View Edit Delete	PER-24	As shown in FIG. 16, method 1600 may include positioning a tibial resection guide onto an anterior surface of a distal end of the tibia. The tibial resection guide includes a body having an anterior side, a posterior side, a medial side, a lateral side, a superior side, and an inferior side; a tibia resection feature configured to guide a cutting tool to prepare the tibia for fusion to a talus; a tibial bone attachment feature configured to secure the tibial resection guide to the tibia; a bone engagement feature having a bone engagement surface configured to at least partially match a contour of a portion of the anterior surface of the distal end of the tibia when the tibial resection guide is positioned for use. The tibial resection guide is defined based at least partially on user directions and at least partially on a bone model of at least a portion of the tibia, the bone model based on medical imaging of a patient’s foot (block 1602). For example, a surgeon may position a tibial resection guide onto an anterior surface of a distal end of the tibia, as described above.	348	Added by DJM Jan 2024	1/6/24, 10:01 PM

View Edit Delete	PER-24	As further shown in FIG. 16, method 1600 may include deploying an alignment guide that includes a shaft directed towards a proximal end of the tibia (block 1606).	350	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	As also shown in FIG. 16, method 1600 may include inserting the cutting tool into the tibia resection feature and cutting the tibia to form a first osteotomy (block 1608).	351	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	As further shown in FIG. 16, method 1600 may include positioning a talus resection guide onto an anterior surface of the proximal end of the talus. The talus resection guide includes: a body having an anterior side, a posterior side, a medial side, a lateral side, a superior side, and an inferior side; a talus resection feature configured to guide the cutting tool to prepare the talus for fusion to the tibia; a talus bone attachment feature configured to secure the talus resection guide to the talus; a bone engagement feature having a bone engagement surface configured to at least partially match a contour of a portion of the anterior surface of the proximal end of the talus when the talus resection guide is positioned for use; where the talus resection guide is defined based at least partially on user directions and at least partially on a bone model of at least a portion of the talus, the bone model based on medical imaging of the patient’s foot (block 1610). For example, a surgeon may position a talus resection guide onto an anterior surface of the proximal end of the talus, as described above.	352	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	As also shown in FIG. 16, method 1600 may include deploying a set of fasteners as part of the talus bone attachment feature to secure the talus resection guide to the talus (block 1612).	353	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	As further shown in FIG. 16, method 1600 may include inserting the cutting tool into the talus resection feature and cutting the talus to form a second osteotomy (block 1614).	354	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	As also shown in FIG. 16, method 1600 may include deploying fixation across the first osteotomy and the second osteotomy to enable fusion of the tibia and the talus (block 1616).	355	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Method 1600 may include additional implementations, such as any single implementation or any combination of implementations described herein and/or in connection with one or more other methods or processes described elsewhere herein. A first implementation, method 1600 further includes accessing an anterior surface of a distal end of a tibia and an anterior surface of a proximal end of a talus of a patient’s foot; deploying a set of stops within the tibia resection feature to manage the cutting tool; verifying the position of the tibial resection guide by comparing the shaft to a mechanical axis of the tibia and a set of fasteners deployed using the tibial resection guide; and reducing the first osteotomy and the second osteotomy by abutting the resected distal end of the tibia and the resected proximal end of the talus. When verifying the position, the surgeon may leverage one or more shafts 878 positioned in one or more alignment guides 874, one or more bone attachment features 828 (i.e., pins in bone), and/or one or more resection guards 870 (e.g., reference features) that may be configured to have a trajectory and/or orientation relative to axes of bones of the patient’s foot such that a surgeon can used these reference features to verify that instruments are desired positions.	356	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Although FIG. 16 shows example blocks or steps of a method 1600, in some implementations, a method 1600 may include additional steps, fewer steps, different steps, or differently arranged steps than those depicted in FIG. 16. Additionally, or alternatively, two or more of the steps of a method 1600 may be performed in parallel.	