Abstract
A medical bone screw including a lock to lessen the possibility of pull-out or screw-out. The screw may be any bone screw including a cannula. A wire spring is inserted partially into the cannula prior to use. Once in position, the wire spring is pushed further down the cannula until its ends may project out side openings in the screw. These projections lock the screw in place. Further depression of the wire spring disengages them so the screw may be removed.
