OG exemplary drawing
 
1. A kit for correcting alignment between a first bone and a second bone by fusing a joint between the first bone and the second bone, the kit comprising:
a first guide comprising:
a first end portion having a first cannula aligned along a first axis;
a second end portion having a second cannula aligned along a second axis, the first axis being non-parallel with the second axis;
wherein the first guide is configured such that inserting a first k-wire through the first cannula intersects the first bone and inserting a second k-wire through the second cannula intersects the second bone when the first and second bones are in a deformed configuration;
a second guide comprising:
a first end portion having a first cannula; and
a second end portion having a second cannula, the first cannula being parallel with the second cannula, wherein the first cannulas of the first and second guides have a respective first same diameter, and the second cannulas of the first and second guides have a respective second same diameter;
wherein the second guide is configured such that when the first k-wire is fixed within the first bone and the second k-wire is fixed within the second bone in the deformed configuration, sliding the second guide over first and second k-wires, with the first and second k-wires being received within the respective first and second cannula of the second guide, re-aligns the first and second bones into a corrected configuration, and
wherein the first guide and the second guide are separate structures.
