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. |

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 facilitates positioning of temporary fasteners during one step of the 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 wedge osteotomy procedure is required for the success of the wedge osteotomy procedure. Advantageously, the system 900 accommodates translation and/or rotation of the bones during the wedge osteotomy procedure while facilitating a successful outcome for the wedge osteotomy procedure. |

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 from 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 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). |

Those of skill in the art will appreciate that the resection guide(s) 920 may have a variety of shapes, sizes and configurations. In one embodiment, these attributes can each be customized and adapted to meet needs or preferences of patients, a patient’s anatomy, the nature of the deformity, and/or surgeon preferences. In certain embodiments, the resection guide(s) 920 can be sized to be small enough to support minimally invasive surgery techniques and large enough to provide the surgeon the desired view of the operating field for the procedure. In certain embodiments, the resection guide 920 include visualization features (e.g., pattern 1033, windows, open areas around the body 1032, and the like). The visualization features can serve as important markers to assist a surgeon in knowing that the resection guide 920 is properly placed, positioned, oriented, seated, registered relative to other anatomical structures during a surgical procedure. In particular, a surgeon can confirm intraoperatively that steps of the procedure match the information, steps, and/or plan set forth in a preoperative plan. Advantageously, the features of the resection guides 920 can facilitate one or more osteotomies as well as other steps in a surgical procedure. |
