[Load bearing capacity of CFK hip prosthesis with ceramic femoral heads]

Wear of the articulating surfaces of mating components of total hip endoprostheses is the most important technical factor limiting the functional lifetime of the prosthesis. Biolox ceramic femoral heads have been used successfully throughout the world for more than 20 years. In vitro tests and clinical results show that the artificial modular hip joint system employing a Caproman stem and a ball made of Biolox or Biolox -forte is resistant to mechanical failure. The threshold values for burst load and cyclic load prescribed by the FDA are achieved or bettered. Clinical results support those of the in vitro tests. The femoral head made of Biolox or Biolox -forte used in combination with cups and stems made of Caproman thus complies with the required standards.
