  • Patent number: 11224523
    Abstract: Orthopedic guide, and methods of using the guide, for alignment of bone under fluoroscopic imaging. In an exemplary embodiment, the guide may include a radiopaque rod, a radiolucent carrier, and a radiopaque indicator held by the carrier. The rod and the indicator may be parallel to the same plane, and may form an angle between one another of less than 90 degrees when projected orthogonally onto the plane. The rod may be configured to be aligned with an axis defined by one or more bones of the leg, and the indicator aligned with a joint of the leg, in an anterior-posterior, fluoroscopic view of the leg. The angle formed between the rod and the indicator may correspond to an anatomic orientation of the axis and the joint relative to one another in a frontal plane of the leg.
