Abstract
A bone fixation screw is provided for coupling with a bone fusion plate to join bone fusions. The bone fixation screw comprises a head portion and a shank that is comprised of distal threads and extends to a tapered portion and a rounded distal end. The head portion includes proximal threads extending circumferentially around an inferior end of the head portion. The proximal threads are configured to advantageously cross-thread with aperture threads of the bone fusion plate when the bone fixation screw is obliquely angled relative to the bone fusion plate. Slots disposed around the head portion allow the proximal threads to disengage and reengage with the aperture threads as the bone fixation screw turns. A shaped opening in a superior end of the head portion engagedly receives a tool for driving the bone fixation screw into a bone hole.
