Abstract
A faceted bone screw and a method for manufacturing the same includes a screw thread configuration having facets that are incorporated into one or more of the leading edge, trailing edge or root of the thread. The facets are generally made up of a plurality of transitioning peaks and valleys which vary the depth of the thread and are disposed in one or more locations throughout the threaded portion of the bone screw. The facets operate to reduce the torque required to drive the bone screw into bone, while at the same time operate to assist in anchoring the bone screw within the bone once inserted therein, and thereby reduce the possibility for the screw backing out after insertion.
