Abstract: Presented is a hip cup for a hip joint acetabular prosthesis that includes a metallic outer cup and a cup body made of plastic inside the outer cup. To guarantee a movement- and deformation-free attachment of the cup body, the cup body is enclosed in tightly fitting fashion, toward the outer cup, by a metallic jacket, and the insert formed of cup body and jacket can be anchored in the outer cup in tightly fitting fashion with at least one attaching element.
