Abstract:
1. A systematic displacement bone screw for maximizing bone displacement through a bone aperture which remains constant in size, comprising: a root; a plurality of bone compressing flanks extending outwardly from said root, each flank having a crest width; each flank separated from an adjacent flank by a flank spacing; a screw tip; a screw head; a major diameter that is constant along the length of the screw; a minor diameter that is constant along the length of the screw; wherein the crest width of each flank progressively increases from said screw tip to said screw head such that a flank with the smallest crest width is adjacent to said screw tip and a flank with the largest crest width is adjacent to said screw head; and wherein the flank spacing between adjacent flanks progressively decreases from said screw tip to said screw head.
