Abstract
In some embodiments, a cervical plate may include an elongate plate which bridges, during use, substantially adjacent vertebrae by anchoring the plate to the vertebrae. The cervical plate may include a plurality of openings extending through the elongate plate. The cervical plate may include plurality of bone fasteners. The bone fasteners may include a head and a shaft. The shaft may be positionable, during use, in the opening such that the shaft engages, during use, at least one of the vertebrae such that the bone fasteners couple the elongate plate to the vertebrae. The cervical plate may include a securing mechanism. The securing mechanism may, when activated, inhibit removal of at least one of the bone fasteners and inhibit movement of at least the shaft of the bone fastener in a lateral direction, while allowing movement of at least the shaft of the bone fastener along a substantially sagittal plane.
