ABSTRACT:
An anterior cervical plate system consists of a base plate and a connecting plate movably connected to the base plate. The base plate can be inserted into any number of cervical vertebral bodies in any one construct. The base plate contains holes for two unicortical bone screws and a third hole to accommodate a rather large diameter, but short screw that movably secures the connecting plate, and raised middle portion to strengthen screw purchase and fit of the connecting plate. The connecting plate has a central trough opening to accommodate this screw.
