The present invention is a joint surface replacement or joint prosthesis for the distal radioulnar (DRU) joint. The surface replacement comprises two parts, a radial component (1) and an ulnar component (2). Both components are designed to be inserted radially relative the radius (6) and the ulna (7). The radial (1) and ulnar (2) components are arranged to assure that the concave surface of the radial component may be pivoted and translated around the convex surface of the ulnar component during pivota- tion of the forearm.

Cette invention a trait à un remplacement de surface d'articulation, ou prothèse articulaire, destiné à l'articulation radio-cubitale distale (DRU). Le remplacement de surface comporte deux éléments, un composant radial (1) et un composant cubital (2). Ces deux composants sont conçus pour être insérés radialement par rapport au radius (6) et au cubitus (7). Ces composants, radial (1) et cubital (2), sont agencés de manière que la face concave du composant radial puisse pivoter et se déplacer autour de la face convexe du composant cubital lors du pivotement de l'avant-bras.
