FIELD: medical engineering.
SUBSTANCE: device has cup and head members having engageable smooth surfaces. Both cup and head members have bushing manufactured from isotropic pyrolytic carbon and plate manufactured from isotropic pyrolytic carbon rigidly attached to the bushing by means of chemical bonds without foreign material being used. Connection strength is not lower than strength of the material itself.
EFFECT: high reliability of endoprosthesis.
