PER-20 For example, the second distal resection guide 820b may be configured to guide resection of the first metatarsal 208 at an angle that extends more distal from a proximal end of the first metatarsal 208 than a metatarsal resection feature of the first distal resection guide 820b. In this manner, a surgeon has flexibility to change a preoperative plan as circumstances during the surgery indicate a need to do so, for example based on a condition and/or allowances of soft tissue of the patient. 316 Added by DJM Jan 2024 1/6/24, 10:06 PM

PER-20 Those of skill in the art will appreciate that embodiments of the system disclosed herein can be used on humans and animals and on bones that are relatively small in comparison to other bones of the body (e.g., bones of the foot and hand). Advantageously, the embodiments of the system seek to minimize the number of fasteners or pins placed within the bones of a patient by planning a surgical procedure such that pins or fasteners placed in one stage are and/or can be reused in subsequent stages. Consequently, pins initially deployed can remain in the bone or bone fragment as instruments are deployed and/or subsequent stages of the surgical procedure are performed. 318 Added by DJM Jan 2024 1/6/24, 10:06 PM

PER-20 In one embodiment, FIG. 14F illustrates a stage in which a positioning guide 1200 has been slid 1318 over the set of proximal guide pins 928 and the set of distal guide pins 930 until the positioning guide 1200 contacts the medial cuneiform 202 and the first metatarsal 208. This sliding action of the positioning guide 1200 causes unaligned guide pins to move into alignment which causes a cut face of the osteotomy of the cuneiform 202 to contact a cut face of the osteotomy of the metatarsal 208. FIG. 14F illustrates that deployment of the positioning guide 1200 has repositioned one or more of the medial cuneiform 202 and the first metatarsal 208 such that the bones are now reduced and in a state prepared for fixation. In certain embodiments, a surgeon may use flouroscopy to confirm the reduction. In certain embodiments, the deployment of the positioning guide 1200 may also apply compression for facilitating a union of the two bones. FIG. 14F also illustrates an example bone plate 810c that may be next be deployed 1320 to secure and/or connect the resected medial cuneiform 202 to the resected first metatarsal 208. 317 Added by DJM Jan 2024 1/6/24, 10:06 PM

PER-20 Referring still to FIG. 14E, in certain embodiments, a surgeon may decide to change the corrective surgical procedure intraoperatively or for another reason decide to use a different distal resection guide 820b than the one originally planned. For example, suppose a surgeon wants to create an osteotomy of the first metatarsal 208 that is at a greater or lesser angle that that of the originally planned distal resection guide 820b. In such an instance, the proximal resection guide 820a may be referred to as a first distal resection guide 820b and a surgeon may replace the first distal resection guide 820b with a second distal resection guide 820b configured to guide resection of the first metatarsal 208 at a different angle than the first distal resection guide 820b. The second distal resection guide 820b may include a second metatarsal resection feature different from a metatarsal resection feature of the first distal resection guide 820b. 315 Added by DJM Jan 2024 1/6/24, 10:06 PM

PER-20 In one embodiment, FIG. 14E illustrates a stage in which a distal resection guide 820b has been slid 1314 over the set of distal guide pins 930 until the distal resection guide 820b contacts the first metatarsal 208. Those of skill in the art will appreciate that in certain embodiments prior to deploying the distal resection guide 820b a surgeon may remove the proximal resection guide 820a. The distal resection guide 820b is securely in a desired location for an osteotomy of the first metatarsal 208. Next a surgeon may operate the distal resection guide 820b by inserting 1316 a cutting tool such as a rectangular oscillating blade attached to a manual, mechanical, pneumatic, or electric driver into a resection feature to cut the first metatarsal 208 for the osteotomy. 314 Added by DJM Jan 2024 1/6/24, 10:06 PM

PER-20 In one embodiment, FIG. 14D illustrates a stage in which a proximal resection guide 820a has been slid 1310 over the set of proximal guide pins 928 until the proximal resection guide 820a contacts the medial cuneiform 202. The proximal resection guide 820a is securely in a desired location for an osteotomy of the medial cuneiform 202. Next a surgeon may operate the resection guide 800a by inserting 1312 a cutting tool such as a rectangular oscillating blade attached to a manual, mechanical, pneumatic, or electric driver into a resection feature to cut the medial cuneiform 202 for the osteotomy. 313 Added by DJM Jan 2024 1/6/24, 10:06 PM

PER-20 In one embodiment, FIG. 14C illustrates the TMT after method step 1308 is completed. The navigation guide has been removed. The set of proximal guide pins 928 are positioned in the medial cuneiform 202 and the set of distal guide pins 930 are positioned in the first metatarsal 208. The initial and accurate positioning of the set of proximal guide pins 928 and the set of distal guide pins 930 can be an important step in a surgical procedure because other steps and/or instruments may rely on accurate positioning of these pins to perform their respective desired functions and aspects. A surgeon can now proceed with the procedure with confidence that the reference features will provide accurate guidance that corresponds to the preplanned and desired correction, based on the medical imaging of the patient’s foot. 312 Added by DJM Jan 2024 1/6/24, 10:06 PM

PER-20 FIG. 14B illustrates a stage in the surgical procedure in which the navigation guide has been placed in a desired position across the TMT. Advantageously, a surgeon may leverage a bone engagement surface and/or bone engagement opening of the navigation guide to position the navigation guide where needed. Once the navigation guide is in place, a surgeon deploys 1304 a set of proximal guide pins 928 into a set of proximal holes 924 and a set of distal guide pins 930 into a set of distal holes 926. In this manner, markers of the navigation guide have been used to position the set of proximal guide pins 928 (a proximal reference feature on a medial cuneiform 202) and the set of distal guide pins 930 (a distal reference feature on a first metatarsal 208). In one embodiment, before deploying the set of proximal guide pins 928 and set of distal guide pins 930, a surgeon may use fluoroscopy to check the position of the navigation guide relative to the parts of the bone. Advantageously, at this stage the set of proximal guide pins 928 and the set of distal guide pins 930 are positioned for use in subsequent stages. Next, a surgeon may operate 1306 a coupler or severe a frangible portion of the navigation guide to separate the set of proximal guide pins 928 from the set of distal guide pins 930 and remove 1308 the navigation guide. In one embodiment, a surgeon may remove the bolt 962 to operate the coupler. 311 Added by DJM Jan 2024 1/6/24, 10:06 PM

PER-20 FIG. 14A illustrates a stage of the method 1300 in which a navigation guide (e.g., navigation guide 840, navigation guide 900, navigation guide 1000) is being deployed 1302 onto a TMT between a medial cuneiform 202 and a first metatarsal 208. In the illustrated embodiment, the surgeon has made an incision that permits placement of the navigation guide 840 on a first TMT of a patient. The set of proximal guide pins 928 and set of distal guide pins 930 are also illustrated and will be deployed shortly. 310 Added by DJM Jan 2024 1/6/24, 10:06 PM

PER-20 Method 1300 may include additional implementations, such as any single implementation or any combination of implementations described below and/or in connection with one or more other methods or processes described elsewhere herein. In a first implementation, the distal resection guide may include a first distal resection guide configured such that sliding the first distal resection guide further may include replacing the first distal resection guide with a second resection guide. The second resection guide may be configured to guide resection of the metatarsal at an angle that extends more distal from a proximal end of the metatarsal than the metatarsal resection feature of the first distal resection guide. 307 Added by DJM Jan 2024 1/6/24, 10:06 PM
