Abstract:
1. A method of doing surgical treatment in computer-assisted surgery for guiding an operator in inserting a cup implant of a hip joint implant into an acetabulum, comprising: positioning a trackable reference on a pelvis, the trackable reference being trackable in space so as to define a frame of reference; inserting any one of a provisional and a femoral implant into a femur; physically joining the provisional or femoral implant to the acetabulum with a tracked hip-joint device simultaneously coupled to a neck of the provisional or femoral implant and to the acetabulum; digitizing a neck axis of the provisional or femoral implant with respect to the frame of reference of the pelvis using a tracking of the tracked hip-joint device; and inserting the cup implant into the acetabulum by obtaining cup implanting information with respect to the orientation of said neck axis as a function of the tracking of the trackable reference.
