Abstract:
1. A hip-joint prosthesis having a shaft, fastened on a shaft head, which couples to a hall head which in turn is inserted in a rotatable manner in the hemispherical recess of a socket insert, the socket insert being coupled with a hip socket, wherein the shaft can be implanted in the femur, and the hip socket can be implanted in the pelvic bone, wherein a damping elements are arranged at coupling points of the shaft head with the ball head or at the coupling points of the socket insert with the hip socket or both, wherein the damping elements comprise a vibration-damping material, and wherein the damping elements shift vibration frequencies of the prosthesis during the movement so that the vibration frequencies are shifted into a non-audible range or acoustic phenomena associated with the prosthesis movement have a reduced sound pressure.
