Abstract
A bone screw having a helical thread with a constant outside diameter and curling around a tapered core. The fine screw tip and thread at the tip of the screw can be inserted into a bone with minimal tearing or cracking of the bone. The thicker core just below the screw head increases the screw's ability to withstand compressive and distractive loads. The core is thickest just below the head because it is at that point on the screw that the fulcrum loads are greatest.
