Abstract
Various bone screws configured to be implanted into bone and methods of use are provided. In an exemplary embodiment, a bone screw is provided with an elongate shank having at least two threads thereon, and having a distal facing surface with at least two cutting edges. The cutting edges can be configured to cut bone as the bone screw is rotated into bone, thereby forming a path for the threads.
