View Edit Delete	PER-17	Referring to FIG. 13B, as indicated in the workflow pane 1306 with the highlight 1314, the workflow 1050 is on step #9. Steps #6-8 have been completed. The canvas 1304 illustrates an active model 1316 of a first metatarsal 208 with the base on the left side and the head on the right side of the canvas 1304. The view through the canvas 1304 is from a medial side of the active model 1316.	328	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	In step 6, a user 1002 has selected a vertex 1320 for defining a bone model longitudinal axis 1322 through the active model 1316 of a first metatarsal 208. In the illustrated embodiment, selection of a vertex 1320 is an initial step in defining a bone model longitudinal axis 1322. Next, in step 7, the system 1000 may define a plane 1324 through the selected vertex 1320 and perpendicular to the view through the canvas 1304. Next, the system 1000 may define a bone model longitudinal axis 1322 as a horizontal line from left to right that intersects the plane 1324 perpendicular to the view at the selected vertex 1320. The horizontal line is then designated, for example by the system 1000, as the bone model longitudinal axis 1322. In the illustrated example, the user 1002 has cooperated with the system 1000 to determine the bone model longitudinal axis 1322.	329	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	As illustrated, the bone model longitudinal axis 1322 is centered vertically within the active model 1316 of the first metatarsal 208. Thus, the bone model longitudinal axis 1322 is centered within the sagittal plane 262. In addition, the bone model longitudinal axis 1322 should be centered within the transverse plane 266 and the frontal plane 264. Consequently, selection of the vertex 1320, step 6 by the user 1002, is an important step in defining the bone model longitudinal axis 1322. In fact, in embodiments that rely on the proper and accurate defining of the bone model longitudinal axis 1322, step 6 may be considered a key step. Said another way, the bone model longitudinal axis 1322 may serve as a reference feature. This reference feature may be used by one or more other aspects in the bone model 404 and/or a patient-specific device model 1072. Those of skill in the art will appreciate that if the bone model longitudinal axis 1322 is not accurate other measurements and/or steps in the workflow 1050 may also be inaccurate.	330	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	Advantageously, embodiments of the present disclosure enable key steps to be designated to a skilled operator, user 1002. Alternatively, the user 1002 may perform key steps together with the aid of the system 1000. The performance of key steps by a user 1002 can provide valuable safeguards and checks on the use of automation and/or advanced computer analysis system, expert systems, machine learning, and/or automated/artificial intelligence (e.g., ANN, GAN, or the like).	331	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	Note that in one embodiment, step 8 is a step performed by the user 1002. The user 1002 is to adjust and/or check the position of the bone model longitudinal axis 1322 to confirm that the bone model longitudinal axis 1322 is centered within the active model 1316 of the first metatarsal 208 in the sagittal plane 262, transverse plane 266, and frontal plane 264. If the user 1002 determines that the bone model longitudinal axis 1322 is not correctly centered, the user 1002 may adjust the position of the bone model longitudinal axis 1322 within an appropriate axis. Alternatively, or in addition, the user 1002 may use tools of the user interface 1300 to adjust the position of the bone model longitudinal axis 1322. Thus, in this example, the workflow 1050 includes one or more steps of determining a longitudinal axis for an active model 1316 of a bone model 404.	332	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	In certain embodiments, steps such as step 6 and/or steps 6-8 may be optimized by way of automation and/or advanced computer analysis system, expert systems, machine learning, and/or automated/artificial intelligence (e.g., ANN, GAN, or the like). For example, the patient-specific device design apparatus 450 may include executable computer code configured to determine a longitudinal axis for an active model 1316 of the bone model 404. In such embodiments, the accuracy of the automation and/or advanced computer analysis system and/or artificial intelligence may be such that further adjustment by a user may not be necessary. Alternatively, or in addition, a check of the work of the system 1000 by a user 1002 may still be included in the workflow 1050 to ensure that mistakes are not made and/or are not missed. Thus, even key steps in certain embodiments may use automation, advanced computer analysis system, expert systems, machine learning, and/or automated/artificial intelligence (e.g., ANN, GAN, or the like).	