The threaded distal portion comprises a first full thread with a first constant diameter and a first constant pitch throughout the threaded distal portion, wherein an open end of the threaded distal portion forms a leading end of the bone screw. The threaded center portion comprises a second full thread with a second constant diameter and a second constant pitch throughout the threaded center portion, wherein the second constant diameter is the same as the first constant diameter, and the second constant pitch is smaller than the first constant pitch. The threaded proximal portion comprises a third full thread with a third constant diameter and a third constant pitch throughout the threaded proximal portion.
