TMC-PAT-4 The position of the proximal resection feature 902 and/or distal resection feature 904 within the body 900, with relation to each other, the orientation of the proximal resection feature 902 and/or distal resection feature 904 between the proximal side 918 and the distal side 920, and/or the angle of the proximal resection feature 902 and/or distal resection feature 904 through the body 900 may be at least partially determined based on a bone model of a patient’s foot. The bone model may be of one bone or of a plurality of bones. The bone model may be defined based on medical imaging of the patient’s foot. In one embodiment, the first trajectory 928 may be at least partially determined based on the bone model. Similarly, the second trajectory 930 may be at least partially determined based on at least one of the bone model and the first trajectory 928. In this manner, at least in certain embodiments, the number, position, orientation, size, length, angle of incidence to the inferior side 916, and the like are or can be patient-specific. Of course, a surgeon can alter or adjust any of these aspects of the resection guide 820b to enable fabrication of a guide that meets the surgeon’s needs, preferences, and/or the needs of the patient and/or the surgical procedure. In one embodiment, the first trajectory 928 and/or the second trajectory 930 are patient-specific. 290 Added by DJM Jan 2024 1/3/24, 4:24 AM

TMC-PAT-4 In one example embodiment, a surgeon may submit a CT scan of a patient’s foot to an apparatus or system that implements the disclosed solution. Next, a manual or automated process may be used to generate a CAD model and for making the measurements and correction desired for the patient. In the automated process, an advanced computer analysis system, machine learning and automated/artificial intelligence may be used to generate a CAD model and/or one or more patient-specific instruments and/or operation plans. For example, a patient-specific instrument may be fabricated that is registered to the patient’s anatomy using a computer-aided machine (CAM) tool. In addition, a CAM tool may be used to fabricate a 3D structure representative of the patient’s anatomy, referred to herein as a patient-specific synthetic cadaver. (e.g., one or more bones of a patient’s foot). Next, the patient-specific instrument and the patient-specific synthetic cadaver can be provided to a surgeon who can then rehearse an operation procedure in part or in full before going into an operating room with the patient. 151 Added by DJM Jan 2024 1/3/24, 4:24 AM

TMC-PAT-4 In certain embodiments, the patient-specific instrument or instrument can be used to preposition and/or facilitate pre-drilling holes for a plate system for fixation purposes. Such plate systems may be optimally placed, per a CT scan, after a correction procedure for optimal fixation outcome. In another embodiment, the CAD model and/or automated process such as advanced computer analysis, machine learning and automated/artificial intelligence may be used to measure a depth of through a patient-specific resection guide for use with robotics apparatus and/or systems which would control the depth of each cut within the guide to protect vital structures below or adjacent to a bone being cut. In another embodiment, the CAD model and/or automated process such as advanced computer analysis, machine learning and automated/artificial intelligence may be used to define desired fastener (e.g. bone screw) length and/or trajectories through a patient-specific instrument and/or implant. The details for such lengths, trajectories, and components can be detailed in a report provided to the surgeon preparing to perform a procedure. 152 Added by DJM Jan 2024 1/3/24, 4:24 AM

TMC-PAT-4 FIG. 1B is a flowchart diagram depicting a method 120 for correcting or remediating a bone condition, according to one embodiment. The method 120 may be used to prepare for an orthopedic procedure which corrects or remediates a bone, muscle, deformity, and/or tendon condition of a patient. 153 Added by DJM Jan 2024 1/3/24, 4:24 AM

TMC-PAT-4 As shown, the method 120 may begin with a step 122 in which a CT scan (or another three-dimensional image) of the patient’s foot is obtained. The step 122 may include capturing a scan of select bones of a patient or may include capturing additional anatomic information, such as the entire foot. Additionally, or alternatively, the step 122 may include receipt of previously captured image data. Capture of the entire foot in the step 122 may facilitate proper alignment of the first metatarsal with the rest of the foot (for example, with the second metatarsal). Performance of the step 122 may result in generation of a three-dimensional model of the patient’s foot, or three-dimensional surface points that can be used to construct such a three-dimensional model. 154 Added by DJM Jan 2024 1/3/24, 4:24 AM

TMC-PAT-4 After the step 122 has been carried out, the method 120 may proceed to a step 124 in which a CAD model of the relevant portion of the patient’s anatomy is generated. The CAD model may optionally include the bones of the entire foot, like the CT scan obtained in the step 122. In alternative embodiments, the step 124 may be omitted in favor of direct utilization of the CT scan data, as described in connection with the step 104. 155 Added by DJM Jan 2024 1/3/24, 4:24 AM

TMC-PAT-4 In a step 126, the CAD model and/or CT scan data may be used to model patient-specific instrumentation that can be used to correct or remediate a bone condition. Such instrumentation may include a guide. In one example, the guide can seat or abut or contact a surface of a bone and including an opening that guides a trajectory for a fastener for a procedure. In some embodiments, performance of the step 126 may include modelling the guide with a bone engagement surface that is shaped to match contours of the surfaces of the bone, such that the bone engagement surface can lie directly on the corresponding contours of the bone. 156 Added by DJM Jan 2024 1/3/24, 4:24 AM

TMC-PAT-4 In a step 128, the model(s) may be used to manufacture patient-specific instrumentation and/or instruments. This may include manufacturing an instrument with the bone engagement surface and/or other features as described above. As in the step 108, the step 128 may additionally or alternatively involve provision of one or more instruments and/or implants from among a plurality of predetermined configurations or sizes. Further, the step 128 may additionally, or alternatively, involve provision of instructions for placement and/or anchorage of one or more instruments and/or instruments to carry out the procedure. 157 Added by DJM Jan 2024 1/3/24, 4:24 AM

TMC-PAT-4 In a step 130, the manufactured instrument may be used in surgery to facilitate treatment of the condition. In certain embodiments, a bone engagement surface of the instrument may be placed against the corresponding contours of the bone. The instrument may include an opening and/or trajectory guide to guide insertion of a trajectory guide such as a temporary fastener such as a K-wire. The instrument may then be removed, and the remaining steps of a surgical procedure performed. 158 Added by DJM Jan 2024 1/3/24, 4:24 AM
