    Abstract: A bone screw removal system for a bone screw retaining system that includes an implant having a plate, which defines a plurality of transversely extending bores that are configured to receive a bone screw for engaging the plate to the cervical spine, and an elastically deformable spring member positioned therein a cavity of the plate such that portions of the spring member can extend into a portion of an upper region of each of the bores of a pair of opposing bores, the spring member being movable between a first relaxed, expanded position and a second, compressed position. The bone screw removal system having at least one tongue member that is configured to selectively act on the spring member of the bone screw retaining system.
