View Edit Delete	PER-10	The method begins and the surgeon positions 3102 a patient specific cut guide across of joint of two bones of a patient. Next, the surgeon may secure 3104 the patient specific cut guide to the bones of the joint using pins (e.g., K-wires). Next, the surgeon may resect 3106 the articular surface of both bones of the joint. Next, the surgeon may remove 3108 the patient specific cut guide while leaving one or more pins in place on the bones. Pins left in place may include pins that are part of the proximal bone attachment feature 2252 and/or the distal bone attachment feature 2254. Next, the surgeon may de-rotate 3110 one or more bones of the joint. Next, the surgeon may connect 3112 an active compression instrument to pins on each bone of the joint. Next, the surgeon may compress 3114 the two bones of the joint together. Next, the surgeon may deploy 3116 fasteners across the joint. The fasteners may be temporary fasteners such as K-wires or bone screws or permanent fasteners such as a bone plate and bone screws.	314	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	FIG. 31 is a flow chart diagram of one example method 3100 for using a patient specific cutting guide according to one embodiment to mitigate a condition present in a patient. Before the method 3100 begins a surgeon may obtain a patient specific cut guide and/or one or more other instruments that may be patient specific or may be configured for use with most patients.	313	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	In the illustrated embodiment, of FIGS 30A, 30B, an inferior side, also referred to as the bone engagement surface of the preliminary cutting guide model 3000 has a squared and boxy configuration because the inferior side for the preliminary cutting guide model 3000 has not yet been defined. FIG. 30C illustrates an inferior side 3022, or bone engagement surface 3024 that has been defined to match the contour of bones of the patient based on patient imaging data. The modified preliminary cutting guide model 3000 of FIG. 30C is ready to be manufactured, for example, using additive manufacturing.	312	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Accordingly, referring to FIG. 30B, a second guide feature 3070 in the form of a second slot may be defined in the preliminary cutting guide model 3000 and configured to guide formation of a second cut surface of a second bone of the patient corresponding to the second modeled bone. The first guide feature 3060 and second guide feature 3070 are positioned in the preliminary cutting guide model 3000 such that fixing the first cut surface of the first bone to the second cut surface of the second bone mitigates the condition. Note that the preliminary cutting guide model 3000 includes both the first guide feature 3060 and the second guide feature 3070. In the illustrated embodiment, the second guide feature 3070 is oriented and positioned for formation of the second cut surface. In addition, a second hole 3050 is defined in the proximal arm 3030. The second hole 3050 aligns with a first hole 3050 of the proximal alignment feature 3080 in addition the holes of the proximal alignment feature 3080 are perpendicular to the second guide feature 3070.	311	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Next, as part of accessing 2910 a bone model, the bone model of the first modeled bone may be modified to include the first cut surface and the second modeled bone may be modified to include the second cut surface. In addition, one or more guide members of the preliminary cutting guide model 3000 are configured and positioned to enable a surgeon to form the first cut surface and the second cut surface.	310	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Next, as part of accessing 2910 a bone model, a first angle for a second cut surface of the second modeled bone may be defined. The first angle may be measured relative to the first cut surface and may extend inferiorly away from the first cut surface. FIG. 19D illustrates one example of the first angle by way of angle A. Next, a second angle for the second cut surface of the second modeled bone may be defined. The second angle may be measured relative to the first cut surface and configured to mitigate the condition. FIG. 19H illustrates one example of the first angle by way of angle B.	309	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Referring to FIGS. 19H and 20, in one embodiment, the body 1910, or one or more arms, may include one or more bone attachment features that facilitate attachment of the body 1910 to the first cuneiform 210 and/or first metatarsal 230. Such bone attachment features may include any of a wide variety of fasteners including, but not limited to, holes, spikes, fastening devices, and/or the like.	222	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	In alternative embodiments, a guide feature may be designed to guide a different type of cutter, such as a drill, mill, or side-cutting burr. In such embodiments, the guide feature may not be a slot, but may instead be a translatable or rotatable cutter retainer that guides translation and/or rotation of the cutter relative to the bone. In certain embodiments, two or more guide features may be replaced by a single guide feature sized to permit a surgeon to resect both a first cuneiform and a first metatarsal using a single cutting guide 1900.	