Abstract: An ossicular prosthesis has first and second fastening elements, a connecting element and rib elements. The rib elements lead directly into coupling regions of the first fastening element within the head plate plane and are movably connected thereto. All rib elements are movably connected to a coupling element and are firmly but detachably connected during operation, the coupling element in turn being rigidly connected at the other end to either the first or the second fastening element. The rib elements form the connecting element with the coupling element and are spread sectionally radially from the longitudinal axis in the middle ear in situ with the introduction of a force parallel to the longitudinal axis and thus shorten the axial functional length of the prosthesis, but increase it with the introduction of a force anti-parallel thereto. The rib elements retain, in situ, their adjusted radial position when no force acts.
