ABSTRACT:
A dynamic cervical plate has a ratchet and pawl mechanism that allows the cervical plate to post operatively shorten the length of the plate and maintain compression between adjacent vertebrae. The plate has an elongated shaft with teeth on one surface and a groove along each longitudinal edge. A lateral plate is attached on one end of the shaft. The plate has screw holes for connecting with the head of a spinal screw. Another lateral plate is slidably engaged in the longitudinal grooves along the shaft and has a spring clip acting as a pawl with the teeth on the shaft. The lateral sliding plate has screw holes on each side of the shaft. The clip is configured to span the screw holes to automatically engage and prevent screws from backing out of the holes.
