Abstract
A bone screw is disclosed. A head includes a driver-receiving element formed thereon. A shank having a proximal portion, which is integrally connected to the head, and a distal portion maintains a constant diameter from the proximal portion to the distal portion. Three helical threads extend around the shank from the proximal portion to the distal portion. The three helical threads are symmetrically and helically aligned and advance uniformly along the length of the shank for each revolution to define a thread depth that remains constant along the length of the shank. The three helical threads respectively include three leads, which are offset by approximately 120° from each another. A tip is integrally connected to the distal portion of the shank and the tip intersects with a flute to define a self-tapping point.
