Abstract
Bone plate systems and methods for implanting. A bone plate system includes a bone plate having a first surface, a second, bone contacting surface opposed to the first surface, and at least one aperture extending through the first and second surfaces. The system includes a bone screw having a threaded shank along a distal end portion thereof, the threaded shank configured to pass through the aperture. A dynamic member is configured to fit between portions of the screw and the bone plate and allow movement of the dynamic member and the screw relative to the bone plate in a first direction, while preventing movement of the dynamic member relative to the bone plate in a direction opposite to the first direction.
