Abstract
A cervical plate assembly is disclosed. The cervical plate assembly includes a base plate including: (1) at least two bone screw seats, each bone screw seat including a borehole dimensioned to receive a bone screw, and (2) a first blocking seat positioned between the at least two bone screw seats. The cervical plate assembly includes a blocking mechanism retained within the first blocking seat of the base plate. The blocking mechanism is selectively positionable between a closed position in which the blocking mechanism obstructs at least one bone screw seat to retain a bone screw with the base plate, and an open position in which the bone screw seats are unobstructed.
