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.
Claims1
A bone screw, comprising:
- an elongate shank defining a central longitudinal axis, the elongate shank having a proximal end, a distal end with a conical distal tip region that tapers distally inward, and a distal facing surface;
- and
- at least two threads formed on the elongate shank, each thread terminating at the distal end in a leading cutting edge positioned radially outward of the central longitudinal axis and defined by an intersection between a proximal-facing surface of the thread and the distal facing surface of the conical distal tip region.
