"Bone condition" refers to any of a variety of conditions of bones of a patient. Generally, a bone condition refers to an orientation, position, and/or alignment of one or more bones of the patient relative to other anatomical structures of the body of the patient. Bone conditions may be caused by or result from deformities, misalignment, malrotation, fractures, joint failure, and/or the like. A bone condition includes, but is not limited to, any angular deformities of one or more bone segments in either the lower or upper extremities (for example, tibial deformities, calcaneal deformities, femoral deformities, and radial deformities). Alternatively, or in addition, “bone condition” can refer to the structural makeup and configuration of one or more bones of a patient. Thus bone condition may refer to a state or condition of regions, a thickness of a cortex, bone density, a thickness and/or porosity of internal regions (e.g. whether it is calcaneus or solid) of the bone or parts of the bone such as a head, a base, a shaft, a protuberance, a process, a lamina, a foramen, and the like of a bone, along the metaphyseal region, epiphysis region, and/or a diaphyseal region. "Malrotation" refers to a condition in which a part, typically a part of a patient's body has rotated from a normal position to an unnormal or uncommon position. |

As used herein, a "guide" refers to a part, component, member, or structure designed, adapted, configured, or engineered to guide or direct one or more other parts, components, or structures. A guide may be part of, integrated with, connected to, attachable to, or coupled to, another structure, device, or instrument. In one embodiment, a guide may include a modifier that identifies a particular function, location, orientation, operation, type, and/or a particular structure of the guide. Examples of such modifiers applied to a guide, include, but are not limited to, "pin guide" that guides or directs one or more pins, a "cutting guide" that guides or directs the making or one or more cuts, a placement, deployment, or insertion guide that guides or directs the placement, positioning, orientation, deployment, installation, or insertion of a fastener and/or implant, a "cross fixation guide" that guides deployment of a fastener or fixation member, an "alignment guide" that guides the alignment of two or more objects or structures, a "navigation guide" that guides a user in navigating a course or process or procedure such as a surgical procedure, a "resection guide" that serves to guide resection of soft or hard tissue, such as in an osteotomy, a "reduction guide" can serve to guide reduction of one or more bone segments or fragments, an "placement guide" that serves to identify how an object can be placed in relation to another object or structure, and the like. Furthermore, guides may include modifiers applied due to the procedure or location within a patient for which the guide is to be used. For example, where a guide is used at a joint, the guide may be referred to herein as an “arthrodesis guide.” |

“Hole” refers to a gap, an opening, an aperture, a port, a portal, a space or recess in a structure, a void in a structure, or the like. In certain embodiments, a hole can refer to a structure configured specifically for receiving something and/or for allowing access. In certain embodiments, a hole can pass through a structure. In other embodiments, an opening can exist within a structure but not pass through the structure. A hole can be two-dimensional or three-dimensional and can have a variety of geometric shapes and/or cross-sectional shapes, including, but not limited to a rectangle, a square, or other polygon, as well as a circle, an ellipse, an ovoid, or other circular or semi-circular shape. As used herein, the term “hole” can include one or more modifiers that define specific types of “holes” based on the purpose, function, operation, position, or location of the “hole.” As one example, a “fastener hole” refers to an “hole” adapted, configured, designed, or engineered to accept or accommodate a “fastener.” |
