A spinal disc prosthetic for replacement of cervical and/or lumber discs, that in each case allows a limited degree of rotational articulation, as well as durability and resistance to fatigue. The prosthetic is formed with three primary layers, including a superior (upper) plate, inferior (lower) plate, and intermediate layer, in a sandwiched configuration. The superior plate member is adapted to be secured on one side to an upper vertebra in a spinal column, and has a formed concave side exposed downwardly. The inferior plate member is adapted to be secured on one side to a lower vertebra in the spinal column, and has a substantially flat side exposed upwardly. The intermediate member is sandwiched between the superior and inferior plate members with conforming sides, and a short cylindrical post protrudes downward from the intermediate member and is seated inside a circular recess in the inferior plate member to center it and to maintain a predetermined spacing there between. This allows a degree of rotational freedom. A variety of locking assemblies lock the post in the recess to prevent withdrawal, thereby increasing durability without obstructing the degree of freedom.

A spinal disc prosthetic for replacement of cervical and/or lumber discs, that in each case allows a limited degree of rotational articulation, as well as durability and resistance to fatigue. The prosthetic is formed with three primary layers, including a superior (upper) plate, inferior (lower) plate, and intermediate layer, in a sandwich. The superior plate member is adapted to be secured on one side to an upper vertebra in a spinal column, and has a formed concave side exposed downwardly. The inferior plate member is adapted to be secured on one side to a lower vertebra in the spinal column, and has a substantially flat side exposed upwardly. The intermediate member is sandwiched between the superior and inferior plate members with conforming sides, and includes a short cylindrical post protruding downward into a circular recess in the inferior plate member to center it and to maintain a predetermined spacing there between. Two lateral pins on the intermediate member fit into two corresponding slots on the inferior member as guides and allow a degree of rotational freedom, and the post includes snap-in spring fingers that lock into the recess of the inferior member to prevent withdrawal.

The present invention is a cervical plate connector system comprising cervical plates and a spacer mechanism. Ridged rails span the entire midline of the plates. Screw holes are cut into the center of one side of each of the two plates. Screws are inserted into the screw holes of each of the plates, which attach to both the superior and inferior vertebral bodies of the cervical spine. The midline of the plates have ridged rails running between screw holes. A spacer mechanism connects to the ridged rails of plates, and moves along them until the healing is complete and the two plates are adjacent to each other. A locking mechanism locks the screws into the plates of the connector system without detracting from the mobility of the spacer mechanism. The locking mechanism comprises a locking plate having screw holes, and at least one plate cover.
