Abstract

Claims (23)

1 . A method for correcting a condition present in a patient's foot, the method comprising:

obtaining a bone model of one or more bones of a patient's foot;

using the bone model to generate a patient-specific cutting guide comprising:

a body configured to seat transverse to a plurality of joints, the body comprising:

a proximal side, a distal side, a medial side, a lateral side and a superior side;

an inferior side comprising a plurality of bone engagement surfaces shaped to match two surfaces of a first surface of a first bone, a second surface of a second bone, a third surface of a third bone, and a fourth surface of a fourth bone, wherein the first bone, the second bone, the third bone, and the fourth bone are bones of the plurality of joints of the patient's foot; and

one or more guide features positioned to guide resection of at least one of the first bone, the second bone, the third bone, and the fourth bone during an osteotomy;

an anchor feature coupled to the body and configured to receive one or more fasteners to anchor the body to at least one of the first bone, the second bone, the third bone, and the fourth bone;

using the patient-specific cutting guide in a surgical procedure to correct a condition present in the patient's foot.

2 . The method of claim 1 , wherein the patient-specific cutting guide comprises a plurality of anchor features, the plurality of anchor features comprising a proximal anchor feature extending proximally from the body and a distal anchor feature extending distally from the body.

3 . The method of claim 2 , wherein the proximal anchor feature anchors the body to the first bone and the distal anchor feature anchors the body to the fourth bone, the fourth bone diagonally adjacent to the first bone.

4 . The method of claim 2 , wherein the proximal anchor feature extends proximally from the body and dorsal to one of two bones on a proximal side of two adjacent joints and the distal anchor feature extends distally from the body and dorsal to one of two bones on a distal side of the two adjacent joints.

5 . The method of claim 4 , wherein the proximal anchor feature comprises a first hole that passes through the proximal anchor feature and the proximal anchor feature is configured to guide a fastener deployed through the first hole toward a longitudinal axis of one of two bones on a proximal side of the two adjacent joints, when the patient-specific cutting guide is in use.

6 . The method of claim 5 , wherein the distal anchor feature comprises a second hole that passes through the distal anchor feature and the distal anchor feature is configured to guide a fastener deployed through the second hole toward a longitudinal axis of one of two bones on a distal side of the two adjacent joints, when the patient-specific cutting guide is in use.

7 . The method of claim 1 , wherein the anchor feature comprises a guide for at least one of a K-wire and a pin into a bone and wherein the one or more guide features are configured to be patient-specific.

8 . The method of claim 7 , wherein the body comprises a longitudinal axis that extends from a medial side of the body to a lateral side of the body and wherein at least one the one or more guide features are positioned at a first angle relative to the longitudinal axis, the first angle within a transverse plane of a patient's foot and the first angle determined at least in part by the bone model.

9 . The method of claim 8 , wherein the patient-specific cutting guide comprises:

a first guide feature that extends between a medial side of the patient-specific cutting guide and a lateral side of the patient-specific cutting guide, the first guide feature being coincident with the longitudinal axis;

a second guide feature extends between the medial side and the lateral side and positioned between the first guide feature and a distal side of the patient-specific cutting guide; and

wherein the second guide feature extends away from the first guide feature at the first angle on the superior side of the patient-specific cutting guide.

10 . The method of claim 9 , wherein:

the first guide feature extends from the superior side to the inferior side at a first orientation perpendicular to a longitudinal axis of one of one of the first bone, the second bone, the third bone, and the fourth bone; and

the second guide feature extends from the superior side to the inferior side at a second orientation that intersects the longitudinal axis of the one of one of the first bone, the second bone, the third bone, and the fourth bone at a second angle defined based at least in part on patient imaging data.
