View Edit Delete	PER-8 PROV	Referring to FIG. 12H, in certain embodiments, the cutting guide 1200 may include a detachable connector 1270 that couples an alignment feature 1260a, 1260b to the body 1210. The detachable connector 1270 may connect or couple the alignment feature 1260a to the body 1210 and/or the alignment feature 1260b to the body 1210. In one embodiment, the detachable connector 1270 may comprise a breakaway structure designed, engineered, and fabricated to securely connect an alignment feature 1260a, 1260b to the body 1210 for one part of a procedure and to readily separate or breakaway from the body 1210 when a breaker tool 1271 (See FIG. 14) is used to activate the breakaway function or feature.	128	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	In the embodiment of FIG. 12A, one alignment feature 1260a is in the lower right-hand side of the metatarsus apposition portion 1244 and the other alignment feature 1260b is on the left-hand side of the cuneiform apposition portion 1242. The two alignment features 1260a and 1260b may be separate features, or certain features such as one or more attachment features may serve a dual purpose as both an attachment feature and as an alignment feature. For example, in the embodiment of FIG. 12A, alignment feature 1260b may use the same structure as the bone attachment features and may take the form of holes 1240 that extend from a bone apposition side 1230 to the outward-facing side 1232.	127	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	Returning to Figures 12A through 12H, the body 1210 may further have features that facilitate desired translation and orientation of the first metatarsus in order to fuse or join the first cuneiform and the first metatarsus to complete the procedure. For example, in the illustrated embodiment, the cutting guide 1200 may include two alignment features 1260a and 1260b.	126	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	FIG. 14 illustrates a 3D color perspective view of a first cuneiform 210 and first metatarsus 230 with one embodiment of a cutting guide 1400 secured to the two bones. The cutting guide 1400 includes pins 1280a-f in the holes 1240 of bone attachment features and the holes 1278 of the alignment features 1260, such as alignment feature 1260a.	134	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	In the embodiment of Figures 12A through 12F, the guide features may guide a reciprocating planar blade, such as that of a surgical bone saw, that forms planar cuts in the first cuneiform and the first metatarsus. Thus, the guide features may take the form of a first slot 1250 and a second slot 1252, which may be positioned toward the center of the body 1210. Thus, upon proper positioning of the cutting guide 1200, the first slot 1250 may be positioned over the first cuneiform to facilitate resection of the first cuneiform, while the second slot 1252 may be positioned over the first metatarsus to facilitate resection of the first metatarsus.	124	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	The body 1210 may further have guide features that guide a cutter to resect the first cuneiform and the first metatarsus in the manner needed to make the desired correction. For example, the guide features may be used to guide a planar cutting blade, an arcuate cutting blade, a drill or mill, a burr, and/or the like.	123	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	The bone apposition side 1230 may be custom contoured to match the shapes of the first cuneiform and/or the first metatarsus. As embodied in Figures 12A through 12F, the bone apposition side 1230 may have a cuneiform apposition portion 1242 shaped to lie against the surface of the first cuneiform, and a metatarsus apposition portion 1244 shaped to lie against the surface of the first metatarsus. As shown, the cuneiform apposition portion 1242 may be contoured to match the contour of the surface of the first cuneiform on which it is to rest, and the metatarsus apposition portion 1244 may similarly be contoured to match the contour of the surface of the first metatarsus on which it is to rest. Thus, the body 1210 may have only one stable position and orientation relative to the first cuneiform and the first metatarsus.	122	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	Further, the body 1210 may have one or more bone attachment features that facilitate attachment of the body 1210 to the first cuneiform and/or the first metatarsus. Such bone attachment features may comprise any of a wide variety of holes, spikes, fastening devices, and/or the like. As embodied in Figures 12A through 12H, the bone attachment features may take the form of holes 1240 that extend from a bone apposition side 1230 to the outward-facing side 1232. The holes 1240 may be shaped to accommodate pins, K-wires, and/or other elongated bone fixation elements that can be anchored in the first cuneiform and/or the first metatarsus to keep the cutting guide 1200 in place.	121	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	As shown, the cutting guide 1200 may have a body 1210 with a monolithic construction and the general shape of a rectangular prism. The body 1210 may reside on the dorsal surfaces of the first cuneiform and the first metatarsus to provide proper alignment of the body 1210 with the metatarsocuneiform joint.	120	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	The cutting guide 1200 may be designed to facilitate resection of a first cuneiform and a first metatarsus with planar cuts at the proper angles to provide dual-plane correction of the orientation of the first metatarsus, thereby providing correction in a lateral direction and in a plantar direction or a dorsal direction.	119	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	Figures 12A, 12B, 12C, 12D, 12E, 12F, 12G, and 12H are top perspective, top, bottom, front elevation, rear elevation, right, left, and alternative top perspective, respectively, of a patient-specific cutting guide, or cutting guide 1200, according to one alternative embodiment.	118	Added by DJM 7 2021	7/2/21, 12:00 AM
View Edit Delete	PER-8 PROV	Referring to FIG. 16, in certain embodiments, a parallel distractor 1600 such as the exemplary parallel distractor 1600 having holes 1602 illustrated in FIG. 16 can be used to distract the first metatarsus 230 relative to the first cuneiform 210. The parallel distractor 1600 may also include a cross joint guide 1604. The user may slide holes 1602a,b over pins 1280a,b and holes 1602c,d (not visible, obscured by holes 1606a,b which are aligned with holes 1602c,d) over pins 1280e,f.	142	Added by DJM 7 2021	7/2/21, 12:00 AM

View Edit Delete	PER-8 PROV	The cross joint guide 1604 may serve as a guide for cross joint fasteners or other kinds of implants or fixation devices that can be installed across a joint between the first cuneiform 210 and the first metatarsus 230. In one embodiment, the cross joint guide 1604 may include one or more bone attachment features that may take the form of holes 1608 that extend from one side of the cross joint guide 1604 to the other side. The holes 1608 may be used to connect a holding across the joint between the first cuneiform 210 and the first metatarsus 230 after compression.	143	Added by DJM 7 2021	7/2/21, 12:00 AM
