View Edit Delete	PER-12	Figures 22A-22G illustrate views of a pin guide of an osteotomy system, such as osteotomy system 2000, according to one embodiment. In one embodiment, the osteotomy system 2000 may include at least one complementary component 1930. The complementary component 1930 may include one or more pin guides 2200. In certain embodiments, the complementary component 1930 may include a posterior pin guide 2202 and an anterior pin guide 2204. In one embodiment, a single pin guide 2200 may be used as both the posterior pin guide 2202 and the anterior pin guide 2204. Using a single pin guide 2200 may promote re-use and/or may facilitate fabrication of pin guides 2200. Alternatively, or in addition, the posterior pin guide 2202 may be configured differently from the anterior pin guide 2204.	359	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	The pin guide 2200 serves to position and/or orient one or more pins for deployment into bone of a patient. Advantageously, the pin guide 2200 may be designed using a model of the bone and/or a model of other components of the osteotomy system 2000. In particular, a pin guide 2200 may enable fasteners 2010 in another component such as the resection guide 2020 to be parallel with each other and one or more fasteners 2010 to be deployed into a bone at a non-parallel angle relative to each other. Pins in the bone at non-parallel angles can be used for reduction and/or compression and/or fixation during a step of a surgical procedure.	360	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	In the illustrated embodiment, the posterior pin guide 2202 and the anterior pin guide 2204 may be similar. Advantageously, a user or surgeon can define the posterior pin guide 2202 and the anterior pin guide 2204 to be patient-specific. For example, one pin guide 2200 may have a default or standard configuration and the other pin guide (e.g., the posterior pin guide 2202 and/or the anterior pin guide 2204) may have a different, customized, and/or patient-specific configuration.	361	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	In one embodiment, the osteotomy system 2000 includes a resection guide 2020a configured to cooperate with the one or more pin guides 2200 to position one or more pins. Figure 22A illustrates a resection guide 2020a with two pin guides 2200 (e.g., a posterior pin guide 2202 and an anterior pin guide 2204). A pin guide 2200 may include an arm 2206 configured to engage at least one of a posterior resection feature 2022a and an anterior resection feature 2022b. The arm 2206 may be connected to a bone engagement feature 2208 configured to receive a fastener such as a pin or K-wire.	362	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	The arm 2206 engages a resection feature 2022 and connects the bone engagement feature 2208 to the resection feature 2022. In one embodiment, the arm 2206 includes an opening 2220 sized and/or configured to receive a bridge (e.g., posterior bridge 2062 and/or anterior bridge 2068) of a resection feature 2022 (e.g., a posterior resection feature 2022a and/or an anterior resection feature 2022b). In certain embodiments, the arm 2206 may engage the resection feature 2022 by sliding the opening 2220 over the bridge. Alternatively, or in addition, another part of the arm 2206 may slide down into one or more openings of a resection feature 2022. In one embodiment, the opening 2220 may include a closed end that includes two corners that meet at right angles. Similarly, a top surface of the bridge (e.g., posterior bridge 2062 and/or anterior bridge 2068) may be rectangular such that top edges of the bridge engage the two corners of the opening 2220 when the arm 2206 is engaged with a bridges as desired or, when the arm 2206 is fully engage with the resection feature 2022.	363	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	The bone engagement feature 2208 can serve to guide and/or position a pin during deployment into a bone. In certain embodiments, each of the pin guides 2200 include an arm 2206 and a bone engagement feature 2208. The arm 2206 may include a body 2210 and a coupler 2212. The body 2210 connects the coupler 2212 and the bone engagement feature 2208.	364	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	The bone engagement feature 2208 can be implemented using a hole 2214 and a fastener 2216. Advantageously, pin guides 2200 (e.g., a posterior pin guide 2202 and an anterior pin guide 2204) enable a fastener 2216 to be deployed where needed for a surgical procedure. In the illustrated embodiment, fasteners 2216 may be needed in a posterior bone fragment 2114 and/or in an anterior bone fragment 2116 for one or more steps of a surgical procedure.	