Abstract: A method for assisting in positioning the acetabular cup comprises orienting a cup positioning instrument with a cup thereon in an initial reference orientation relative to an acetabulum of a pelvis with the cup forming a joint with the acetabulum, the cup positioning instrument comprising an inertial sensor unit with pre-planned orientation data for a desired cup orientation based on at least one landmark of the pelvis, The cup positioning instrument is rotated to a desired abduction angle as guided by an interface of the cup positioning instrument, based on movements relative to at least one landmark. The cup positioning instrument is rotated to a desired anteversion angle as guided by the interface of the cup positioning instrument, based on movements relative to the at least one landmark. Upon reaching the desired cup orientation as indicated by the interface, the cup is impacted into the acetabulum.

Abstract: A computer-assisted surgery system comprises a calibrating instrument adapted to be applied to a pelvis in a known manner, and a surgical instrument. A computer-assisted processor unit operating a surgical assistance procedure and comprises at least one portable inertial sensor unit configured to be connected to the at least one calibrating instrument and the at least one surgical instrument, the portable inertial sensor unit outputting readings representative of its orientation. A geometrical relation data module provides a geometrical relation data between the orientation of the portable inertial sensor unit, of the calibrating instrument and of the surgical instrument. A coordinate system module sets a coordinate system of the pelvis in which an anterior-posterior axis of the pelvis is generally in a direction of gravity, and in which a medio-lateral axis of the pelvis is obtained from readings of the at least one portable inertial sensor unit on the calibrating instrument using the geometrical relation data therebetween. A tracking module tracks movements of the at least one surgical instrument relative to the coordinate system using readings from the inertial sensor unit on the surgical instrument using the geometrical relation data therebetween, and calculates navigation data for the movements, the navigation data relating the orientation of the surgical instrument to the orientation of the pelvis. An interface outputs the navigation data.

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.
