View Edit Delete	PER-8 PROV	As shown, the cutting guide 300 may have a body 310 with a monolithic construction and the general shape of a rectangular prism. The cutting guide 300 may further have a joint alignment feature that helps align the body 310 with the metatarsocuneiform joint between the first cuneiform 210 and the first metatarsus 230. The joint alignment feature may consist of a joint probe 320 that extends from the body 310 and has a blade-like shape. The body 310 may reside on the dorsal surfaces of the first cuneiform 210 and the first metatarsus 230, while the joint probe 320 may protrude into the metatarsocuneiform joint between the first cuneiform 210 and the first metatarsus 230 to provide proper alignment of the body 310 with the metatarsocuneiform joint.	68	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	According to one embodiment, a system may be provided for correcting a condition present in one or more bones of a patient’s foot. The system may have a cutting guide with a first bone engagement surface shaped to match a first contour on a first bone of the one or more bones, and a first guide feature that, with the first bone engagement surface overlying the first contour, is positioned to guide resection of the one or more bones as part of a surgical osteotomy for correcting the condition. The surgical osteotomy may be selected from a first group consisting of a bunion correction osteotomy, an Evans calcaneal osteotomy, and a medializing calcaneal osteotomy. The first bone may be selected from a second group consisting of a metatarsus, a cuneiform, and a calcaneus.	18	Added by DJM 7 2021	7/2/21, 12:00 AM

View Edit Delete	PER-8 PROV	The method may further include placing the cutting guide such that the first bone engagement surface overlies the first contour, and the second bone engagement surface overlies the second contour, securing the first bone attachment feature to the cuneiform, securing the second bone attachment feature to the metatarsus, using the first guide feature to guide motion of a cutter to resect the cuneiform, and using the second guide feature to guide motion of a cutter to resect the metatarsus.	10	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	The method may further include reorienting the metatarsus relative to the cuneiform and, after reorienting the metatarsus relative to the cuneiform, promoting fusion between the cuneiform and the metatarsus.	11	Added by DJM 7 2021	7/2/21, 12:00 AM

View Edit Delete	PER-8 PROV	Various bone conditions may be corrected through the use of 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 the cut. 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 performance of 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 7 2021	7/2/21, 12:00 AM
