    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 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 glenosphere-implant positioning device comprises a coupling body having a first portion adapted to contact a spherical portion of a glenosphere implant, and a second portion adapted to contact an underside portion of the glenosphere implant, such that the coupling body is configured to be releasably coupled to a glenosphere implant in a known manner. A guide is connected to the coupling body and is configured to be slidingly engaged to a guide pin representative of a desired implanting orientation of the glenosphere implant or to a periphery of an implanted baseplate. A method for installing a glenosphere implant on an implanted baseplate is also provided.
