Delete 		PER-24 One example of this variation in a depth of the body can be seen in the example resection guide 1820 (i.e., second resection guide 1824) in FIG. 20C. FIG. 20C illustrates a left side view (posterior side 2006, because the second resection guide 1824 is configured for use on a lateral side of a patient’s ankle) of the second resection guide 1824. Note that the body 2002 is shorter near the superior side 2012 than near the inferior side 2014. In other words, the posterior side 2006 is wider at or near the inferior end than at or near the superior end. This difference in width can be used to set a trajectory for the second resection feature 1866 relative to one or more bones. 403 Added by DJM Jan 2024 1/6/24, 10:01 PM

Delete 		PER-24 The sights 1894 serve to assist a surgeon in reviewing, confirming, and/or validating a position of the second resection guide 1824 relative to other anatomical structures of the patient (e.g., bones). In one embodiment, sights 1894 are used during a surgical procedure and can be used together with medical imaging to check position, alignment, trajectory, or the like. In one embodiment, a surgeon may provisionally position the second resection guide 1824 and then use flouroscopy to visually check or confirm a position of the second resection guide 1824 relative to another bone or other bones of the patient. In certain embodiments, the flouroscopy machine (e.g., C-arm) can include reference features that key off of certain markers or anatomical features of the patient to ensure that the flouroscopy image is the view desired for the surgeon. A surgeon may use the flouroscopy machine and locate a sight 1894 to determine whether or not the second resection guide 1824 is in a desired position. In one embodiment, the flouroscopy machine may include a scope or view finder or corresponding sight (e.g., cross hairs) that a surgeon can align with the sight 1894 to do a visual check and/or confirmation of the position of the second resection guide 1824. After this visual check, a surgeon may secure the second resection guide 1824 to one or more bones of the patient (i.e., deploy pins in bone attachment features 1828). 405 Added by DJM Jan 2024 1/6/24, 10:01 PM

Delete 		PER-24 FIGs. 20B, 20G, and 20H illustrate an example embodiment of the second resection guide 1824 illustrated in FIG. 20. The second resection guide 1824 includes a particular type of bone engagement feature 1830’. In the illustrated embodiment, the bone engagement feature 1830’ includes an insert 2016 and a bone engagement surface 2018. 408 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 The insert 2016 is a structure that is configured to extend into a space such as a curved osteotomy. In another embodiment, an insert 2016 is configured to extend into a space between bones of a joint. Advantageously, the insert 2016 assists a surgeon in confirming that the second resection guide 1824 is in a desired position, prior to securing the second resection guide 1824 to one or more bones and/or performing an osteotomy. 409 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 In the illustrated embodiment, the second resection guide 1824 is configured to be used for a second osteotomy after a first osteotomy is performed (e.g., using the first resection guide 1822). The second resection guide 1824 uses resected bone surfaces from the first osteotomy to position and/or orient the second resection guide 1824. Consequently, the bone engagement surface 2018 of the bone engagement feature 1830’ includes at least one surface configured to engage with one or more surfaces of a first osteotomy. In one embodiment, the bone engagement surface 2018 is configured to engage with both sides of a curved osteotomy. As discussed in more detail herein, a surgeon may use a first resection guide 1822 to form a first osteotomy, a curved osteotomy, that cuts into an end of one bone (e.g., a talus 222), an end of two bones (e.g., a talus 222 and a tibia 226), into a portion of a single bone (e.g., a talus 222 or tibia 226). 410 Added by DJM Jan 2024 1/6/24, 10:01 PM

Delete 		PER-24 Where the curved osteotomy resects ends of two bones of a joint, the curved osteotomy has a superior surface/side (resected surface of one bone) and an inferior surface/side (resected surface of another bone). In certain embodiments, the bone engagement surface 2018 is configured to engage with both sides of the curved osteotomy. As shown in the example of FIG. 21D, these side surfaces of the osteotomy can be generally smooth and curved or rounded. Accordingly, FIG. 20H illustrates that the bone engagement surface 2018, in one embodiment, includes a superior bone engagement surface 2020 and an inferior bone engagement surface 2022. 411 Added by DJM Jan 2024 1/6/24, 10:01 PM

Delete 		PER-24 In certain embodiments, a resection guide 1820 (e.g., first resection guide 1822 and/or second resection guide 1824) can include a plurality of bone engagement surfaces that are either independent or part of a bone engagement feature 1830. In one embodiment, such as the example of FIGs. 20B and 20H, the resection guide 1820 can include a first bone engagement surface (e.g., superior bone engagement surface 2020) on one side and a second bone engagement surface (e.g., inferior bone engagement surface 2022) on another side. The two sides that include bone engagement surfaces may be opposite sides as with the superior bone engagement surface 2020 and the inferior bone engagement surface 2022. Alternatively, or in addition, the two sides that include bone engagement surfaces may be adjacent sides such as superior bone engagement surface 2020 on a bone engagement feature 1830’ of an insert 2016 and a bone engagement surface 1832 on a medial side 2008 of a body 2002. 412 Added by DJM Jan 2024 1/6/24, 10:01 PM

Delete 		PER-24 Advantageously, the bone engagement feature 1830’ with its insert 2016 can be modeled, designed, and/or fabricated based on at least a portion of a bone model of one or more bones of a patient. In particular, the bone engagement feature 1830’ can be modeled in relation to bone(s) of a patient after formation of a first osteotomy (e.g., a curved osteotomy). Thus, new space or openings formed by the first osteotomy can be used as reference features to position and/or register the second resection guide 1824 using the bone engagement feature 1830’. 413 Added by DJM Jan 2024 1/6/24, 10:01 PM

Delete 		PER-24 Pins of four bone attachment features 828 (e.g., one or more tibial bone attachment features and one or more talus bone attachment features) have also been deployed to secure the first resection guide 1822 to the tibia 226 and the talus 222. Note that the first resection guide 1822 includes an alignment guide 1874 with a shaft 1878 inserted. A surgeon can now visually check manually, and/or with flouroscopy, a position of the first resection guide 1822 in relation to a mechanical axis 880 of the tibia 226. A surgeon can now form a curved osteotomy in a sagittal plane 262 using the first resection feature 1864 and a cutting tool such as a burr. 417 Added by DJM Jan 2024 1/6/24, 10:01 PM

Delete 		PER-24 FIG. 21B illustrates the ankle joint after formation of a curved osteotomy and removal of the first resection guide 1822. In one embodiment, certain pins for bone attachment features 1828 such as those for the tibia 226 may remain in the bone. FIG. 21B illustrates that the curved osteotomy 2100 has been formed on or near a superior surface of the talus 222. In certain embodiments, this curved osteotomy 2100 can be used for or by other instruments during the surgical procedure. 418 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 In one embodiment, FIG. 21C illustrates a stage in which a second resection guide 1824 is positioned on a lateral side of the ankle. The second resection guide 1824 can be secured using one or more common pins that were used for the first resection guide 1822 and/or new pins may be deployed to secure the second resection guide 1824. In one embodiment, pins for bone attachment features 1828 in the tibia may be deployed using the bone attachment features 1828 at an angle that ensures that the second resection guide 1824 is securely coupled to the bone(s). In the illustrated embodiment, the second resection guide 1824 is positioned to resect a portion of an end of the tibia 226 in preparation for an ankle fusion. Next, a surgeon may form a second osteotomy, such as an angled curved osteotomy 2102. The angled curved osteotomy 2102 formed in the bone(s) may not be perpendicular to a mechanical axis 880 of the tibia 226. 419 Added by DJM Jan 2024 1/6/24, 10:01 PM
