4. A method of assembling a cervical plate system, comprising the steps of:
-
providing a cervical plate having a thickness between a top surface and an opposite bottom surface, and a first slot extending through the thickness of the plate; providing a first rotating element comprising a top surface, an opposite bottom surface, and at least one threaded hole extending from the top to the bottom surface of the rotating element; orienting the first rotating element so that its top and bottom surfaces are generally perpendicular to the top and bottom surfaces of the cervical plate; and pressing the first rotating element into the first slot.

5. A method of implanting a cervical plate system onto the vertebrae of a patient, comprising the steps of:
-
selecting a cervical plate system for the patient, the system comprising; a cervical plate having a thickness between a top surface and an opposite bottom surface, and at least one slot extending through the thickness of the plate and corresponding to the vertebra to which it will be attached; and at least one rotating element positioned within at least one slot of the cervical plate, the at least one rotating element comprising at least one threaded hole; positioning the cervical plate on top of the vertebrae of the patient; attaching a drill sleeve to each of the at least one threaded holes of the at least one rotating element; rotating the at least one rotating element within the at least one slot until the at least one rotating element is in a desired position relative to the vertebra; inserting a drill into each drill sleeve and drilling a screw hole into the vertebrae; inserting a bone tap through the at least one threaded hole of the rotating element and into the screw hole in the vertebrae; tapping a hole in the vertebrae that has threads that match threads of the threaded hole of the at least one rotating element; and inserting a bone screw into the threaded hole of the at least one rotating element and into the corresponding hole in the vertebra.
