Abstract
An anterior cervical compression plate has a pair of slidable inserts, one situated in a recess at either end of the plate. The inserts, and the sides of the recesses, having meshing raked teeth which permit the inserts to move only toward one another. The inserts have openings which are placed over the heads of screws installed in the vertebrae, and maintain compression of bone grafts between the vertebrae. A special tool is also provided to aid the surgeon in installing in the vertebrae central screws which are engaged by the inserts.