365	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	In the illustrated embodiment, the pin guides 2200 (e.g., a posterior pin guide 2202 and an anterior pin guide 2204) serve to enable deployment of fasteners 2216 a distance, such as a predetermined distance from a posterior side 2036 and/or an anterior side 2034 of a resection guide 2020. The fasteners 2216 engage with the holes 2214 and the holes 2214 and arm 2206 cooperate to direct the fasteners 2216 into the bone in a desired position and/or angle. The fastener 2216 may engage the hole 2214 in a friction fit. In certain embodiments, once a fastener 2216 is deployed through a hole 2214, the pin guide 2200 may be removed by leaving the fastener 2216 in place and sliding the pin guide 2200 up and off of the fastener 2216.	366	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	The coupler 2212 enables the pin guide 2200 to be connected and/or disconnected from a complementary component 1930. The complementary component 1930 may serve as a reference or guide for the placement, positioning, and/or orientation of fasteners 2216 into bone and/or bone fragments during a surgical procedure. Those of skill in the art will appreciate that the coupler 2212 may be implemented using a variety of configurations.	367	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	In the illustrated embodiment, the coupler 2212 is implemented as a fin 2218 that includes an opening 2220. The opening 2220 may be sized and/or configured to receive a bridge (e.g., posterior bridge 2062 and/or anterior bridge 2068) of a resection feature 2022. In certain embodiments, the coupler 2212 may engage the resection feature 2022 by sliding the opening 2220 over the bridge. Alternatively, or in addition, the fin 2218 may slide down into one or more openings of a resection feature 2022 and secure the orientation and/or position of the pin guide 2200.	368	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	In another embodiment, the coupler 2212 may couple or connect to a different structure of a complementary component 1930. For example, in one embodiment, the coupler 2212 may couple to one or more fasteners 2010 deployed in a resection guide 2020.	369	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	Figure 22B is a perspective view of one example pin guide 2200. Figure 22B illustrates that the coupler 2212 (or fin 2218) may extend from the body 2210 parallel to the bone engagement feature 2208. Figure 22C is a perspective view.	370	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	Figure 22D is a distal side view of one example pin guide 2200. Figure 22D illustrates one embodiment of a coupler 2212 and/or a fin 2218 with an opening 2220. Figure 22E is a proximal side view of one example pin guide 2200.	371	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	Figure 22F is a superior side view of one example pin guide 2200. Figure 22F illustrates the hole 2214. In one embodiment, the hole 2214 extends from one end of the bone engagement feature 2208 to the other end. Figure 22G is an inferior side view of one example pin guide 2200.	372	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	Referring now to Figure 22A, in one embodiment, while the coupler 2212 and bone engagement feature 2208 may extend from the body 2210 in parallel, a fastener 2216 deployed using the pin guide 2200 may deploy at a non-perpendicular angle in relation to the bone. In the illustrated embodiment, this is because as the pin guide 2200 engages with the resection feature 2022 (e.g., posterior resection feature 2022a and/or anterior resection feature 2022b) the coupler 2212 can assume the same angle in relation to the body 2028 as the opening of the resection feature 2022. Consequently, the fastener 2216 deployed using the bone engagement feature 2208 enters the bone at substantially the same angle as an opening of the resection feature 2022. Since the angle of the opening of the resection feature 2022 can be patient-specific, the angle of deployment for one or more fasteners 2216 can also be patient-specific.	