Abstract

Claims (38)

1 . 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.

2 . The system of claim 1 , wherein the first trajectory converges with the second trajectory at a vertex having a wedge angle, such that posterior resection feature and the anterior resection feature form a wedge osteotomy comprising a wedge bone fragment after formation of the first osteotomy and the second osteotomy, the wedge angle determined based, at least in part, on the bone model.

3 . The system of claim 2 , wherein the bone attachment feature is configured to secure the resection guide to a portion of the bone that forms the wedge bone fragment after formation of the wedge osteotomy.

4 . The system of claim 2 , wherein the vertex is prepositioned to be between a medial cortex of the bone and the resection guide when the resection guide is designed for the patient's foot.

5 . The system of claim 1 , wherein the medial side of the resection guide comprises a bone engagement surface configured to register to a lateral surface of the bone, the bone engagement surface defined based a lateral surface of the bone model and a planned position of the resection guide on a lateral surface of the bone.

6 . The system of claim 1 , wherein the at least one complementary component comprises the positioning guide and wherein the positioning guide comprises:

a body having an anterior side, a posterior side, a medial side, a lateral side, a dorsal side, and a plantar side;

an anterior alignment feature;

a posterior alignment feature; and

an offset feature on the medial side of the body, the offset feature configured to translate a posterior bone fragment relative to an anterior bone fragment, the posterior bone fragment and anterior bone fragment formed by way of one of the first osteotomy and the second osteotomy.

7 . The system of claim 6 , wherein the positioning guide comprises:

a bone engagement surface on the medial side, the bone engagement surface configured to register to a lateral surface of the posterior bone fragment and the anterior bone fragment; and

wherein the bone engagement surface is defined based on a lateral surface of the bone model and a planned reduced position of the posterior bone fragment and the anterior bone fragment.

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

at least one fastener configured to engage a phalanx of a patient's foot;

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 phalanx, a first trajectory for the first osteotomy determined based on a bone model of the phalanx based on medical imaging of the patient's foot, the bone model configured to significantly 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 phalanx, a second trajectory for the second osteotomy determined based on the bone model;

wherein the first trajectory converges with the second trajectory at a vertex within a bone of the patient;

a first bone attachment feature configured to secure the resection guide to the phalanx; and

a second bone attachment feature configured to secure the resection guide to the phalanx.

9 . The system of claim 8 , wherein at least one of the first bone attachment feature and the second bone attachment feature are configured to form a guide hole for a fastener within the phalanx when the at least one of the first bone attachment feature and the second bone attachment feature are disengaged from the phalanx.

10 . The system of claim 8 , wherein the first bone attachment feature is configured to form a first guide hole and the second bone attachment feature is configured to form a second guide hole and wherein the first guide hole is configured for a first leg of a bone staple and the second guide hole is configured for a second leg of the bone staple.
