View Edit Delete	PER-32	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, 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 guide 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 guide 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.	72	Added by DJM Jan 2024	1/6/24, 9:48 PM

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 the a 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 guide 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.	73	Added by DJM Jan 2024	1/6/24, 9:48 PM
View Edit Delete	PER-32	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, and/or tendon condition of a patient.	74	Added by DJM Jan 2024	1/6/24, 9:48 PM
View Edit Delete	PER-32	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 entail capturing a scan of only the first cuneiform and first metatarsal, or may entail capture of additional anatomic information, such as the entire foot. Additionally or alternatively, the step 122 may entail 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.	75	Added by DJM Jan 2024	1/6/24, 9:48 PM
View Edit Delete	PER-32	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.	76	Added by DJM Jan 2024	1/6/24, 9:48 PM
View Edit Delete	PER-32	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.	77	Added by DJM Jan 2024	1/6/24, 9:48 PM
View Edit Delete	PER-32	In a step 128, the model(s) may be used to manufacture patient-specific instrumentation and/or instruments. This may include manufacturing the guide 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.	78	Added by DJM Jan 2024	1/6/24, 9:48 PM
View Edit Delete	PER-32	In a step 130, the manufactured guide may be used in surgery to facilitate treatment of the condition. Specifically, the bone engagement surface of the guide may be placed against the corresponding contours of the bone. The guide 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 guide may then be removed, and the remaining steps of a surgical procedure performed.	79	Added by DJM Jan 2024	1/6/24, 9:48 PM
View Edit Delete	PER-32	The method 100 and the method 120 are merely exemplary. Those of skill in the art will recognize that various steps of the method 100 and the method 120 may be reordered, omitted, and/or supplemented with additional steps not specifically shown or described herein.	80	Added by DJM Jan 2024	1/6/24, 9:48 PM
