Abstract
The invention relates to a joint endoprosthesis and a method for fixing the seat thereof. The endoprosthesis has a shaft that is anchored in the marrow cavity of a tubular bone, and an ultra source that is placed in or on the shaft and the radiation characteristics of which enable ultrasound waves to reach a gap between the spongiosa of the tubular bone and the surface of the external covering of the shaft. The associated method applies impinging ultrasound waves upon the gap.
