Abstract
A bone plate system is provided. The system includes two or more fastener locks stacked on top of each other and located between two holes in a plate adapted to receive bone fasteners. An actuator is provided between the locks. As the actuator is advanced, the locks are moved sequentially into position, firstly, to prevent one or more bone fasteners from backing out of the plate while permitting the fasteners to angulate and, secondly, to lock the angulation of the bone fasteners while still providing back out protection in situ. An expandable bone plate having a top plate interconnected to a bottom plate by a rack and pinion is provided. The rotation of the pinion with a driver lengthens or shortens the plate incrementally for custom length adjustment. The length is fixed in position with the simple removal of the driver and no further step is required to lock the plate length.
