Delete 		PER-24 FIGS. 10E, 10F, 11D, 11E, and 11F illustrate a bone engagement surface 832 of an example talus resection guide 824. The bone engagement surface 832 facilitates registration of the talus resection guide 824 to the talus 222. The position of the talus resection guide 824 on a proximal end of the talus 222 may be determined by a surgeon preoperatively. FIGS 10E and 10J illustrate examples of a structure of a talus resection guide 824 that can serve as a landmark registration feature 834 and/or a bone engagement surface 832. The landmark registration feature 834 may form an indentation or pocket within a side wall of the talus resection guide 824. Whether or not a talus resection guide 824 includes a pocket shaped landmark registration feature 834 can depend on the anatomy of the patient and the desired position and orientation of the talus resection guide 824 as overseen by the surgeon. 270 Added by DJM Jan 2024 1/6/24, 10:01 PM

Delete 		PER-24 FIGS. 12A illustrates a stage of performing a surgical osteotomy procedure (e.g., tibia and/or talus osteotomy and/or ankle fusion) using the osteotomy system 800, according to one embodiment. The exemplary ankle fusion osteotomy system 800 can be used to perform osteotomies for a surgical procedure that includes one or more of a fusion of a joint (e.g., arthrodesis), joint replacement, such as a total ankle replacement, and/or correction of a deformity. A surgeon may elect to approach the osteotomies on the anterior side of the foot. FIG. 12A illustrates a left foot and shows a lateral perspective view and an anterior-posterior axis 888. FIG. 12A illustrates two resection guides 820 (e.g., tibial resection guide 822 and talus resection guide 824) one secured to the talus 222 and one secured to the tibia 226 by way of one or more bone attachment features 828 which may be implemented, at least in part, using fasteners 810 and/or one or more holes or openings in the tibial resection guide 822 and talus resection guide 824. 276 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 FIG. 12B illustrates a close up anterior view of the talus resection guide 824 and tibial resection guide 822 positioned on the talus 222 and the tibia 226 of the left foot. Other foot bones are not shown for clarity. The talus resection guide 824 and/or tibial resection guide 822 may each include one or more resection features 826. The resection features 826 may serve similar, or the same, purposes as the resection features 722 and/or other resection features described herein. The resection features 826 guide a cutting tool in performing an osteotomy. Advantageously, as with other embodiments described herein, the number, size, configuration, length, width, position, and/or angle in one or more planes of the resection features 826 can be defined for a particular patient or for a group of patients and can be included in the tibial resection guide 822 and/or resection guard 870 provided for a surgical procedure. 277 Added by DJM Jan 2024 1/6/24, 10:01 PM

Delete 		PER-24 The bone attachment features 828 secure the resection guide 820 to the bone for performing an osteotomy. Advantageously, as with other embodiments described herein, the number, size, configuration, length, width, position, and/or angle in one or more planes of the bone attachment features 828 can be defined for a particular patient or group of patients. In certain embodiments, one or more of the bone attachment features 828 (e.g., bone attachment features 828a, b, c, d) may be configured to enter the bone at predefined angles such that the pins, K-wires, or fasteners used as part of the bone attachment features 828 diverge, converge, or are parallel to each other as they extend into the bone. 278 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 FIG. 12B illustrates that the bone attachment features 828 of the tibial resection guide 822 may be angled such that the fasteners diverge as they extend into the tibia 226. This divergence can be advantageous since it can provide a stable engagement between the resection guide 820 and the bone. Similarly, converging bone attachment features 828 as they extend into the bone can also provide stable engagement of the bone. Alternatively, or in addition, divergence and/or convergence of one or more bone attachment features 828 can minimize the number of one or more bone attachment features 828 used for a surgical procedure. This can save time and materials. In the illustrated embodiment, bone attachment feature 828a may be angled medially and bone attachment feature 828b may be angled laterally. In another embodiment, bone attachment feature 828a may be angled to enter the bone perpendicular to surface and bone attachment feature 828b may be angled to converge with bone attachment feature 828a (either outside or within the bone). Advantageously, a surgeon can request certain configurations and/or trajectories for the bone attachment features 828 (e.g., by way of the user instructions 604). 279 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 Those of skill in the art will appreciate that the talus resection guide 824 and/or the tibial resection guide 822 may include more or fewer bone attachment features 828 than those included in the illustrated embodiments. For example, in one embodiment, the talus resection guide 824 may include one or more additional bone attachment features 828 near a medial side 856 and/or near resection feature 826b. In certain embodiments, the number of bone attachment features 828 may be determined at least in part by user instructions 604. 280 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 In the illustrated embodiment, the talus resection guide 824 includes two resection features 826 (resection feature 826a, resection feature 826b). Those of skill in the art will appreciate that a single resection feature 826 can be used instead of two or more resection features 826. In one embodiment, the resection feature 826b can assist a surgeon in resecting hard and/or soft tissue on a medial side of the joint. Such resection can contribute to a successful surgical procedure. In one embodiment, such resection may create clearance on the talus 222 for the talus 222 to fit under a medial malleolus when fused to the tibia 226. In certain embodiments, a resection feature 826 can be included on the lateral side of the talus resection guide 824. Similarly, additional resection features 826 can be used on the tibial resection guide 822 as well. 281 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 The resection feature 826a may be used to make a primary resection of the talus 222. The resection feature 826b may be used to make a secondary, or additional resection, along a side of the talus 222 (e.g., a medial side of the talus 222). During the surgical procedure, a surgeon may resect within the resection feature 826b to remove medial parts of the talus 222 and/or parts of the medial malleolus (e.g., within a medial gutter between the tibia 226 and the talus 222) to facilitate a clean and accurate fit between the resected talus 222 and the resected tibia 226 during reduction and for the fusion. 282 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 In certain embodiments, the resection feature 826a can be angled in a cephalad/dorsal direction or a caudal/plantar direction within the transverse plane 266. Alternatively, or in addition, the resection feature 826a can be angled in a cephalad/dorsal direction or a caudal/plantar direction within the sagittal plane 262. Alternatively, or in addition, the resection feature 826a can be positioned to resect the talus 222 normal to the transverse plane 266. 283 Added by DJM Jan 2024 1/6/24, 10:01 PM
View Edit
Delete 		PER-24 Advantageously, a surgeon (e.g., end user) and/or fabricator of the resection guides 820 can predefine desired angles, locations, and sizes for any, each, or all of the resection features 826 of the resection guides 820. For example, size, angle, orientation, trajectory, and location for any of the resection feature 826 can be determined by way of the user instructions 604. In this manner, a surgeon can resect the tibia 226 and/or talus 222 in such a way that positions the talus 222 fore, aft, medial, or lateral within the joint when fused to correct a deformity. 284 Added by DJM Jan 2024 1/6/24, 10:01 PM
