Abstract
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.
