ABSTRACT:
An adjustable hip joint endoprosthesis has an adjustable prosthesis head, which is connected with a stem that can be fixed in the femur. To absorb overloads, which would result in damage to the prosthesis part implanted into the femur and therefore in another implantation, a limiting element is provided. This limiting element is arranged in the prosthesis head and absorbs the overload by deformation, fracture or, in the case of a frictionally engaged connection, by sliding. After the occurrence of an overload, the limiting element must be replaced or re-adjusted.
