Articulation prosthesis, in particular a hip prosthesis, with a self-damping property

Abstract

Abstract The present invention relates to an articulation prosthesis, in particular a hip prosthesis, consisting of an elongate body comprising an intramedullary rod and a body receiving a spherical head (3), this body being subdivided, in the direction of its length, into a part (4b) for supporting the spherical head and a part (1b) for anchoring in the bone, these parts being joined to one another by way of a damping connection, preferably defined by a direct connection of these parts which is formed, on the external face of the prosthesis, by a joining branch (11) holding the first part upright on the second part. In a preferred embodiment, the support part consists of a specially designed neck (4b) in the shape of a swan's neck, attached to the rod (1b), which forms the anchoring part, on its external face, this neck being profiled in such a way as to delimit with its base a recess (19) formed in the face opposite the rod, a rounded cavity (20) opening out on the inner face of the body of the prosthesis. <IMAGE>
