20. An orthopedic fixation system, comprising:
an orthopedic implant transitionable between a natural shape and an insertion shape whereby a transition of the orthopedic implant from the natural shape to the insertion shape stores deliverable energy and a transition of the orthopedic implant from the insertion shape to the natural shape delivers stored energy, the orthopedic implant, comprising:
a bridge with a first end and a second end, the bridge being deformable to move the orthopedic implant between the natural shape and the insertion shape,
a claw extending from the bridge at the first end thereof, and
an anchor extending from the bridge at the second end thereof;
the orthopedic implant when transitioned to the insertion shape being adapted to affix a bone fragment and a bone, whereby:
the anchor is configured to implant in the bone,
the bridge is configured to extend over the bone and the bone fragment to position the claw at the bone fragment, and
the claw is configured to capture the bone fragment such that, upon an attempted transition of the orthopedic implant from the insertion shape to the natural shape, the orthopedic implant being adapted to deliver the energy stored therein to the bone fragment and the bone thereby affixing the bone fragment with the bone;
an implant delivery device, comprising a handle with a shaft extending therefrom, the shaft terminating in an implant grip configured such that, upon transition of the orthopedic implant from the natural shape to the insertion shape, the implant grip engages the bridge thereby constraining the bridge and holding the orthopedic implant in the insertion shape while the claw and the anchor extend from the implant grip; and
the implant grip, comprising:
first and second side walls and first and second end walls defining a cavity having an entrance,
a first resilient retention tab extending from the first side wall into the cavity at the entrance thereof, and
a second resilient retention tab extending from the second side wall into the cavity at the entrance thereof.
