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 tibia cutting assembly includes a tibia cut guide with at least one cut slot. A guide rod has a guide holder mountable to the cut guide at a first end of the guide rod, and a second end of the guide rod is mountable non-invasively about a skin of a patient. The guide rod is extendable in length to displace the tibia cut guide and adjust a position thereof with respect to a tibia of the patient. The guide holder cooperates with the tibia cut guide to adjust an orientation of the tibia cut guide. A first inertial sensor is mountable to the guide holder and is displaceable therewith, and a second inertial sensor is mountable to the guide rod at the second end thereof.

Abstract: A pin placement instrument for placing a pin in a bone comprises an anatomical interface with a hook-like portion being opened in a lateral direction of the instrument to receive a bone therein in a planned position. A drill guide is connected to the anatomical interface and defining at least one guide slot in a longitudinal direction of the instrument. The guide slot has a lateral opening over its full length in the drill guide to allow lateral withdrawal of the instrument in said lateral direction with the pin placed in the bone passing through the lateral opening. A bushing is removably placed in said guide slot via said longitudinal direction in a planned fit, the bushing defining a throughbore aligned with the guide slot and adapted to receive the pin extending in said longitudinal direction when the bushing is in the guide slot for pin placement.

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 virtual model of the bone with the cement bore indicative of a relation between the cement bore and the distal bone surface is output.

Abstract: A system for tracking a femoral frame of reference in computer-assisted surgery comprises a sensor unit. The sensor unit is adapted to be secured to the femur. The sensor unit comprises accelerometer and gyroscope sensors that produce orientation data. A processing unit receives gyroscope and accelerometer data. The processing unit comprises a gyroscope-data calculator to provide calculated acceleration data resulting from movements of the femur, an accelerometer-data calculator to calculate measured acceleration data resulting from movements of the femur, and an acceleration comparator to relate an orientation of the sensor unit to the femur to define a femoral frame of reference. The femoral frame of reference is defined from the comparison between the calculated and the measured acceleration data. A sensor orientation interface provides orientation data for the femur from a tracking of the femoral frame of reference. A method for tracking a femoral frame of reference is also provided.

Abstract: A system for calculating a position and orientation of an acetabular cup in computer-assisted surgery comprises a first trackable reference secured to a pelvis, with a frame of reference being associated with the first trackable reference. A device is positionable between a femoral neck and the acetabulum of the pelvis in a known relation, the device having a second trackable reference. Sensors track the trackable references for position and orientation. A position/orientation calculator calculates a position and orientation of the frame of reference and of the device and for determining an orientation of the neck axis with respect to the frame of reference from the known relation at a desired position of the femur. An implant position/orientation calculator provides cup implanting information with respect to the orientation of said neck axis as a function of the tracking for position and orientation of at least the first trackable reference.
