Abstract: A self-drilling bone screw, comprising a head, a threaded body, and a tip region. The threaded body extends vertically below the head and has a helical male threading. The tip region extends vertically below the treaded body. The tip region is fluted and has a pointed bottom tip, such that the tip region is configured to drill a hole into a bone and generate bone chips. The tip region further has a slot disposed horizontally through a portion of the tip region above the pointed bottom tip, the slot being configured to trap at least some of the bone chips, thereby enabling fusion between the bone and the bone chips. A diameter of threaded body is larger than a maximal diameter of the tip region.
