    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.

    Abstract: A digitizer device comprises an elongated body and legs connected to the elongated body. At least one joint is between the legs and the elongated body such that free ends of the legs are displaceable relative to one another. An inertial sensor unit is connected to the elongated body, the inertial sensor unit having a preset orientation aligned with the elongated body. A table reference device comprises a body adapted to be fixed to an operating table. An inertial sensor unit is with a preset orientation related to the operating table. A patient coordinate system comprising orientation data obtained from the inertial sensor units of the digitizer device and the table reference device

    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.
