View Edit Delete	PER-24	FIG. 7 illustrates an exemplary system 700 for remediating a condition present in a patient’s foot, according to one embodiment. The system 700 can include one or more fasteners 710, one or more resection guides 720, and one or more complementary components 730. While a system 700 can be used for a variety of procedures, one or more features, components, and/or aspects of the system 700 may be particularly suited for one or more osteotomies on one or more bones of a structure such as a patient’s foot, ankle, wrist, hand, shoulder, or the like.	215	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	In certain embodiments, the one or more fasteners 710 can include one or more permanent fasteners and/or one or more temporary fasteners. Typically, the fasteners 710 may be used during a variety of different steps of a procedure. Temporary fasteners are often used because they can securely hold bone or parts/fragments of bones while steps of the procedure are conducted. A common temporary fastener that can be used with system 700 is a K-wire, also referred to as a pin, guide pin, and/or anchor pin. Permanent fasteners 710 such as bone screws, bone staples, sutures, tethers or the like may also be used in a surgical procedure.	216	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	The one or more resection guides 720 assist a surgeon in performing different resection or dissection steps for an osteotomy or other procedure. In certain embodiments, a resection guide 720 includes one or more resection features 722 and one or more bone attachment features 724. The resection features 722 can take a variety of forms and/or embodiments. In one embodiment, the resection features 722 take the form of a cut channel or slot or other opening.	217	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	The resection features 722 provide a guide for a surgeon using a cutting tool to resect a bone, one or more bones, or other tissues of a patient. In certain embodiments, the resection features 722 may guide a surgeon in performing a resection, and osteotomy, and/or a dissection.	218	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Similarly, the bone attachment features 724 can take a variety of forms and/or embodiments. The bone attachment features 724 may serve to secure the resection guide 720 and/or other instrumentation to one or more bones and/or one or more other structures. Often, a bone attachment feature 724 can take the form of a hole in and/or through the resection guide 720 together with a temporary fastener such as a K-wire, pin, or guide pin.	219	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	The bone attachment features 724 facilitate attachment (at least temporarily) of a resection guide 720 to one or more bones, or bone fragments, of a patient. The bone attachment features 724 may include any of a wide variety of fasteners or structures including, but not limited to, holes, spikes, prongs, screws, fastening devices, and/or the like. Effective connection of the resection guide 720 to one or more bones across a joint and/or to one or more bones can ensure that cut surfaces are formed in desired locations and orientations and mitigate removal of hard tissue and/or soft tissue in undesired locations and/or orientations.	220	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	In certain embodiments, a resection guide 720 may include one or more bone engagement surfaces 726 and/or one or more landmark registration features 728. In certain embodiments, a landmark registration feature 728 may extend from one or more sides or ends of a resection guide 720 and engage with one or more landmarks of a bone or joint or anatomical structure of a patient. Registration of the landmark registration feature 728 to a landmark of a bone or joint can serve to confirm and/or ensure that a surgeon has located a desired placement and/or orientation for a resection guide 720.	221	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	In certain embodiments, the bone engagement surfaces 726 are patient-specific: contoured to match a surface of: one or more bones and/or bone surfaces the resection guide 720 contacts during the procedure or one or more joints proximal to the resection guide 720 during the procedure. Alternatively, or in addition, the bone engagement surface 726 may not be patient-specific, and may, or may not, contact a bone surface during use of the resection guide 720. In one embodiment, a skin contact surface may be used in addition to, or in place of, a bone engagement surface. Those of skill in the art appreciate that one or more sides of any of the members of the system 700 may include one or more bone engagement surfaces 726. Consequently, one or more sides of the fasteners 710, the resection guide(s) 720, the complementary components 730, navigation guides 792, and/or the implants 794 may include one or more bone engagement surfaces 726.	222	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	In certain embodiments, the resection guides 720 and/or aspects of the resection guides 720 may be integrated into other components and/or instruments, such as a pin guide, a trajectory guide, an alignment guide, or the like.	223	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	The complementary components 730 serve to assist a surgeon during one or more steps of a procedure. Those of skill in the art appreciate that a number of components can serve as complementary components 730. One or more of the features, functions, or aspects of the complementary components 730 can include patient-specific features.	224	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Examples of complementary components 730 include, but are not limited to, an alignment guide 740, a rotation guide 750, a reduction guide 760, a compression guide 770, a positioning guide 780, a fixation guide 790, navigation guides 792, and/or one or more implants 794. In general, the complementary components 730 serve to assist a surgeon in performing the function included in the name of the complementary component 730. Thus, an alignment guide 740 can help a surgeon align bones, parts of bones, or other parts of a patient as part of a procedure. A rotation guide 750 can help a surgeon rotate one or more bones, parts of bones, or other parts of a patient as part of a procedure. In one embodiment, a rotation guide 750 may hold one bone fragment stable while another bone fragment is rotated into a desired position.	