Claim:
1. A system for calculating a position and orientation of an acetabular cup in computer-assisted surgery, comprising: a first trackable reference adapted to be secured to a pelvis, with a frame of reference being associated with the first trackable reference; a device adapted to be positioned between a femoral neck and an acetabulum of the pelvis to simultaneously physically loin the femoral neck to the acetabulum, the device having a second trackable reference; sensors for tracking the first and second trackable references; a position/orientation calculator for tracking the frame of reference of the first trackable reference, and for tracking the device, and for determining an orientation of a neck axis of the femoral neck with respect to the frame of reference when the device simultaneously physically loins the femoral neck to the acetabulum; and an implant position/orientation calculator for providing cup implanting information with respect to the orientation of said neck axis as a function of information provided by the sensors tracking at least the first trackable reference.
