摘要:
A hip joint prosthesis with a shaft fastened on the shaft head of which there is a ball head which in turn is inserted in a rotatable manner in the spherical recess of a socket insert and the socket insert is 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. To avoid transmission of vibrations, damping elements of a vibration-damping material are arranged at the coupling points of the shaft head with the ball head and/or of the socket insert with the hip socket.
