Apparatus, system, and method for instrumentation

An osteotomy system for remediating a condition present in a patient, comprising:

• a resection guide comprising:
• one or more bone attachment features configured to couple the resection guide to a bone;
• and
• a resection feature that guides resection of the bone to dissect the bone into a proximal fragment and distal fragment;
• and
• a fixation guide comprising one or more openings that indicate a path for fasteners through the distal fragment and into the proximal fragment of the bone.

A method for performing a malleolar osteotomy, the method comprising:

• anchoring a resection guide to a surface of a long bone and proximal to a malleolus of the long bone, the resection guide comprising a bone engagement surface configured to register to the surface of the long bone;
• deploying one or more guide pins through the pin guide sleeves of a fixation guide and into the long bone;
• deploying fasteners coaxial with the openings;
• dissecting an osteotomy fragment from the long bone;
• retracting the osteotomy fragment inferiorly from the long bone to expose a portion of a talus, the osteotomy fragment including the malleolus;
• reducing the osteotomy fragment with the long bone;
• redeploying one or more guide pins into the one or more openings of the osteotomy fragment and the long bone;
• and
• deploying fasteners coaxial with the one or more openings to fix the osteotomy fragment to the long bone.