210	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	In one embodiment, a first guide feature is configured to define a first cut surface that can be formed by resecting a first bone. A second guide feature is configured to define a second cut surface that can be formed by resecting a second bone. In such an embodiment, one or the other or both of the first cut surface and the second cut surface can be oriented according to one or more angles relative to landmarks on the bones or other anatomical structures.	211	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Alternatively, or in addition, in certain embodiments, one or both of, the first guide feature and second guide feature may be positioned on, or in, the body 1910 and/or have an orientation based on patient imaging data. The patient imaging data can be used to position and orient one, or both, of the first guide feature and second guide feature such that formation of one, or both, of the first cut surface and the second cut surface and fixation of the two cut surfaces against each other mitigates a condition of the patient. For example, as described in the present disclosure, patient imaging data can be used to generate bone models of bones of the patient. The bone models can be used to determine and/or define contours for a bone engagement surface 1924, a position for a first slot 1960, an orientation for a first slot 1960, a position for a second slot 1970, an orientation for a second slot 1970, as well as other features and attributes of one or more patient specific instruments that can be used in a procedure.	212	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	"Cut surface" refers to a surface of an object that is created or formed by the removal of one or more parts of the object that includes the original surface. Cut surfaces can be created using a variety of methods, tools, or apparatuses and may be formed using a variety of removal actions, including, but not limited to, fenestrating, drilling, abrading, cutting, sawing, chiseling, digging, scrapping, and the like. Tools and/or methods used for forming a cut surface can include manual, mechanical, motorized, hydraulic, automated, robotic, and the like. In certain embodiments, the cut surface(s) are planar.	213	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	"Orientation" refers to a direction, angle, position, condition, state, or configuration of a first object, component, part, apparatus, system, or assembly relative to another object, component, part, apparatus, system, assembly, reference point, reference axis, or reference plane.	214	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	FIG. 20 illustrates one embodiment of the cutting guide 1900 secured to a first metatarsal 230 and a first cuneiform 210. In the illustrated embodiment, the first guide feature may take the form of the first slot 1960 and the second guide feature may take the form of the second slot 1970. Referring now to FIGS. 20 and 19D, the position and/or angles (e.g., orientation) of one or both of the guide features based on patient imaging data is illustrated. In the illustrated embodiment, the first slot 1960 is positioned between the distal side 1914 and the second slot 1970. The first slot 1960 is oriented based on a desired angle for mitigating the condition of the patient. In one example, the first slot 1960 is angled perpendicular to a longitudinal axis of the first metatarsal 230. This orientation of the first slot 1960 enables the first cut surface to extend from the body 1910 toward the bone to form a cut surface that is also perpendicular to the longitudinal axis 1976 of one of the bones of a joint. "Longitudinal axis" refers to an axis of a structure, device, object, apparatus, or part thereof that extends from one end of a longest dimension to an opposite end. Typically, a longitudinal axis passes through a center of the structure, device, object, apparatus, or part thereof along the longitudinal axis. The center point used for the longitudinal axis may be a geometric center point and/or a mass center point. In the illustrated embodiment, the longitudinal axis 1976 is the longitudinal axis of the first metatarsal 230.	215	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	In the illustrated embodiment, the second slot 1970 is positioned between the proximal side 1912 and the first slot 1960. In addition in the illustrated embodiment, the second slot 1970 is oriented based on a desired angle for mitigating the condition of the patient. In the illustrated embodiment, the orientation of the second slot 1970 can be described in reference to a first angle A and a second angle B. FIG. 19D illustrates first angle A. In one embodiment, a second cut surface formed by resection using second slot 1970 extends inferiorly away from a first cut surface formed by resection using first slot 1960. Described another way, angle A is an angle between a first plane 1978 that includes the first slot 1960 and a first cut surface formed by resection using first slot 1960 and a second plane that includes the second slot 1970 and a second cut surface formed by resection using second slot 1970, the second plane extending from the first plane toward the proximal side 1912 of the body 1910. In certain embodiments, angle A can range between about 4 degrees to about 18 degrees. In certain embodiments, angle A may start at 0 degrees and then increase to a positive number of degrees as illustrated or decrease to a negative number of degrees depending on how a surgeon may prescribe adjustments for a correction.	216	Added by DJM 2 2022	2/25/22, 12:00 AM
