hold the implant during insertion of the implant between the vertebral bodies, a retractor adapted to retract the holder away from the implant after the insertion, and a guard adapted to prevent the implant from being removed from between the vertebral bodies during the retraction.
