Abstract
A bone screw, comprising a proximal end and a distal end spaced from the proximal end in a distal direction along a longitudinal axis of the bone screw and a cannulation extending from the proximal end to the distal end. The bone screw further including a threaded region extending along at least a portion of a length of the screw, the length extending from the proximal end to the distal end. The threaded region defining at least one external thread that extends about the longitudinal axis along a helical path. The threaded region includes at least one flute that extends to the distal end of the bone screw. The at least one flute defines an associated at least one cutting tooth that, in turn, defines a cutting face oriented so as to define an angle with respect to the longitudinal axis. The angle is in the range of about 5 degrees and about 25 degrees, and the flute circumferentially interrupts at least a portion of the external thread.
