"Positioner" or "positioning guide" refers to any structure, apparatus, surface, device, system, feature, or aspect configured to position, move, translate, manipulate, or arrange one object in relation to another. In certain embodiments, a positioner can be used for one step in surgical procedure to position, arrange, orient, and/or reduce one bone or bone fragment relative to another. In such embodiments, the positioner may be referred to as a bone positioner. In certain embodiments, the term positioner or positioning guide may be preceded by an adjective that identifies the structure, implement, component, or instrument that may be used with, positioned by, and/or guided by with the positioner. For example, a “pin positioner” may be configured to accept a pin or wire such as a K-wire and serve to position or place the pin relative to another structure such as a bone. … more "Positioner" or "positioning guide" refers to any structure, apparatus, surface, device, system, feature, or aspect configured to position, move, translate, manipulate, or arrange one object in relation to another.

As used herein, "registration" refers to a method, process, module, component, apparatus, and/or system that seeks to achieve precision in the alignment of two objects. One object may serve as a source object and the other object may serve as the destination object. The source object and destination object may each be physical objects and/or one object or the other may be a model of an object, the model maintained, represented, and managed within a computer. The goal of the registration operation is to coordinate, align, or arrange the source object and the destination object in to a substantially matching relationship relative to each other. In one example, a source object may be a physical device, implant, or instrument designed and configured to contact a surface of the destination object. Accordingly, the two connecting surfaces may be configured to each have a substantially matching contour (one the inverse of the other). In this example, the destination object may be a natural object such as a bone of a patient. The contour of the destination object may be obtained by using medical imaging and models derived from the medical imaging. In the process of registering the source object to the destination object two surfaces of the objects may be brought into contact and one object, or the other, or both, may be moved relative to each other until each protrusion from one objects fits within a corresponding recess, depression, void, or groove of the other object and/or the other object's surface and vice versa. When such alignment and/or coordination of the source object and destination object is accomplished the source object is considered "registered" with destination object. In this example, the source object may be an instrument and destination object is a bone and the instrument is registered with the bone surface when the instrument is placed against the bone such that the contour of the surface of the instrument touching the surface of the bone have a matching/coordinate relationship (e.g., each protrusion on one surface extends into a corresponding recess, depression, or void of the other surface). … more As used herein, "registration" refers to a method, process, module, component, apparatus, and/or system that seeks to achieve precision in the alignment of two objects.
