Anatomically contoured anterior cervical plates with bone ingrowth
surfaces, providing for intersegmental compressive preloading, and a
rigid and locked interface to all of the bone screws, with those engaging
the vertebrae deployed in highly convergent pairs. The bone screws have a
tapered self-tapping leading end, an increasing root diameter with a
generally constant outer diameter with a thread that is narrow and sharp
throughout and an enlarged head portion capable of an interference fit to
the receiving holes of the plate. Instrumentation consists of plate
holders, a compression apparatus and a pilot hole forming device that
interlocks with the plate. Methods for spinal compression and bone hole
preparation are provided.