373	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	Those of skill in the art will appreciate that varies aspects of the pin guide 2200 can be configured and/or customized to meet the needs of a particular patient, surgeon for a surgical procedure. Alternatively, or in addition, at least one of the arm 2206 and the bone engagement feature 2208 can include one or more patient-specific features. These patient-specific features may be defined at least in part based on a bone model of the bone the pin guide 2200 will be used with. For example, a distance of a fastener 2216 from an osteotomy can be controlled and/or set by defining a length of the body 2210. An angle of entry for a fastener 2216 can be controlled by way of an angle of a resection feature 2022 and/or an angle of a coupler 2212 and/or a fin 2218 relative to an angle of a bone engagement feature 2208 used for deployment of the fastener 2216. Advantageously, each of these angles, configurations, aspects, and/or features can be customized and designed in a model of the pin guide 2200 before the pin guide 2200 is fabricated for use. These angles, configurations, aspects, and/or features may be patient-specific features for a pin guide 2200.	374	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	Referring still to Figure 22A, in one embodiment, the resection guide 2020a includes a posterior resection feature 2022a and an anterior resection feature 2022b. The osteotomy system 2000 may include a posterior pin guide 2202 and an anterior pin guide 2204. The posterior resection feature 2022a is configured to receive an arm 2206 of the posterior pin guide 2202 and the anterior resection feature 2022b is configured to receive an arm 2206 of the anterior pin guide 2204. The posterior pin guide 2202 includes an arm 2206 that connects a planar fin (e.g., fin 2218) to a bone engagement feature 2208 that includes an opening, such as hole 2214, and a posterior pin 2220. The anterior pin guide 2204 includes an arm 2206 that connects a planar fin (e.g., fin 2218) to a bone engagement feature 2208 that includes an opening, such as hole 2214, and an anterior pin 2222.	375	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	In the embodiment of Figure 22a, the posterior pin guide 2202 is configured to guide the posterior pin 2220 into a posterior bone fragment 2114 (See Figure 21J) parallel to an osteotomy (e.g., first osteotomy 2046) formed using the posterior resection feature 2022a. The anterior pin guide 2204 is configured to guide the anterior pin 2222 into an anterior bone fragment 2116 (See Figure 21J) parallel to an osteotomy (e.g., second osteotomy 2048) formed using the anterior resection feature 2022b. Alternatively, or in addition, the anterior pin guide 2204 is configured to guide the anterior pin 2222 into an anterior bone fragment 2116 (See Figure 21J) substantially parallel to an osteotomy (e.g., second osteotomy 2048) formed using the anterior resection feature 2022b. The anterior pin 2222 may be deployed at an angle that is not parallel to the osteotomy (e.g., second osteotomy 2048) such that when the osteotomy is reduced a predetermined degree of compression is applied to the cut faces of the osteotomy.	376	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	Advantageously, fasteners 2216 (e.g., posterior pin 2220 and/or anterior pin 2222) deployed using the pin guide(s) 2200 may be used for subsequent steps in a surgical procedure. In one embodiment, the osteotomy system 2000 may include a positioning guide 2300 as one of the complementary components 1930. In one embodiment, for example, a posterior pin 2220 deployed by way of a posterior pin guide 2202 and an anterior pin 2222 deployed by way of an anterior pin guide 2204 are configured to receive a positioning guide 2300. In certain embodiments, depending on how various components of the osteotomy system 2000 are designed and/or fabricated a positioning guide 2300 may serve to position a posterior bone fragment 2114 and/or an anterior bone fragment 2116, reduce an osteotomy, and/or compress two bone fragments together. Alternatively, or in addition, the positioning guide 2300 may also serve as a correction guide, a rotation guide, an alignment guide, and/or the like.	377	Added by DJM Jan 2024	1/6/24, 10:03 PM
View Edit Delete	PER-12	The positioning guide 2300 may be similar in form and/or function to the positioning guide 1980 described herein. Alternatively, or in addition, the positioning guide 2300 may be configured differently. In one embodiment, the positioning guide 2300 facilitates positioning one or more bones, bone fragments, implants, and/or instruments for one or more steps of a surgical procedure.	378	Added by DJM Jan 2024	1/6/24, 10:03 PM
