Apparatus, system, and method for generating patient-specific implants and/or instrumentation for osteotomies

An osteotomy system for remediating a bone condition present in a patient's foot, the system comprising:

• a resection guide comprising:
• a body having an anterior side, a posterior side, a medial side, a lateral side, a dorsal side, and a plantar side;
• a posterior resection feature configured to guide a cutting tool to form a first osteotomy in the bone, the posterior resection feature extending through the resection guide from the lateral side to the medial side along a first trajectory at least partially determined based on a bone model of at least a portion of the patient's foot, the bone model based on medical imaging of the patient's foot and configured to resemble the anatomy of the patient's foot;
• an anterior resection feature configured to guide a cutting tool to form a second osteotomy in the bone, the anterior resection feature extending through the resection guide from the lateral side to the medial side along a second trajectory at least partially determined based on the bone model;
• wherein the first trajectory converges with the second trajectory at a vertex having a position determined before fabrication of the resection guide;
• a bone attachment feature configured to secure the resection guide to the bone;
• and
• at least one complementary component selected from the group consisting of:
• an alignment guide;
• a rotation guide;
• a compression guide;
• a correction guide;
• a positioning guide;
• a pin guide;
• and
• a fixation guide.
