Screw and driver system and associated methods

An orthopedic screw and driver system, comprising:

• an orthopedic screw having an elongate body extending axially along a longitudinal axis from a screw distal end to a screw proximal end, the screw having a non-circular canula extending from the screw distal end to the screw proximal end;
• and
• a driver having a driver elongate body, a sleeve, and a K-wire;
• wherein the driver elongate body extends axially along a longitudinal axis from a driver elongate body distal end to a driver elongate body proximal end, the driver elongate body having a driver elongate body passageway extending from the elongate body distal end towards the elongate body proximal end;
• wherein the sleeve extends axially along a longitudinal axis from a sleeve distal end to a sleeve proximal end, the sleeve having a sleeve passageway extending from the sleeve distal end to the sleeve proximal end, the sleeve having a sleeve non-circular exterior surface complimentary to the driver elongate body passageway and the non-circular canula of the orthopedic screw, the sleeve being disposed in the driver elongate body passageway, and
• wherein the K-wire extends axially along a longitudinal axis from a K-wire distal end to a K-wire proximal end, the K-wire having a K-wire first portion and a K-wire second portion, the K-wire first portion having a non-threaded tip, the K-wire second portion being complimentary to the sleeve passageway, the K-wire disposed in the sleeve passageway.

A method of using a driver to insert an orthopedic screw into a bone comprising:

• inserting a distal end of a K-wire at an insertion point in a bone, the K-wire defining a non-circular circumferential surface;
• drilling a hole in the bone with the K-wire;
• passing an orthopedic screw over a proximal end of the K-wire, the orthopedic screw defining a lumen and having an interior, non-circular circumferential surface that is complimentary and mating with the non-circular circumferential surface of the K-wire;
• placing an elongate body on the proximal end of the K-wire, the elongate body defining a lumen and having an interior, non-circular circumferential surface that is complimentary and mating with the non-circular circumferential surface of the K-wire;
• rotating the elongate body to rotate the K-wire and the orthopedic screw and drive the orthopedic screw into the bone;
• while rotating the elongate body, pushing the elongate body distally while the distal end of the elongate body contacts a proximal end of the orthopedic screw;
• removing the elongate body and the K-wire from the bone, leaving the orthopedic screw in the bone.
