In one embodiment, the export module 804 is configured to export the bone model 404, anatomic data 412, a patient-specific guide model 702, a preoperative plan 806, a fixator model 808, or the like. In this manner the custom instrumentation and/or procedural steps for a surgical procedure can be used in other tools. The preoperative plan 806 may include a set of step-by-step instructions or recommendation for a surgeon or other staff in performing a surgical procedure such as an osteotomy. The preoperative plan 806 may include images and text instructions and may include identification of instrumentation to be used for different steps of the surgical procedure. The instrumentation may include the patient-specific guide 406 and/or one or more fixators. In one embodiment, the export module 804 may provide a fixator model which can be used to fabricate a fixator for the surgical procedure.	219	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	The exports (404, 412, 702, 806, and 808) may be inputs for a variety of 3rd party tools 810 including a manufacturing tool, a simulation tool, a virtual reality tool, an augmented reality tool, an operative procedure simulation tool, a robotic assistance tool, and the like. A surgeon can then use these tools when performing a surgical procedure or for rehearsals and preparation for the surgical procedure. For example, a physical model of the bones, patient-specific guide 406, and/or fixators can be fabricated, and these can be used for a rehearsal operative procedure. Alternatively, a surgeon can use the bone model 404, preliminary guide model 438, and/or a fixator model to perform a simulated surgical procedure using an operative procedure simulation tool.	220	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	FIG. 9 illustrates an exemplary system 900, according to one embodiment. The system 900 can include one or more fasteners 910, one or more resection guides 920, and one or more complementary components 930. While a system 900 can be used for a variety of procedures, one or more features, components, and/or aspects of the system 900 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.	221	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	In certain embodiments, the one or more fasteners 910 can include one or more permanent fasteners and/or one or more temporary fasteners. Typically, the fasteners 910 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 900 is a K-wire, also referred to as a pin or guide pin.	222	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	The one or more resection guides 920 assist a surgeon in performing different resection or dissection steps for an osteotomy or other procedure. In certain embodiments, a resection guide 920 includes one or more resection features 922 and one or more bone attachment features 924. The resection features 922 can take a variety of forms and/or embodiments. Similarly, the bone attachment features 924 can take a variety of forms and/or embodiments. The resection features 922 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 922 may guide a surgeon in performing a resection and/or a dissection. The bone attachment features 924 serve to secure the resection guide 920 to one or more bones and/or one or more other structures. Often, a bone attachment feature 924 can include a hole in the resection guide 920 together with a temporary fastener such as a K-wire or pin.	223	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	The bone attachment features 924 facilitate attachment of a resection guide 920 to one or more bones, or bone fragments, of a patient. The bone attachment features 924 may include any of a wide variety of fasteners including, but not limited to, holes, spikes, fastening devices, and/or the like. Effective connection of the resection guide 920 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.	224	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	In certain embodiments, a resection guide 920 may include one or more bone engagement surfaces 926 and/or one or more landmark registration features 928. In certain embodiments, a landmark registration feature 928 may extend from one or more sides of the resection guide 920 and engage with one or more landmarks of a bone or joint or anatomical structure of a patient. Registration of the landmark registration feature 928 to a landmark of a bone can serve to confirm that a surgeon has located a desired placement and/or orientation for a resection guide 920.	225	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	In certain embodiments, the bone engagement surfaces 926 are patient-specific: contoured to match a surface of: one or more bones the resection guide 920 contacts during the procedure or one or more joints proximal to the resection guide 920 during the procedure. Alternatively, or in addition, the bone engagement surface 926 may not be patient-specific, and may, or may not, contact a bone surface during use of the resection guide 920. 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 900 may include one or more bone engagement surfaces 926. Consequently, one or more sides of the fasteners 910, the resection guide(s) 920, the complementary components 930, and/or the implants 996 may include one or more bone engagement surfaces 926.	226	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	The complementary components 930 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 930. One or more of the features, functions, or aspects of the complementary components 930 can include patient-specific features.	