225	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	A reduction guide 760 can help a surgeon position and/or orient one or more bones, parts of bones, or other parts of a patient as part of a procedure in order to reduce the bone, bones, bone parts, or other parts and/or in order to position and/or orient the bone, bones, bone parts, or other parts to a desired position and/or orientation. In certain embodiments, aspects and/or features of a reduction guide 760 can be integrated into one or more other components of an osteotomy system 700, such as components of the complementary components 730. A compression guide 770 can help a surgeon compress one or more bones, parts of bones, or other parts of a patient together or against an implant as part of a procedure. In certain embodiments, compression guide 770 can be a separate instrument such as a compressor and/or a combined compressor/distractor. The compressor / distractor can be used to compress two or more cut faces formed by an osteotomy until fixation is deployed or distract bones or parts of bones involved in a procedure. In certain embodiments, a compression guide 770 may serve a dual purpose as both a compression guide 770 and as a positioning guide 780. The same instrument may be used to both translate and/or rotate bones or bone fragments and compress two or more cut faces formed by an osteotomy until fixation can be deployed.	226	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	A positioning guide 780 (also referred to as a positioner) can help a surgeon position one or more bones, parts of bones, or other parts of a patient as part of a procedure. For example, a positioning guide 780 may hold one bone or bone fragment stable and hold one or more other bone fragments in a desired position while permanent or temporary fixation is deployed. In certain embodiments, the positioning guide 780 may hold bone fragments in a reduced position, and thus may function as both a positioning guide 780 and/or a reduction guide 760.	227	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	In certain embodiments, the positioning guide 780 may be designed and fabricated to be patient-specific. The patient-specific aspects can include a patient-specific bone engagement surface, a predefined angle for reorienting one or more bone or bone parts within one or more planes, a predefined position for bone attachment features 724 or fasteners 710, a predefined or patient-specific offset or amount of translation that is provided, or the like. Alternatively, or in addition, the positioning guide 780 may be selected from a kit, collection, or repository of a number of positioning guides 780: each having a different configuration for one or more aspects/attributes of the positioning guide 780. For example, each member of the repository/kit may include a different positioning angle (repositioning or correction angle), the angles may differ by 2 degrees for example. In such an embodiment, each positioning guide 780 may not be patient-specific to a particular patient but may provide the desired amount of positioning to meet the goals of the surgeon. In certain embodiments, a preoperative plan generated based on the present disclosure may include a recommendation for the positioning guide 780 to be used, even if the recommended positioning guide 780 is not patient-specific to the particular patient.	228	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	A fixation guide 790 can help a surgeon in completing one or more temporary or permanent fixation steps for one or more bones, parts of bones, or other parts of a patient as part of a procedure. The fixation guide 790 may include and/or may use one or more components of a fastener or fixation system including implant hardware of the fastener or fixation system.	229	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Those of skill in the art will appreciate that the other complementary components 730 may each have functions, purposes, and/or advantages with respect to one or more anatomical parts of the patient. Alternatively, or in addition, the other complementary components 730 may each have functions, purposes, and/or advantages with respect to one or more instruments and/or one or more anatomical parts of the patient. For example, a trajectory guide may be a type of alignment guide 740 in that the trajectory guide facilitates alignment of fixation with the desired location and/or trajectory/orientation with respect to one or more anatomical parts of the patient. Alternatively, or in addition, a trajectory guide may also be considered a type of fixation guide 790 because the trajectory guide facilitates deployment of one or more fasteners 710.	230	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Advantageously, the system 700 can help a surgeon overcome one or more of the challenges in performing an osteotomy procedure, particularly on bones of a hand or of a foot of a patient, such as on the forefoot, midfoot, or hindfoot. One challenge during an osteotomy procedure can be maintaining control of, and/or position, and/or orientation of a bone, one or more bones, and/or bone pieces/fragments, particularly once a resection or dissection is performed. Advantageously, the fasteners 710, resection guide(s) 720, and/or complementary components 730 can be configured to assist in overcoming this challenge.	231	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Advantageously, system 700 can help a surgeon in positioning, placing, and/or orienting a resection guide accurately. Modern techniques may include preoperative planning, simulation, or even practice using computer models, 3D printed models, virtual reality systems, augmented reality systems or the like. However, simulations and models are still different from actually positioning a resection guide on a patient’s bone, joint, or body part during the procedure. System 700 can include a number of features, including patient-specific features, to assist the surgeon with the positioning. In one embodiment, the resection guide 720 can include one or more landmark registration features 728.	232	Added by DJM Jan 2024	1/6/24, 10:01 PM
View Edit Delete	PER-24	Advantageously, the system 700 can help a surgeon in securing guides of the osteotomy system 700, such as a resection guide, as well as how to readily remove the guide (e.g., resection guide) without disturbing a reduction, shifting, reorienting, or repositioning one or more bones or parts of bones while removing the guide. In certain embodiments, the system 700 is configured to permit removal of a guide while keeping temporary fasteners in place for use in subsequent steps of an osteotomy procedure. Alternatively, or in addition, system 700 may facilitate positioning of temporary fasteners during one step of a wedge osteotomy procedure for use in a subsequent step of the wedge osteotomy procedure. Removal of a guide during an osteotomy procedure can be particularly challenging where translation and/or rotation of the bones involved in the osteotomy procedure is required for the success of the osteotomy procedure. Advantageously, system 700 accommodates translation and/or rotation of the bones during the osteotomy procedure while facilitating a successful outcome for the osteotomy procedure.	233	Added by DJM Jan 2024	1/6/24, 10:01 PM
