Abstract
Embodiments of the invention may prevent or diminish a bone screw from “backing out” from bone. Bone particulate residing in channels of the bone screw may promote bone growth that would reduce the potential of backing out. Furthermore, bone particulate from drilling and tapping functions can cause increased friction. However, by placing bone particulate in channels of the bone screw, potential binding may be reduced resulting in less stress on the screw shaft. Also, breaking of screws during screw insertion may be reduced due to tapering of the screw.
