Osteotomy Fixation Device and Related Systems and Methods

An osteotomy system comprising:

• (a) a fixation and guide device attachable to a target bone, the fixation and guide device comprising:
• (i) a device body comprising:
• (A) a bone attachment structure;
• and
• (B) a guide coupling structure comprising a rod rotatably associated with the coupling structure;
• (ii) a movable cutting guide threadably coupled to the rod;
• and
• (ii) a slot body removably attachable to the device body, wherein the slot body comprises a transverse slot defined within the slot body;
• and
• (b) a fixation plate attachable to a portion of the target bone after removal of the slot body.

A method of performing an osteotomy, the method comprising:

• positioning an osteotomy device adjacent to a target bone, the osteotomy device comprising:
• (a) a device body comprising:
• (i) a bone attachment structure;
• and
• (ii) a guide coupling structure comprising a rod rotatably associated with the coupling structure;
• (b) a movable cutting guide threadably coupled to the rod;
• and
• (c) a slot body removably attachable to the device body, wherein the slot body comprises a transverse slot defined within the slot body;
• inserting a first anchoring pin through the transverse slot and into the target bone;
• inserting a second anchoring pin through an opening defined in the bone attachment structure and into the target bone;
• making a desired cut in the target bone with a saw blade positioned against the movable cutting guide, resulting in a base bone and a cut bone;
• inserting a transposition mechanism through the movable cutting guide and into the cut bone;
• urging the cut bone distally from the base bone by rotating the rod associated with the coupling structure;
• urging the cut bone laterally by actuating the transposition mechanism;
• urging the cut bone proximally into contact with the base bone by rotating the rod associated with the coupling structure;
• removing the slot body from the device body;
• and
• attaching a fixation plate to the cut bone and the base bone.
