A patient specific instrument is disclosed for correcting a condition present in a patient. The patient specific instrument includes a body that includes an inferior side having a bone engagement surface shaped to match a first surface of a first bone and a second surface of a second bone of a joint. The instrument also includes a superior side having a first guide feature and a second guide feature that together, with the bone engagement surface overlying the first surface and the second surface, are positioned to guide resection of the first bone and the second bone during a surgical osteotomy for correcting the condition. The body is configured to seat transverse to the joint with the bone engagement surface engaging the first surface of the first bone and the second surface of the second bone.

A surgical method surgical method includes collecting a set of patient data, identifying at least one significant point from the set of patient data, creating a surgical guide based on the at least one significant point and the patient data, and coupling the surgical guide with a calcaneum of a patient. The surgical method also includes performing at least one cut into the calcaneum using the surgical guide, wherein the at least one cut forms a recess in the calcaneum and defines a first calcaneal portion positioned substantially anteriorly from the recess and a second calcaneal portion positioned substantially posteriorly from the recess, shifting at least one of the first calcaneal portion and the second portion in a medial direction by placing an implant at least partially within the recess, and coupling the implant with the first calcaneal portion and the second calcaneal portion.

The present invention relates to a guide module having oblique installation pins, the guide module including: a first installation pin unit penetratively inserted into one side of an aligned bone; a second installation pin unit penetratively inserted into the other side of the aligned bone; a reposition guide unit simultaneously penetrated by the first installation pin unit and the second installation pin unit and being simultaneously in contact with one side of the aligned bone and the other side of the aligned bone; and a compression guide unit disposed adjacent to the reposition guide unit and simultaneously penetrated by the first installation pin unit and the second installation pin unit, in which imaginary central axes of holes of the reposition guide unit penetrated by the first installation pin unit and the second installation pin unit are spaced apart, at a predetermined interval in a vertical direction, from imaginary central axes of holes of the compression guide unit. Therefore, the aligned bone may be compressed.

A system of this invention is directed to a bone cutting support system that properly indicates a bone cutting plane determined in advance to a doctor during surgery. The bone cutting support system includes a storage that stores 3D shape data of a surgery target bone in association with position data of a marker fixed to the surgery target bone, a bone cutting plane determiner that determines, based on the 3D shape data of the surgery target bone, a position and direction of a bone cutting plane or a bone cutting guide plane representing a plane to guide for cutting the surgery target bone, and a bone cutting plane display that displays the determined bone cutting plane based on an image obtained by capturing the marker fixed to the surgery target bone.

A bone positioning guide may be used as part of a bunion correction procedure. The bone positioning guide can include a bone engagement member configured to be positioned on a medial side of a first metatarsal of a foot and a tip separated from the bone engagement member by a distance effective to position the tip on a lateral side of a second metatarsal and in an intermetatarsal space between the second metatarsal and a third metatarsal. The bone positioning guide can also include a mechanism operable to reduce the distance between the bone engagement member and the tip, thereby causing the first metatarsal to move in at least a transverse plane to reduce an intermetatarsal angle between the first metatarsal and the second metatarsal.

A cutting guide for spinal osteotomy comprises a main body having a first and a second arm, each provided with a respective through slot. The first and second arm are preferably inclined with respect to each other to substantially form a V shape. The guide also comprises a distal surface and a proximal surface shaped according to the anatomy of the specific patient and a height of each arm is also shaped according to the anatomy of the specific patient.

A surgical guide includes a first guide arm extending from a first end to a second end on a first longitudinal axis. The first guide arm defines a first plurality of openings sized and configured to receive a first guide element therethrough. A second guide arm extends from a first end to a second end on a second longitudinal axis. The second guide arm defines a second plurality of openings sized and configured to receive a second guide element therethrough. A pivot element couples the first end of the first guide arm to the first end of the second guide arm such that an angular distance between the first guide arm and the second guide arm can be adjusted in a first plane.

An orthopedic device for a shoulder joint includes a patient-specific alignment guide. The alignment guide includes a cap having a three-dimensional engagement surface customized in a pre-operative plan by computer imaging to be complementary and closely mate and conform to a humeral head of a proximal humerus of a patient. The alignment guide includes a tubular element extending from the cap and defining a longitudinal guiding bore for guiding an alignment pin at a patient-specific position and orientation determined in the pre-operative plan, and an orientation feature on the cap. The orientation feature is designed to orient the cap relative to the humeral head when the orientation feature is aligned with a landmark of the proximal humerus.
