Claim Text:
1. A method of doing surgical treatment with a tracking system in computer-assisted surgery for guiding an operator in inserting a femoral implant of a hip joint implant in a femur as a function of a limb length and orientation of the femoral implant, comprising: obtaining a frame of reference of the femur, the frame of reference being trackable in space; obtaining a digital model of a geometry of a femoral implant, and a digital model of a geometry of a tooling end of a rasp; calculating a desired implant insertion for the femoral implant with respect to the frame of reference of the femur, as a function of the limb length; calculating alterations being made to a femur with a real-time tracking of the rasp altering the femur for receiving the femoral implant and with the digital model of the geometry of the tooling end of the rasp; and determining a current implant insertion with respect to the desired implant insertion, the current implant insertion being calculated as a function of the digital model of the femoral implant and the calculated alterations.
