AWL-TIPPED PEDICLE SCREW AND METHOD OF IMPLANTING SAME

摘要

A bone screw and method of inserting the same is disclosed. In one example, the bone screw includes an awl tip for creating a pilot hole in the pedicle of a vertebra without having to predrill a starter hole. One or more threads located adjacent to the awl tip engage the wall of the pilot hole and draw the screw into the bone, thereby eliminating the need to drill and tap a hole in the bone prior to implantation of the screw.
