View Edit Delete	PER-8 PROV	According to some embodiments, a cutting guide may be provided for correcting a bunion present a patient’s foot. The cutting guide may have a first bone engagement surface shaped to match a first contour on cuneiform of the patient’s foot, and a second bone engagement surface shaped to match a second contour on a metatarsus of the patient’s foot. The cutting guide may further have a first slot that, with the first bone engagement surface overlying the first contour and the second bone engagement surface overlying the second contour, is positioned to guide resection of the cuneiform to define a first resected surface on the cuneiform. Further, the cutting guide may have a second slot that, with the first bone engagement surface overlying the first contour and the second bone engagement surface overlying the second contour, is positioned to guide resection of the metatarsus to define a second resected surface on the metatarsus. The first slot and the second slot may be positioned and oriented relative to each other such that, upon fusion of the cuneiform and the metatarsus between the first resected surface and the second resected surface, the bunion is at least partially corrected.	23	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	The system may further have an implant with a first bone-facing surface with a first shape that matches a first profile of a first resected surface of the first bone after resection of the first bone with the cutting guide, and a second bone-facing surface comprising a second shape that matches a second profile of a second resected surface of the first bone or a second bone of the one or more bones after resection of the first bone or a second bone with the cutting guide.	22	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	Thus, the result of the step 108 may be provision, to the surgeon, of one or more of the following: (1) one or more patient-specific instruments; (2) one or more patient-specific implants; (3) an instrument, selected from one or more available instrument sizes and/or configurations; (4) an implant, selected from one or more available implant sizes and/or configurations; (5) instructions for which instrument(s) to select from available instrument sizes and/or configurations; (6) instructions for which implant(s) to select from available implant sizes and/or configurations; (7) instructions for proper positioning or anchorage of one or more instruments to be used in the procedure; and (8) instructions for proper positioning or anchorage of one or more implants to be used in the procedure. These items may be provided to the surgeon directly, or to a medical device company or representative, for subsequent delivery to the surgeon.	51	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	The method 100 and the method 120 are merely exemplary. Those of skill in the art will recognize that various steps of the method 100 and the method 120 may be reordered, omitted, and/or supplemented with additional steps not specifically shown or described herein.	60	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	In a step 130, the manufactured cutting guide may be used in surgery to facilitate treatment of the condition. Specifically, the bone apposition surface of the cutting guide may be placed against the corresponding contours of the first cuneiform and the first metatarsus. The guide features (for example, slots) may then be positioned on either side of the joint between the first cuneiform and the first metatarsus to guide resection of the first metatarsus and the first cuneiform to remove the intervening joint. The cutting guide may then be removed, and the remaining portions of the first cuneiform and the first metatarsus may be placed to abut each other. The cutting guide may have been shaped such that the cuts made to the first cuneiform and the first metatarsus are properly oriented to bring the first metatarsus back into its proper orientation relative to the rest of the foot. The first cuneiform and the first metatarsus may be secured together through the use of a bone plate or the like. The surgical wound may be closed to allow the foot to heal, and to allow the first cuneiform and the first metatarsus to fuse together.	59	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	In a step 128, the model(s) may be used to manufacture patient-specific instrumentation and/or instruments. This may include manufacturing the cutting guide with the bone apposition surface and the guide features as described above. As in the step 108, the step 128 may additionally or alternatively involve provision of one or more instruments and/or implants from among a plurality of predetermined configurations or sizes. Further, the step 128 may additionally or alternatively involve provision of instructions for placement and/or anchorage of one or more instruments and/or instruments to carry out the procedure.	58	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	In a step 126, the CAD model and/or CT scan data may be used to model patient-specific instrumentation that can be used to correct the bunion deformity. Such instrumentation may include a cutting guide that is attachable to the first cuneiform and the first metatarsus, with two guide features that facilitate resection of the cuneiform and the metatarsus in preparation for arthrodesis. In some embodiments, performance of the step 126 may include modelling the cutting guide with a bone apposition surface that is shaped to match contours of the surfaces of the cuneiform and the metatarsus, such that the bone apposition surface can lie directly on the corresponding contours of the first cuneiform and the first metatarsus.	57	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	After the step 122 has been carried out, the method 120 may proceed to a step 124 in which a CAD model of the relevant portion of the patient’s anatomy is generated. The CAD model may optionally include the bones of the entire foot, like the CT scan obtained in the step 122. In alternative embodiments, the step 124 may be omitted in favor of direct utilization of the CT scan data, as described in connection with the step 104.	56	Added by DJM 7 2021	7/2/21, 12:00 AM