357	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	In one embodiment, the present disclosure can include an alternative method to the method 1600 and/or a separate method which includes: obtaining a prescription for an osteotomy system and/or for a component of an osteotomy system. The alternative method may include modifying an instrument model of an instrument to be included in the osteotomy system. In one embodiment, the modifications to the instrument model may be made based on or due to or at least in response to a received prescription. Next the alternative method, may include sending a report, a message, a notification, a set of models that includes a bone model and/or a model of one or more instruments of the osteotomy system, or the like to a surgeon who issued the prescription for review by the surgeon. The surgeon may then provide feedback in response to the report, a message, a notification, a set of models that includes a bone model and/or a model of one or more instruments of the osteotomy system, or the like. Optionally, the alternative method may include implementing any feedback provided by the surgeon. Of course, the method could iterate with more notices of changes to the surgeon and feedback provided by the surgeon, until a satisfactory design (i.e., approved by the surgeon) is generated. Next, the alternative method could conclude by arranging for and/or fabricating the osteotomy system and/or components of the osteotomy system.	358	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	FIGS. 17A-17E illustrate different views of one or more stages in a surgical procedure that includes one or more embodiments of the present disclosure. Reference is made to FIGS. 8-10F, 12A-12D and FIG. 16.	359	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	FIG. 17A illustrates a stage of the method 1600 in which a tibial resection guide 822 is positioned 1602 on an anterior surface of a distal end of a tibia 226. In one embodiment, the tibial resection guide 822 and/or talus resection guide 824 may be made of metal such that they have a greater mass than resection guides 820 fabricated from materials having a lower mass such as polymers and/or ceramics. Using a resection guide 820 with a greater mass can facilitate registering the resection guide 820 to a bone surface during positioning steps.	360	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	In the illustrated embodiment, the surgeon has made an incision that permits access to an anterior surface of a distal end of a tibia and an anterior surface of a proximal end of a talus of a patient’s foot. Pins of two bone attachment features 828 (e.g., one or more tibial bone attachment features) have also been deployed to secure the tibial resection guide 822 to the tibia 226. Note that the tibial resection guide 822 includes an alignment guide 874, but the shaft 878 has not yet been inserted.	361	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	FIG. 17B illustrates a stage in the surgical procedure in which the shaft 878 is inserted in the alignment guide 874. A surgeon has deployed the alignment guide 874 according to one embodiment. A surgeon can now visually check manually, and/or with flouroscopy, a position of the tibial resection guide 822 in relation to a mechanical axis 880 of the tibia 226. In the illustrated embodiment, the surgeon has also deployed a plurality of resection guards 870.	362	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	FIG. 17C illustrates a lateral view with the fibula 228 and tibia 226 transparent. This illustrates a view a surgeon can take using the resection guards 870 and/or shafts 878 in relation to the mechanical axis 880. Advantageously, a surgeon can check the position, alignment, and/or trajectories in all three planes before performing a first osteotomy. In this manner, the surgeon can confirm that the osteotomy will be where intended and planned.	363	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	In one embodiment, FIG. 17D illustrates the ankle joint after method step 1610 is completed. Those of skill in the art will appreciate that the surgeon may opt to deploy the talus resection guide 824 prior to forming a first osteotomy using a cutting tool. Alternatively, or in addition, the surgeon may insert a cutting tool into a tibia resection feature 864 and cut the tibia 226 to form a first osteotomy prior to positioning a talus resection guide 824.	364	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Once the example talus resection guide 824 is positioned, a surgeon may deploy a set of fasteners/pins as part of one or more bone attachment feature 828 (e.g., one or more talus bone attachment features) to secure the example talus resection guide 824 to the talus 222.	365	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Next a surgeon may operate the example talus resection guide 824 by inserting 1614 a cutting tool such as a rectangular oscillating blade or a burr attached to a manual, mechanical, pneumatic, or electric driver into a resection feature to cut the talus 222 for an osteotomy. If the surgeon has not yet formed a first osteotomy using the tibial resection guide 822, the surgeon may also insert 1608 a cutting tool (possibly the same cutting tool as used for the tibial resection) into a resection feature of the tibial resection guide 822 to form a first osteotomy.	366	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	In one embodiment, FIG. 17E illustrates a stage in which a tibial resection guide 822 and a talus resection guide 824 have been removed. Pins in the tibia 226 may be retained and pins in the talus 222 may be retained. A first osteotomy has been formed at the distal end of the tibia 226 and a second osteotomy has been formed at the proximal end of the talus 222. A resection interface that includes the two osteotomies can now be closed. Once closed, and/or the osteotomies are reduced, a surgeon can proceed with fixation across the first osteotomy and the second osteotomy to enable fusion for the tibia 226 to the talus 222. In one embodiment, a surgeon may deploy a positioning guide 1534 to assist with the reduction and/or to hold the reduction in a stable relationship while fixation is deployed.	367	Added by DJM Jan 2024	1/6/24, 10:01 PM
