These shape-memory alloy wire forms can be inserted into phalanx, metacarpal or metatarsal bones via a percutaneous technique. The technique uses small skin incisions; a specialized drill guide that has holding K-wires to maintain fixation of the drill guide to the bone so that it does not lose the insertion point; a specialized drill as well as a specialized wire cutter and advancement tool to make sure that the level of the wire is below the level of the outer cortical bone. Shape-memory alloy (e.g., Nitinol) based wires with a pre-bent curve have an advantage over the typical standard K-wire in that they can spring back to their predetermined memory shape when inserted into the intramedullary canal of the bone and heated, i.e., a more aggressive curve. By increasing their bending or flexion to increase the arc of curvature, this allows fixation points for the wire, essentially locking it to bone.11-05-2009
