View Edit Delete	PER-8 PROV	In one embodiment, the CAD model generated and/or patient-specific instrumentation, implants, and/or plan for conducting an operative procedure, may be enhanced by the use of advanced computer analysis, machine learning, and/or automated/artificial intelligence. For example, these technologies may be used to revise a set of steps for a procedure such that a more desirable outcome is achieved.	36	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	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, 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 cutting 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 cutting guide and the patient-specific synthetic cadaver can be provided to a surgeon who can then rehearse an operation procedure in full before going into an operating room with the patient.	46	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	In certain embodiments, one or more of a method, apparatus, and/or system of the disclosed solution can be used for training a surgeon to perform a patient-specific procedure or technique. In one embodiment, the CAD model generated and/or patient-specific instrumentation, implants, and/or plan for conducting an operative procedure can be used to train a surgeon to perform a patient-specific procedure or technique.	45	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	As mentioned previously, the method 100 may be used to correct a wide variety of bone conditions. One example of the method 100 will be shown and described in connection with Figure 1B, for correction of a bunion deformity of the foot.	44	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	In addition to, or in the alternative to the step 108, the model(s) may be used to select from available sizes of implants and/or instruments and advise the surgeon accordingly. For example, where a range of cutting guides are available for a given procedure, analysis of the CAD data may facilitate pre-operative selection of the optimal cutting guide and/or optimal placement of the cutting guide on the bone. Similarly, if a range of implants may be used for a given procedure, analysis of the CAD data may facilitate pre-operative selection of the optimal implant(s). More particularly, properly-sized spacers, screws, bone plates, and/or other hardware may be pre-operatively selected.	41	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	As used herein, “additive manufacturing” refers to a manufacturing process in which materials are joined together in a process that repeatedly builds one layer on top of another to generate a three-dimensional structure or object. Additive manufacturing may also be referred to using different terms including: additive processes, additive fabrication, additive techniques, additive layer manufacturing, layer manufacturing, freeform fabrication, ASTM F2792 (American Society for Testing and Materials), and 3D printing. Additive manufacturing can build the three-dimensional structure or object using computer-controlled equipment that applies successive layers of the material(s) based on a three-dimensional model that may be defined using Computer Aided Design (CAD) software. Additive manufacturing can use a variety of materials including polymers, thermoplastics, metals, ceramics, biochemicals, and the like.	40	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	In a step 108, the model(s) may be used to manufacture patient-specific instrumentation and/or implants. This may be done via any known manufacturing method, including casting, forging, milling, additive manufacturing, and/or the like. Additive manufacturing may provide unique benefits, as the model may be directly used to manufacture the instrumentation and/or implants (without the need to generate molds, tool paths, and/or the like beforehand). Such instrumentation may optionally include a cutting guide with the bone apposition surface and one or more guide features as described above.	39	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	As used herein, a "guide" refers to a part, component, or structure designed, adapted, configured, or engineered to guide or direct one or more other parts, components, or structures. A guide may be part of, integrated with, connected to, attachable to, or coupled to, another structure. In one embodiment, a guide may include a modifier that identifies a particular function, location, orientation, operation, type, and/or a particular structure of the guide. Examples of such modifiers applied to a guide, include, but are not limited to, "pin guide" that guides or directs one or more pins, a "cutting guide" that guides or directs the making or one or more cuts, and the like. As used herein, "feature" refers to a distinctive attribute or aspect of something. (Search "feature" on google.com. Oxford Languages, 2021. Web. 20 Apr. 2021.) A feature may include a modifier that identifies a particular function or operation and/or a particular structure relating to the feature. Examples of such modifiers applied to a feature, include, but are not limited to, "attachment feature," "securing feature," "protruding feature," "engagement feature," "disengagement feature," and the like.	38	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	In a step 106, the CAD model and/or CT scan data may be used to model patient-specific instrumentation that can be used to correct the condition, as it exists in the patient’s anatomy. In some embodiments, any known CAD program may be used to view and/or manipulate the CAD model and/or CT scan, and generate one or more instruments that are matched specifically to the size and/or shape of the patient’s bone(s). In some embodiments, such instrumentation may include a cutting guide that is attachable to one or more bones, with one or more guide features that facilitate resection of the one or more bones pursuant to a procedure such as arthroplasty or arthrodesis. In some embodiments, performance of the step 106 may include modelling an instrument with a bone apposition surface that is shaped to match the contour of a surface of the bone, such that the bone apposition surface can lie directly on the corresponding contour.	37	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	securing bone attachment features to one or more of the first bone and the second bone using the one or more alignment features of the cutting guide;	150	Added by DJM 7 2021	7/2/21, 12:00 AM
