Abstract: A tool for digitizing a mechanical axis of a tibia using a computer-assisted surgery system is described. The tool includes upper and lower mounting ends interconnected by an alignment rod extending therebetween. The upper mounting end is releasably fastenable to an upper reference point on a tibial plateau and the lower mounting end includes a self-centering malleoli engaging mechanism having opposed caliper arms displaceable in a common plane relative to each other for clamping engagement with the medial and lateral malleoli of the ankle. At least one trackable member is mounted to the alignment rod of the tool and is in communication with the computer assisted surgery system for providing at least orientation information of the alignment rod. The mechanical axis of the tibia is parallel to the alignment rod and extends between the upper and lower reference points when the tool is mounted on the tibia.

Abstract: A method for determining a mechanical axis of a tibia using a tibial digitizer is disclosed. The method includes: determining an upper reference point on a tibial plateau corresponding to an entry point of the mechanical axis; fastening an upper mounting end of the tibial digitizer to the tibial plateau at the upper reference point; and fastening a lower mounting end of the tibial digitizer to medial and lateral malleoli of the ankle, by inwardly displacing opposed caliper arms of a self-centering malleoli engaging mechanism toward each other in a common plane until the caliper arms abut the malleoli. A lower reference point located at a midpoint between the medial and lateral malleoli is then determined by identifying a corresponding midpoint between the caliper arms when they are clamped onto the medial and lateral malleoli.

Abstract: The disclosed device for verifying a hip-knee-ankle angle includes a mounting base having a planar abutting surface adapted for direct abutting against a resected surface on a distal femur, and a first inertial sensor in communication with a computer assisted surgery (CAS) system to determine an orientation of the mounting base and to digitize a mechanical axis of the femur. A visual alignment guide element is pivotably mounted to the mounting base such that the angular position of the visual alignment guide element is adjustable so as to be visually aligned with a mechanical axis of a tibia. A difference between orientations of the mounting base and the visual alignment guide is calculated by the computer assisted surgery system to determine the hip-knee-ankle angle. The visual alignment guide may include a second inertial sensor and/or a laser emitting element.
