1. An autograft forming bone anchor comprising:
an elongated anchor core having a tip at a distal end and a coupled to a head at a proximal end; and
a segmented helical thread defining one or more gaps therein, each gap defining at least a trailing wall, the trailing wall having a cutting surface including at least one cutting edge; wherein a plane of the cutting surface that extends through a point of contact of the cutting surface with the anchor core and the cutting edge, is angled at an angle (a) with respect to a radius (r) of the bone anchor, and
the cutting surface and the cutting edge are configured to cut bone and guide bone fragments radially inwards; wherein the bone cutting surface is curved inwardly at a radial dimension and at a longitudinal dimension thereof to form a concave, spoon-shaped geometry of the cutting surface.
