A bone fixation system includes a bone screw having a longitudinal axis. A passage in the bone screw extends along the longitudinal axis and has a proximal opening at the proximal end of the bone screw and a distal opening at a distal end of the bone screw. A drill extends through the passage, a first end of the drill extending out the distal opening. The combination of the bone screw and the drill is self-drilling.
