First Claim
Patent Images
1. A bone plate assembly for implantation in an anatomical body, comprised of:
- a bone plate having apertures sized greater in at least one dimension than bone screws received in the apertures, a screw retaining member having an aperture for receiving a member that fixes the screw retaining member to the bone plate, the screw retaining member covering at least a portion of the bone screws, wherein the aperture in the screw retaining member is asymmetrically shaped and sized greater in at least one dimension than a member received within the aperture fixing the screw retaining member to the bone plate, wherein when the assembly is implanted in an anatomical body, the bone screws and screw retaining member are movable in a path corresponding to the dimensions defined by the respective apertures.

Abstract
The present invention is directed to a bone plate assembly including a bone plate, bone screws received in apertures in the assembly, and a screw retaining member fixed to the bone plate which covers at least a portion of the bone screws. When bone screws have been received by the bone plate and inserted into bone and/or tissue, the bone plate assembly can be used to fuse anatomical structures together, such as adjoining bones, or to heal a fracture in bone.
