View Edit Delete	PER-10	One general aspect of the present disclosure can include a method for making a patient specific cutting guide configured to mitigate a condition present in a patient. The method includes accessing a bone model of one or more bones of a patient based on the condition and/or the bone model; defining one or more guide features of a preliminary cutting guide model for an osteotomy procedure, the preliminary cutting guide model may include a superior surface and an inferior surface; defining at least a portion of the inferior surface of the preliminary cutting guide model according to a topographical surface of at least one bone of the bone model such that the inferior surface substantially matches a contour of the topographical surface; and where the preliminary cutting guide model is configured for fabrication of a patient specific cutting guide corresponding to the preliminary cutting guide model.	8	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Implementations may include one or more of the following features. The method may include defining one or more alignment features of the preliminary cutting guide model for the osteotomy procedure. Accessing the bone model further may include: modifying a bone model may include a first modeled bone and a second modeled bone of a joint of the patient such that the first modeled bone is rotated about a longitudinal axis of the first modeled bone from a first position to a second position; defining a first cut surface in the first modeled bone, where the first cut surface is perpendicular to the longitudinal axis of the first modeled bone; defining a first angle for a second cut surface of the second modeled bone, the first angle measured relative to the first cut surface and extends inferiorly away from the first cut surface; defining a second angle for the second cut surface of the second modeled bone, the second angle measured relative to the first cut surface and configured to mitigate the condition; modifying the bone model of the first modeled bone to include the first cut surface and the second modeled bone to include the second cut surface; and where the one or more guide features of a preliminary cutting guide model are configured to enable a surgeon to form the first cut surface and the second cut surface.	9	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Defining one or more guide features of the preliminary cutting guide model further may include: defining a first slot configured to guide formation of a first cut surface of a first bone of the patient corresponding to a first modeled bone; defining a second slot configured to guide formation of a second cut surface of a second bone of the patient corresponding to a second modeled bone; and where the first slot and second slot are positioned such that fixing the first cut surface of the first bone to the second cut surface of the second bone mitigates the condition. The method may include selecting the preliminary cutting guide model from a repository of template cutting guide models, each template cutting guide model configured for an osteotomy procedure configured to correct one of a plurality of conditions. The method may include defining a coupler configured to engage an alignment guide, the alignment guide configured to indicate a resulting alignment of patient body parts upon completion of the osteotomy procedure. The bone model is derived from patient imaging data generated while the patient places their weight on at least one joint involved in the osteotomy procedure.	10	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	One general aspect of the present disclosure can include a system for correcting a condition present in a patient. The system may include a cut guide that may include: a first guide feature configured to define a first cut surface configured for resection of a first metatarsal of a patient, a second guide feature configured to define a second cut surface configured for resection of a medial cuneiform of a patient, an inferior side may include a bone engagement surface shaped to match a first surface of the first metatarsal and a second surface of the medial cuneiform, a medial cuneiform alignment feature coupled to the medial cuneiform, where one of the first guide feature and the second guide feature is configured based on patient imaging data such that fusion of the first metatarsal at the first cut surface to the medial cuneiform at the second cut surface mitigates the condition. The system includes a first metatarsal alignment feature coupled to the first metatarsal, the first metatarsal alignment feature configured to enable a user to rotate the first metatarsal from a malrotation position to a desired rotation position; and a compressor/distractor configured to engage the medial cuneiform alignment feature and the first metatarsal alignment feature and compress the first cut surface of the first metatarsal against the second cut surface of the medial cuneiform.	11	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Implementations may include one or more of the following features. The system where: the first metatarsal alignment feature may include a pin guide configured to position alignment pins for a desired rotation angle of the first metatarsal about its longitudinal axis; the compressor/distractor may include a pair of legs that are closer to each other at distal end of each leg than at a proximal end of each leg.	12	Added by DJM 2 2022	2/25/22, 12:00 AM

View Edit Delete	PER-10	Various bone conditions may be corrected using an osteotomy, in which one or more bones are cut, replaced, and/or reoriented. Cutting guides are often used to help the surgeon properly locate, position, and make one or more cuts. Unfortunately, many known cutting guides are not patient-specific, and can be difficult to properly position to perform the osteotomy on a specific patient. Even if properly positioned, many known cutting guides are difficult to secure at the desired position, without moving away from the desired position prior to performing the osteotomy. As a result, many known osteotomy procedures carry risk of an improper cut that fails to correct the underlying condition, or even endangers surrounding tissues.	2	Added by DJM 2 2022	2/25/22, 12:00 AM
