1. A method comprising:
providing an anchor characterized by a center curve formed in an arcuate shape defining at any point thereon an axial direction therealong, a radial direction perpendicular thereto, and a circumferential direction circumscribing therearound, the anchor having a head (proximal) end and a point (distal) end with splines extending helically therebetween and radially away from the center curve to define and fit within a diameter thereof;
positioning the point end against a first bone structure;
engaging the anchor by a tool urging the point end into the bone by imposing a first force upon the head; and
fixing the anchor against withdrawal by progressing the anchor in the axial direction at the point end, guided by the splines along a combined arcuate direction along the center curve and helical direction along the splines.
