View Edit Delete	PER-23	Referring still to FIGs. 9A through 9G, the body 732 may further have features that facilitate visualization of a user an orientation and/or axes of one or more bones of the midfoot. For example, in the illustrated embodiment, the resection guide 720 may include at least one alignment feature. An alignment feature may be integrated into the resection guide 720 or the alignment feature may be a separate feature from the resection guide 720. The alignment feature can be a strategically placed opening sized to hold a guide pin or K-wire such that the K-wire indicates a direction and/or trajectory of a bone or an axis of a bone.	288	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	In the illustrated embodiment, the first bone attachment feature 766 or the second bone attachment feature 768 may serve as both a bone attachment feature and as an alignment feature. In this manner, the first bone attachment feature 766 can provide both a bone attachment feature and an alignment feature in a single feature. In certain embodiments, the first bone attachment feature 766 and/or the second bone attachment feature 768 can be used as a reference marker or reference pin for use with other instrumentation used in a surgical procedure.	289	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	The landmark registration feature 728 serves to facilitate registration of a guide 720 to a surface of a bone and/or to one or more landmarks of one or more bones. The resection guide 720 can include one, two, or more landmark registration features 728. In the illustrated embodiment, the resection guide 720 may include one or two landmark registration features 728. The landmark registration features 728 can extend from one or more sides of the resection guide 720. In the illustrated embodiment, the landmark registration features 728 extend from a bone attachment feature 724. Those of skill in the art will appreciate that the landmark registration features 728 can have various lengths, widths, and thicknesses. Advantageously, the landmark registration features 728 can also include a bone engagement surface section 727 that may extend a bone engagement surface 726 on an anterior surface/side 734 (See FIG. 9H) of the resection guide 720.	290	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	In the illustrated embodiment, one landmark registration feature 728 extends from the posterior side 736 and one landmark registration feature 728 may extend from the lateral side 746. Advantageously, the landmark registration feature 728 can provide a surgeon with confidence and assurance in the placement and positioning of the resection guide 720 on a bone because the landmark registration feature 728 can be configured to engage with a particular landmark on the bone or other patient anatomy (e.g., a projection or a depression or cavity). Alternatively, or in addition, the landmark registration feature 728 can include a contoured bone engagement surface that can further facilitate registration of the landmark registration feature 728 and/or guide 720 with the bone. In this manner, a surgeon can be assured intraoperatively that the resection guide 720 is being positioned in accordance with a preoperative plan.	291	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	In certain embodiments, the landmark registration feature 728 can be shaped like a hook to engage a surface of bone. Alternatively, or in addition, the resection guide 720 may include a landmark registration feature 728 on different sides, together the landmark registration features 728 can engage one or more landmarks of a surface of the bone such that the surgeon can accurately position and register the resection guide 720 to the bone.	292	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	FIGs. 9E-9G illustrate alternative embodiments of a patient-specific resection guide 720. Those of skill in the art will appreciate that the resection guide 720 can have a variety of features, configurations, sizes and/or attributes that can be based at least in part on needs or preferences of patients, the nature of the deformity, and/or surgeon preferences.	293	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	FIG. 9E illustrates a resection guide 720e that, like resection guide 720c, includes an open end 729 on a dorsal side 742 and an open end 729 on the plantar side 738. In the illustrated embodiment, the resection guide 720e may include one or more auxiliary bone attachment features 752. The auxiliary bone attachment feature 752 can be an optional feature for a resection guide 720.	294	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	The auxiliary bone attachment feature 752 can serve a variety of purposes. For example, an auxiliary bone attachment feature 752 can serve to engage with one or more bones or bone fragments that are to be resected from the patient. For example, a surgeon may position the resection guide 720e, secure the resection guide 720e to one or more bones using the bone attachment features 724. Next, a surgeon may deploy a pin or K-wire in an opening of the auxiliary bone attachment feature 752 to engage with one or more bone fragments (e.g., a wedge) that will be resected when the surgeon resects using the resection features 722. After the resection, the resection guide 720e can be removed while a pin of the auxiliary bone attachment feature 752 remains in place. That pin can then be used to manipulate, reposition, and/or remove a resected bone fragment.	295	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	Alternatively, or in addition, an auxiliary bone attachment feature 752 can be included to provide additional engagement with one or more bones of the patient during the osteotomies. The auxiliary bone attachment feature 752 can be connected to the body 732. The auxiliary bone attachment feature 752 can include one or more openings configured to receive one or more fasteners 710. The one or more fasteners 710 engage one or more bones of the patient.	296	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	For example, suppose a patient has midfoot bones that have osteoporosis and/or are otherwise of a very fragile and brittle condition, a surgeon may decide to include one or more auxiliary bone attachment features 752 at various positions around the body 732. These auxiliary bone attachment features 752 can be strategically positioned using the bone model 404 (and/or a model of a resection guide 720) such that a fastener 710 in an opening of an auxiliary bone attachment feature 752 engages higher quality and/or stronger bone than the bone beneath one or more other openings in other bone attachment features 724. Advantageously, a position for an auxiliary bone attachment feature 752 can be determined by a surgeon (e.g., a user) of the resection guide 720. In this manner, the resection guide 720 can be further customized to the needs or preferences of a particular patient and/or surgeon.	297	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	Those of skill in the art will appreciate that a resection guide 720 may include one or more bone attachment features 724. Certain bone attachment features 724 may be positioned to engage with a resected segment, wedge, or bone fragment such as, for example, auxiliary bone attachment feature 752 and other bone attachment features 724 may engage with remaining bones or bone segments after resection. Furthermore, the resection guide 720, such as example resection guide 720, may include bone attachment features 724 that are strategically positioned in the resection guide 720 to serve as trajectory guides, attachment points, compression anchors, distraction anchors, reduction guides or the like. For example, bone attachment features 724 and the pins that can be strategically placed in a way that following the wedge resections, the pins can then be manipulated to aid in the reduction/correction of the osteotomies using specialized instrumentation and/or customized instrumentation or segmental compression blocks.	298	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	In addition, the bone attachment features 724 and associated pins can be designed, positioned, oriented, and utilized to target provisional and/or permanent fixation devices such as pins, staples, screws, bolts, beams, nail or strategically placed reduction wires that can be utilized for external devices such as external fixators.	299	Added by DJM Jan 2024	1/6/24, 9:56 PM
View Edit Delete	PER-23	Furthermore, customized guides can be placed over strategically placed pins used with bone attachment features 724 and these pins can be used for the purposes of pre-drilling fixation components such as screws or strategic placement of fixation, plates, staples, etc.	300	Added by DJM Jan 2024	1/6/24, 9:56 PM
