    摘要： A CAS system and method for guiding an operator in inserting a femoral implant in a femur as a function of a limb length and orientation of the femoral implant with respect to the femur, comprising a reference tool for the femur, a registration tool, a bone altering tool and a sensing apparatus. A controller is connected to the sensing apparatus to: i) register a frame of reference of the femur by calculating surface information provided by the registration tool as a function of the position and orientation of the registration tool provided by the sensing apparatus, and/or retrieving in a database a model of the femur; ii) calculate a desired implant position with respect to the frame of reference as a function of the limb length; and iii) calculate a current implant position and orientation in relation to the desired implant position with respect to alterations being performed in the femur with the bone altering tool, as a function of the position and orientation of the bone altering tool provided by the sensing apparatus and of a digital model of a femoral implant provided by the database. The database is connected to the controller for the controller to store and retrieve information relating to an operation of the controller. The computer-assisted system may be used to guide an operator in inserting a pelvic implant in an acetabulum as a function of an orientation of the pelvic implant with respect to the pelvis.

    摘要： 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.
