1. An orthopedic fixation system for fusing a first bone and a second bone in a predetermined anatomical position, comprising:
an implant adapted to transition between an unconstrained shape and a constrained insertion shape;
an implant insertion device adapted to constrain the implant in its constrained insertion shape;
a drill guide including a first aperture and a second aperture therethrough that are spaced apart a preset distance corresponding with the implant in its constrained insertion shape;
first and second K-wires;
a cannulated drill bit;
the drill guide adapted to reside atop the first bone and the second bone across a fusion site thereof, whereby the first aperture of the drill guide is located at the first bone and the second aperture of the drill guide is located across the fusion site at the second bone;
the first K-wire adapted to insert through the first aperture of the drill guide and into the first bone, whereby manipulation of the drill guide leverages the first bone and the second bone into a conforming anatomical position, further whereby the first K-wire and the drill guide hold the first bone and the second bone to permit a verification of whether the conforming anatomical position corresponds with the predetermined anatomical position;
the second K-wire adapted to insert through the second aperture of the drill guide and into the second bone, whereby the first and second K-wires and the drill guide hold the first bone and the second bone in a retained anatomical position that corresponds with the predetermined anatomical position;
the cannulated drill bit adapted to fit over the first K-wire and to drill into the first bone until the cannulated drill bit creates a first drilled hole;
the cannulated drill bit adapted to fit over the second K-wire and to drill into the second bone until the cannulated drill bit creates a second drilled hole; and
the implant insertion device adapted to insert the implant into the first drilled hole and the second drilled hole whereby, after release of the implant from the implant insertion device, the implant attempts to transition from its constrained insertion shape to its unconstrained shape such that the implant continuously compresses the first bone and the second bone thereby holding the first bone and the second bone in the predetermined anatomical position.