333	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	FIG. 13B illustrates that in step 9, a user may define and/or adjust an offset, a width measured from a proximal end 1326 of the active model 1316 to the distal end 1328, for an osteotomy of the proximal end 1326. Such a step can be done by the system 1000 with a default offset and then subsequently adjusted by a user 1002. Alternatively, step 9 can be done solely by the user 1002 with reference to a set of work instructions 1040 and/or a prescription 1100 to make the offset match the request of a surgeon. Once step 9 is completed, a cut plane for an osteotomy is defined for the active model 1316 of the first metatarsal 208.	334	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	FIG. 13C illustrates an exemplary user interface 1300 for one step, one stage, of a workflow 1050 for generating a patient-specific device 1090, according to one embodiment. At this stage, the workflow 1050 has progressed to step 19.	335	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	Note that in step 17, a user 1002 has positioned the active model 1316 of the first metatarsal 208 relative to an active model 1316 of the medial cuneiform 202. For the illustrated embodiment, the distal end of the active model 1316 of the medial cuneiform 202 will receive an osteotomy and the proximal end 1326 of the active model 1316 of the first metatarsal 208 will receive an osteotomy. The user 1002 has repositioned the active model 1316 of the first metatarsal 208 relative to an active model 1316 of the medial cuneiform 202 to provide a correction, a corrected positioning/orientation. In one embodiment, the user 1002 may use a context model 1318 of the second metatarsal 210 as a reference feature and may reposition the active model 1316 of the first metatarsal 208 until the active model 1316 of the first metatarsal 208 is parallel and/or substantially parallel to the context model 1318 of the second metatarsal 210. Note that the user 1002 may confirm the corrected positioning in the sagittal plane 262, frontal plane 264, and transverse plane 266. Step 17 may also be a key step and a user 1002 may complete this step independently and/or with the assistance of the system 1000.	336	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	In step 18, the system 1000 may display/illustrate an active model 1316 of a first proximal phalange 230 and an active model 1316 of a first distal phalange 240 in the same position as these bones where when the medical imaging 1030 was generated. In certain embodiments, the bone model of the first proximal phalange 230 and the bone model of the first distal phalange 240 may be active models 1316 because a surgeon may want to do other procedures on one or more of these bones, such as an Akin procedure.	337	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	In the illustrated embodiment, the model 1312 is a bone model 404 that includes a set of active models 1316. The set of active models 1316 includes a first metatarsal model, a medial cuneiform model, a first proximal phalange, and a first distal phalange. Those of skill in the art will appreciate that models of bones to be used in a procedure should be in the set of active models 1316 so that an osteotomy and/or interaction with implants and/or hardware can be presented to an operator and/or a surgeon.	338	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	In certain embodiments, the number of models that are active models 1316 may be kept to a minimum to preserve computing resources. In the illustrated embodiment, the bone models in the canvas 1304 that are not in the set of active models 1316 may be members of the set of context models 1318. Those of skill in the art will appreciate that models for bones that are not active models 1316 provides needed context for the surgical procedure but these models need not be active model 1316 where they are used for context rather than being actively used in a surgical procedure. With up to 26 bones in a human patient’s foot, those of skill in the art will appreciate the benefits of certain bone models being active models 1316 and others context models 1318.	339	Added by DJM Jan 2024	1/6/24, 10:05 PM
View Edit Delete	PER-17	In certain embodiments, the set of active models 1316 may also include any of the bones of a patient’s foot. For example, a bone of the second metatarsal 210 and/or a model of the third metatarsal 212 may also be in the set of active models 1316 depending on the set of work instructions 1040. However, the number of bone models that are active models 1316 may be kept to a minimum to conserve computing resources.	340	Added by DJM Jan 2024	1/6/24, 10:05 PM
