Abstract
A plate system and method comprising a plate and a screw having an integral resilient lock. The screw comprises a head that has a portion that is adapted to be compressible as it is screwed into bone using a tool. After the screw head is received in the plate and the tool is removed therefrom, the screw head decompresses or expands into a locking or receiving area, thereby locking the screw in the plate. The plate is adapted to have at least one or a plurality of detents or lips for cooperating with at least a portion of the screw head to retain the screw in the plate and prevent it from withdrawing therefrom.
