Patent ID: 7927338

Claim:
Surgical method for implantation of a total hip prosthesis, in which, per-operatively and successively: locating in space a bone of a femur and a bone of a pelvis of a patient to be treated; memorizing with a computer a plurality of measured positions of a given femoral prosthetic direction with respect to a cavity of the pelvis prior to positioning an acetabular component of the prosthesis in the cavity, the acetabular component having a predetermined cone of mobility defining an axis of revolution; determining at least one preferential position of the axis of revolution of the acetabular component without having to assemble the total hip prosthesis by comparing the measured positions of the femoral prosthetic direction with the predetermined cone of mobility and adjusting the position of the axis of revolution of the cone of mobility with respect to the cavity in the course of the surgical operation until the measured positions of the given femoral prosthetic direction are all located within the predetermined cone of mobility of the acetabular component; and impacting the acetabular component of the prosthesis in the cavity of the pelvis in the preferential position.
