ABSTRACT:
A joint endoprosthesis has a first implant component which can be attached to a first epiphysis, and a second implant component which can be attached to a second epiphysis of two epiphyses forming a joint, with the first implant component and the second implant component each having articular surfaces for the formation of a swivel joint, and with a sliding piece being provided that in addition enables a rotational movement and a translational movement of the epiphyses with respect to each other. The joint endoprosthesis is characterized in that the first implant component has a housing that can be embedded in the first epiphysis and anchored in the first epiphysis; a first sliding body is mounted in the housing so as to be rotatable about the axis of rotation; a second sliding body is mounted in the first sliding body so as to be translatable in a direction roughly transverse to the axis of rotation; the second sliding body has a portion that projects out of the housing, and is fitted with an articulation surface against which the second implant component rests; and the second sliding body, by a sliding surface, rests against a mating sliding surface provided on the housing.
