View Edit Delete	PER-10	FIG. 13 illustrates that in one embodiment, the holes 1240 of each bone attachment feature can be parallel to each other such that pins 1280 in the holes 1240 are parallel to each other. Red line A illustrates that the holes 1240a, 1240b are aligned perpendicular to a resection cut that has been made on the first cuneiform 210 through slot 1350. Pins 1280 in holes 1240a,b may be referred to as cuneiform pins and these parallel cuneiform pins form a line (red line A) perpendicular to a cut plane in the first cuneiform 210. Red line B illustrates that the holes and corresponding parallel pins 1281 (which may be referred to as metatarsal pins) may form a line perpendicular to a cut plane in the first metatarsal 230. The metatarsal pins 1281 are aligned perpendicular to a resection cut (also referred to as a MET cut) that has been made on the first metatarsal 230 through slot 1352.	154	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Like the implant 1060, the bone plate 1070 may be made of any known biocompatible material, through the use of any manufacturing process known in the art. In some embodiments, the bone plate 1070 may also be fabricated specifically for the foot 200, enabling the bone plate 1070 to precisely maintain the desired level of correction. When made specifically for the foot 200 in combination with each other, the implant 1060 and the bone plate 1070 may provide a highly predictable, precise, and customizable level of correction of the flat foot deformity.	134	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	The cutting guide 1200 may be designed to facilitate resection of a first cuneiform and a first metatarsal with planar cuts at the proper angles to provide dual-plane correction of the orientation of the first metatarsal, thereby providing correction in a lateral direction and in a plantar direction or a dorsal direction.	140	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	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 metatarsal to provide proper alignment of the body 1210 with the metatarsocuneiform joint.	141	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	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 metatarsal. 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 facing side 1230 to the outward-facing side 1232 and/or one or more fixation devices. 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 metatarsal to keep the cutting guide 1200 in place.	142	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	The bone facing side 1230 may be custom contoured to match the shapes of the first cuneiform and/or the first metatarsal. As embodied in Figures 12A through 12F, the bone facing side 1230 may have a cuneiform apposition portion 1242 shaped to lie against the surface of the first cuneiform, and a metatarsal apposition portion 1244 shaped to lie against the surface of the first metatarsal. 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 metatarsal apposition portion 1244 may similarly be contoured to match the contour of the surface of the first metatarsal 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 metatarsal.	143	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	The body 1210 may further have guide features that guide a cutter to resect the first cuneiform and the first metatarsal 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.	144	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	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 metatarsal. 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 metatarsal to facilitate resection of the first metatarsal.	145	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	Returning to Figures 12A through 12H, the body 1210 may further have features that facilitate desired translation and orientation of the first metatarsal in order to fuse or join the first cuneiform and the first metatarsal to complete the procedure. For example, in the illustrated embodiment, the cutting guide 1200 may include two alignment features 1260a and 1260b.	147	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	In the embodiment of FIG. 12A, one alignment feature 1260a is in the lower right-hand side of the body 1210, the distal side of the body, and the other alignment feature 1260b is on a proximal side of the body 1210. 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 facing side 1230 to the outward-facing side 1232 and/or one or more fixation devices.	148	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	In one embodiment, the alignment feature 1260, such as alignment feature 1260a, can include one or more bone attachment features that may take the form of holes 1278 that extend from a bone facing side 1230 to the outward-facing side 1232 and/or one or more fixation devices. In certain embodiments, a pair of parallel holes 1278 form a guide for pins 1280 (See FIG. 13) as part of a bone attachment feature. Advantageously, the holes 1278 may be angled with respect to a bone such as the first metatarsal. The angle for the holes 1278 may be customized based on the patient and the amount of adjustment desired for the first metatarsal.	152	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	FIG. 13 illustrates a perspective view of a first cuneiform 210 and first metatarsal 230 with one embodiment of a cutting guide 1300 secured to the two bones. The cutting guide 1300 includes pins 1280 in the holes 1240 to secure the cutting guide 1300 to the bones. (Pins 1280 for hole 1240a and hole 1240b and hole 1240c are omitted to facilitate certain disclosure.)	153	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	More specifically, the cutting guide 1053 may have a first end 1054 and a second end 1055, each of which has a bone attachment feature 1056. The bone attachment features 1056 may be used to secure the first end 1054 and the second end 1055 to the second bone segment 1042 and the heel 1050, respectively. The first end 1054 may have a first bone engagement surface 1057 that is shaped to match a corresponding contour on the second bone segment 1042, and the second end 1055 may have a second bone engagement surface 1058 that is shaped to match a corresponding contour on the heel 1050. Thus, the cutting guide 1053 may naturally lie flush with the surface of the calcaneus 1000, in the optimal position on the calcaneus 1000 to facilitate resection of the calcaneus 1000 to divide the second bone segment 1042 from the heel 1050. The cutting guide 1053 may have a guide feature 1059, such as a slot, that can be used to guide a cutter to form a single cut between the second bone segment 1042 and the heel 1050.	132	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	FIG. 14 illustrates a perspective view of a first cuneiform 210 and first metatarsal 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.	155	Added by DJM 2 2022	2/25/22, 12:00 AM
View Edit Delete	PER-10	At this stage in a surgical procedure, the cutting guide 1400 is placed on the first cuneiform 210 and the first metatarsal 230 and pins 1280a-d are connected to the bones through the respective holes 1240. Next, a surgeon uses the guide features of the cutting guide 1400 to reset the first cuneiform 210 and the first metatarsal 230. Then, a surgeon may insert pins 1280e,f into holes 1278 of the alignment feature 1260a. Alternatively, in another embodiment, a surgeon may insert pins 1280e,f into holes 1278 of the alignment feature 1260a before resecting the first cuneiform 210 and/or first metatarsal 230.	156	Added by DJM 2 2022	2/25/22, 12:00 AM
