  • the invention relates to a hip joint prosthesis with a shaft, on the Schaft- head a ball head is fixed, which in turn is rotatably inserted in the calotte of a socket insert, and the socket insert is coupled to a H-pfanne, the shaft in the femur and the acetabulum in the Pelvic bones are implantable.

  • the vibrations emitted as a result of the occurrence of the stick-slip effect act as excitement and lead to the oscillation of the individual components of the artificial joint. If one or more of the natural frequencies of the components lie in the audible spectrum (approximately 16-20,000 Hz), they can be perceived acoustically by the patient as the wearer of the artificial hip joint prosthesis, for example in the form of so-called squeaking.

  • the invention has the object of developing a hip joint prosthesis according to the O-term of claim 1 so that no squeaking occurs.
  • damping elements made of a vibration-damping material are arranged at the coupling points of the shaft head with the ball head and / or the socket insert with the acetabular cup.

L'invention concerne une prothèse d'articulation de la hanche avec une tige (1) sur la tête (22) de laquelle est fixée une tête condylienne (2) qui elle-même est insérée en rotation dans la calotte d'un insert acétabulaire et l'insert acétabulaire (3) est couplé à une cupule acétabulaire (4). La tige (1) peut être implantée dans le fémur (20) et la cupule acétabulaire (4) dans le bassin (21). Pour éviter la transmission d'oscillations, l'invention propose de disposer aux emplacements de couplage de la tête de tige (22) à la tête condylienne (2) et/ou de l'insert acétabulaire (3) à la cupule acétabulaire (4) des éléments faits d'un matériau qui amortit les oscillations.
