A bone implant system

A bone anchor, comprising:

• a distal portion having a bone-cutting portion, and
• a proximal propeller portion comprising:
• a shaft having a rotational axis;
• helical threads positioned about a longitudinal portion of the shaft forming a plurality of helical root valleys between crests of the helical threads, and the helical threads having distal surfaces and proximal surfaces;
• a plurality of pawls projecting from the distal surfaces to create a turbine-like thread-form shape;
• wherein the plurality of pawls are angled with respect to the distal surfaces to allow for forward rotation of the threads and to resist backward rotation of the threads;
• a circumferential rim projecting from the proximal surface of the helical threads and wherein the proximal surfaces of the helical threads are curved in a concave manner, and
• an irregular lattice structure formed within the plurality of helical root valleys.

A method of placing an anchor in bony material, the method comprising:

• applying a torque to a proximal end of the anchor to rotate a propeller about the anchor's longitudinal axis in a rotational direction within a bony structure to propel the anchor in a longitudinal direction and resulting in a rotation of a plurality of pawls to compress the bony material while propelling the propeller forward;
• compressing bony material between a cupped proximal side of a first thread of the propeller and a distal side of a second thread of the propeller;
• and
• injecting a internal labyrinth defined in the propeller with bone-growth material such that the bone-growth material flows from an opening defined in a proximal portion of the anchor into a plurality of channels and out of a plurality of openings defined along a shaft of the anchor.
