"Bone Wedge" refers to a geometric shape of one or more bones characterized by having two flat, planar, and/or inclined sides or surfaces that converge to form an edge. A bone wedge resembles a triangular prism, with one end wider or thicker than the other. (© ChatGPT Aug. 3 Version, Modified, accessed chat.openai.com/chat Sept. 28, 2023). In certain implementations, the edge formed by the two converging sides is within a bone or set of bones from which the bone wedge is formed. In other implementations, the edge formed by the two converging sides is outside of a bone or set of bones from which the bone wedge is formed. |

"Window" refers to an opening and/or a plurality of openings in a body, side, wall, side door, roof, vehicle, system, component, or other structure that allows the passage of electromagnetic radiation including radio ways, x-rays, visible light, light, and the like. A window may also permit passage of sound, gases, fluids, liquids, or other elements. (Search “window” on Wikipedia.com Aug 31, 2022. Modified. Accessed Sept. 21, 2022.). A window can be opaque, semi-opaque, translucent, radiolucent, or transparent. A window can include a single opening having a single geometric shape or a plurality of openings each of a single geometric shape or combination of a variety of geometric shapes. In certain embodiments, a window may be referred to as a radiolucent window. A radiolucent window may permit passage of some or all radio ways through the window. |

"Radiolucent" refers to any structure, apparatus, surface, device, system, feature, or aspect that permits radio waves to pass from one side of the radiolucent structure to the opposite side. The radio waves can be any radio wave including light, x-rays, and the like. A radiolucent structure, apparatus, surface, device includes structures that define an opening or hole (e.g., a structural opening) in the structure, apparatus, surface, device such that radio waves from one side of the structure, apparatus, surface, device pass through one or more openings or holes to an opposite side of the structure, apparatus, surface, device. A radiolucent structure, apparatus, surface, device also includes structures that comprise a solid material (e.g., no holes or openings, not a structural opening) that is configured to permit passage of one type of radio wave but not another type of radio wave. For example, a radiolucent structure, apparatus, surface, device may be made of a material such as a plastic or polymer which may prevent passage of one radio wave, such as light, from one side of the structure, apparatus, surface, device to the other, but may permit passage of another radio wave, such as X-rays from one side of the structure, apparatus, surface, device to the other. |

"Probe" refers to a medical instrument used to explore, identify, locate, or register to, wounds, organs, and/or anatomical structures including a joint or an articular surface. In certain embodiments, a probe can be thin and/or pointed. In one embodiment, a probe is connected, integrated with, and/or coupled to another structure or instrument. In such an embodiment, the probe may serve to facilitate proper positioning of the another structure or instrument. For example, the probe may be used to identify and/or locate a particular anatomical structure and the positioning of the probe may then cause the connected structure or instrument to also be positioned in a desired location relative to one or more anatomical structures. |

"Friction fit" refers to a type of joint or connection that is created between two components by means of friction. A joint or connection that is formed using a friction fit may or may not include the use of additional fasteners such as screws, bolts, or adhesives. In a friction fit, the components are designed or configured to fit tightly together, creating enough friction between the surfaces to hold them securely in place, at least temporarily. The friction force is generated by the compressive force that is experienced between the components and can be strong enough to prevent the components from separating under normal conditions.

As used herein, "osteotomy procedure" or "surgical osteotomy" or “osteotomy” refers to a surgical operation in which one or more bones are cut to shorten or lengthen them or to change their alignment. The procedure can include removing one or more portions of bone and/or adding one or more portions of bone or bone substitutes. (Search "osteotomy" on Wikipedia.com Feb. 3, 22, 2021. CC-BY-SA 3.0 Modified. Accessed Feb. 15, 2022.) As used herein, "patient-specific osteotomy procedure" refers to an osteotomy procedure that has been adjusted, tailored, modified, or configured to specifically address the anatomy, physiology, condition, abnormalities, needs, or desires of a particular patient. In certain aspects, one patient-specific osteotomy procedure may be useable in connection with only one patient. In other aspects, one patient-specific osteotomy procedure may be useable with a number of patients having a particular class of characteristics. In certain aspects, a patient-specific osteotomy procedure may refer to a non-patient-specific osteotomy procedure that includes one or more patient-specific implants and/or instrumentation. In another aspects, a patient-specific osteotomy procedure may refer to a patient-specific osteotomy procedure that includes one or more patient-specific implants, patient-specific surgical steps, and/or patient-specific instrumentation. |

"Wedge osteotomy" refers to an osteotomy procedure in which one or more wedges are used as part of the procedure. Generally, wedge osteotomies can be of one of two types, open wedge and closing wedge. The type of osteotomy refers to how the procedure changes the relation between two parts of a bone involved in the osteotomy. In an open wedge osteotomy, a wedge of bone or graft or other material is inserted in between two parts of a bone. Consequently, a wedge shape is "opened" in the bone. In a close wedge osteotomy or closing wedge osteotomy a wedge of bone is removed from a bone. Consequently, a wedge shape formed in the bone is "closed." |

"Metatarsal" is a bone of a foot of a human. In a human, a foot typically includes five metatarsals which are identified by number starting from the most medial metatarsal, which is referred to as a first metatarsal and moving laterally the next metatarsal is the second metatarsal, and the naming continues in like manner for the third, fourth, and fifth metatarsal. The metatarsal bone includes three parts a base which is a part that is at a proximal end of the metatarsal, a head which is a part that is at a distal end of the metatarsal, and a shaft or neck connects the base to the head. |

"Epiphyses" refers to the rounded end of a long bone, at long bone's joint with adjacent bone(s). Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate). At the joint, the epiphysis is covered with articular cartilage; below that covering is a zone similar to the epiphyseal plate, known as subchondral bone. (Search 'epiphysis' on Wikipedia.com 17 June 2022. Modified. Accessed Aug. 1, 2022.) "Metaphysis" refers to the neck portion of a long bone between the epiphysis and the diaphysis. The metaphysis contains the growth plate, the part of the bone that grows during childhood, and as the metaphysis grows the metaphysis ossifies near the diaphysis and the epiphyses. (Search 'metaphysis' on Wikipedia.com 17 June 2022. Modified. Accessed Aug. 1, 2022.) "Diaphysis" refers to the main or midsection (shaft) of a long bone. The diaphysis is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). The diaphysis is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs.

"Metaphyseal Diaphyseal Junction" or "MDJ" refers to an area of a long bone between the Metaphysis and the Diaphysis. This area can also include or be referred to as the epiphyseal plate (growth) plate. For certain surgical procedures, performing an osteotomy at or near the metaphyseal diaphyseal junction may be advantageous and desirable to promote rapid fusion of two cut faces formed in the osteotomy and bone growth to close the osteotomy, and / or may mitigate the risk of a nonunion of the osteotomy. |
