    Abstract: An assembly of a patient specific instrument and tracking system comprises a patient specific instrument having a body with a patient specific contact surface negatively shaped relative to a corresponding surface of a bone for complementary contact therewith. An inertial sensor unit with a preset orientation is connected to the body in a planned connection configuration, such that a geometrical relation between the contact surface and the inertial sensor unit is known. A tracking system has a tracking processor connected to the inertial sensor unit, a user interface, and bone orientation data related to the patient specific contact surface, the tracking processor producing orientation tracking data for the bone using the geometrical relation and the bone orientation data when the preset orientation of the inertial sensor unit is initialized, to output the orientation tracking data on the user interface.

    Abstract: A computer-assisted surgery system for guiding alterations to a bone, comprises a trackable member secured to the bone. The trackable member has a first inertial sensor unit producing orientation-based data. A positioning block is secured to the bone, and is adjustable once the positioning block is secured to the bone to be used to guide tools in altering the bone. The positioning block has a second inertial sensor unit producing orientation-based data. A processing system providing an orientation reference associating the bone to the trackable member comprises a signal interpreter for determining an orientation of the trackable member and of the positioning block. A parameter calculator calculates alteration parameters related to an actual orientation of the positioning block with respect to the bone.

    Abstract: A method and system for planning a creation of a cement bore in a bone comprises obtaining a virtual model of a bone, the model of the bone including a proximal bone surface, a distal bone surface, and a depth profile between the proximal bone surface and the distal bone surface. A planned positioning of a first implant selected to be implanted in the proximal bone surface is obtained. An identity of at least one tool used to alter the proximal bone surface to receive the first implant in the planned positioning and obtaining geometry data for the at least one tool is obtained. A cement bore required in the bone using the geometry data of the at least one tool and the planned positioning of the first implant is generated.

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 computer-assisted surgery system comprises instruments adapted to be used to perform tasks related to surgery. A reference device is in a fixed relation to a bone. A rotating magnet creates a magnetic field plane, the rotating magnet being connected to one of the instrument and the reference device. A magnetometer on the other of the instrument and the reference device produces signals as a function of at least its orientation relative to the magnetic field plane. A processing unit tracks said orientation of the instrument relative to the bone using said signals from the magnetometer subjected to the magnetic field plane.
