Abstract

A bone screw including a head portion, a neck portion, and a shaft portion is provided. The shaft portion includes a first end, an opposite second end, a helical thread form, and a shank. The first end of the shaft portion is attached to the neck portion, and the helical thread form extends around the shank between the first end and the second end. The thread form terminates at a thread-termination surface adjacent the first end of the shaft portion, where the thread-termination surface affords an abrupt transition into the shank.