227	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	Examples of complementary components 930 include, but are not limited to, an alignment guide 940, a rotation guide 950, a reduction guide 960, a compression guide 970, a positioning guide 980, a fixation guide 990, and/or one or more implants 996. In general, the complementary components 930 serve to assist a surgeon in performing the function included in the name of the complementary component 930. Thus, an alignment guide 940 can help a surgeon align bones, parts of bones, or other parts of a patient as part of a procedure. A rotation guide 950 can help a surgeon rotate one or more bones, parts of bones, or other parts of a patient as part of a procedure.	228	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	A reduction guide 960 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. A compression guide 970 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. A positioning guide 980 can help a surgeon position one or more bones, parts of bones, or other parts of a patient as part of a procedure.	229	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	In certain embodiments, the positioning guide 980 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 924 or fasteners 910, or the like. Alternatively, or in addition, the positioning guide 980 may be selected from a kit, collection, or repository of a number of positioning guides 980: each having a different configuration for one or more aspects/attributes of the positioning guide 980. 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 980 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 980 to be used, even if the recommended positioning guide 980 is not patient-specific to the particular patient.	230	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	A fixation guide 990 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 990 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.	231	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	One example of a complementary components 930 may include a compressor / distractor. The compressor / distractor can be used to compress or distract bones or parts of bones involved in a procedure.	232	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	Advantageously, the system 900 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 910, resection guide(s) 920, and/or complementary components 930 can be configured to assist in overcoming this challenge.	233	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	Advantageously, the system 900 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. The system 900 can include a number of features, including patient-specific features, to assist the surgeon with the positioning. In one embodiment, the resection guide 920 can include one or more landmark registration features 928.	234	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	Advantageously, the system 900 can help a surgeon in securing guides of the osteotomy system 900, 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 900 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, the system 900 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, the system 900 accommodates translation and/or rotation of the bones during the osteotomy procedure while facilitating a successful outcome for the osteotomy procedure.	235	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	Advantageously, the components of the system 900 can be specifically designed for a particular patient. Alternatively, or in addition, the components of the system 900 can be specifically designed for a class of patients. Each of the components of the system 900 can be designed, adapted, engineered and/or manufactured such that each feature, attribute, or aspect of the component is specifically designed to address one or more specific indications present in a patient. Advantageously, the cuts made for the osteotomy procedure can be of a size, position, orientation, and/or angle that provides an optimal osteotomy with minimal risk of undesirable resection. In one embodiment, the components of the system 900 can be configured such that an osteotomy is performed that enables a correction in more than one plane in relation to the parts of the body of the patient. For example, cut channels or resection features 922 in a resection guide 920 can be oriented and configured such that when the bones are fused/fixated the correction results from translation, rotation, and/or movement of bones or bone parts in two or more planes (e.g., sagittal and transverse) once the fragments or bones are reduced.	236	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	In certain embodiments, the exemplary system 900 may include a plurality of fasteners 910, resection guides 920, and/or complementary components 930. For example, a surgeon may plan to resect a plurality of osteotomies from the bone(s) in order to accomplish a desired correction. In one example, one or more wedge segments may be resected from a medial side of a patient's foot and another one or more wedge segments may be resected from a lateral side of the patient's foot. These wedge segments may extend part way into the foot, or through from one side of the foot to the other. Of course, multiple wedge segments may be formed on one side of the foot as well.	237	Added by DJM Jan 2024	1/3/24, 4:26 AM
View Edit Delete	PER-16	Additionally, a surgeon may use one or more components in an exemplary system 900 to make multiple cuts in the bone(s). The multiple cuts may be centered over or around an apex of a deformity or positioned at other locations within the foot such that when the multiple cuts are made, any resected segments removed, or added bone void fillers introduced, and/or bones and/or bone fragments translated and/or rotated the combined angles, surfaces, removed segments, and/or added portions cooperate to provide a desired correction. Each of the components of the exemplary system 900 can be identified, defined, and reviewed using the apparatuses, systems, and/or methods of the present disclosure.	238	Added by DJM Jan 2024	1/3/24, 4:26 AM
