Abstract: An implant component which comprises a solid material region and a surface structure connected to the solid material region is disclosed. A coating is provided on the surface structure, said coating comprising, in addition to an At % proportion of Ti as a main component, at least one further coating component, wherein one of the at least one further coating components is silver having an At % proportion of 15-25 At %. The surface structure here comprises undercuts which are coated with said coating.

Abstract: Modular endoprosthesis for at least partial replacement of a tubular bone, comprising, as module components, a stem for insertion into a bone cavity of the tubular bone, and an end piece comprising a support body with a neck part arranged on the medial aspect thereof. Said module components being able to be coupled to each other and released from each other along a longitudinal axis of the shaft. The end piece has at least two different surface configurations on its support body, namely a closed surface (6?) on a medial aspect, and a porous configuration of the surface on the opposite, lateral aspect. The latter permits and positions the adhesion of muscle tissue, specifically without suturing. The muscle trauma caused by suturing, and the peak loads that occur at the respective suture points, can thus be avoided by virtue of the invention, by means of the location-specific direct adhesion of the muscle.
