    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 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.
