Advantageously, the fixation guide 3890 references off of fastener 2010a and fastener 2010b to position guides for deployment of fixation. For example, the fixation guide 3890 may include an arm 3892 that extends posteriorly and couples to one or more sleeves 3894 that are configured to receive guide pins 3896. While certain embodiments may include certain aspects of the fixation guide 3890 set as defaults, those of skill in the art will appreciate each aspect of the design and/or configuration of the fixation guide 3890 may be patient-specific and can be customized to a patient by using a model of one or more bones of a patient.

In Figure 39E, the fixation guide 3890 engages with fastener 2010a and passes between handles of the positioning guide 3810b and also engages with fastener 2010b. The fixation guide 3890 then extends posteriorly and positions two sleeves 3894 for deployment of guide pins 3896. The guide pins 3896 are deployed across the osteotomy and serve to guide permanent fixation such as cannulated bone screws or the like. In one embodiment, using embodiments of the present disclosure, a surgeon can determine where the guide pins 3896 will enter the bones preoperatively using a bone model of one or more bones of a patient and can adjust a trajectory for one or more of the guide pins 3896 and/or a location of entry for the guide pins 3896.

Figure 40C is a rear/medial view of one example embodiment of a resection guide 3820 that can be used in the osteotomy system 3800. Figure 40C illustrates a bone engagement surface 3830 that may be patient-specific and can be used to register the resection guide 3820 to a bone of a patient. Advantageously, the bone engagement surface 3830 can be generated based at least in part on a bone model of a bone of a patient.

In the illustrated embodiment, the alignment features of the positioning guide 3810a may extend from a lateral side 4114 to a medial side 4116 at an angle other than perpendicular each of the sides. Advantageously, the angle used for one or more of the alignment features may be predetermined and/or may be patient-specific. Those of skill in the art will appreciate that other aspects of the alignment features may be predetermined and/or patient-specific. For example, the position of the alignment features may be patient-specific.
