Abstract

A bone screw includes a main body having a proximal end and a distal end. The main body extends along a longitudinal axis. The main body has an externally threaded surface that includes at least one helically extending thread having a minor diameter and a major diameter, which major diameter is greater than the minor diameter. The thread includes at least two flank surfaces extending between the minor diameter and the major diameter. The minor diameter of the thread defines a central portion of the main body. The thread may include at least one aperture that extends along an aperture axis through the thread between the flank surfaces.
