Claim 16:
17. A compliant, self-anchoring screw with auxetic properties comprising:
a proximal screw head;
a screw shank extending distally from the screw head;
a plurality of blade flexures extending from the screw shank in a proximal direction at an angle relative to a longitudinal axis of the screw shank the plurality of blade flexures being linearly aligned to form at least two row of blade flexures along the screw shank;
a panel attached to each row of blade flexures; and
a screw thread positioned on an exterior surface of each panel the screw thread being continuous across all panels;
wherein the screw comprises a resting state and a loaded state, and
wherein the loaded state of the screw compresses each panel in a proximal direction relative to the screw head and the screw shank, such that each blade flexure bends inwards and compacts each panel inwards towards the screw shank.
