Title
(EN) METHOD AND APPARATUS FOR DISTAL RADIOULNAR JOINT (DRUJ) ARTHROPLASTY
(FR) PROCÉDÉ ET APPAREIL POUR UNE ARTHROPLASTIE D'ARTICULATION RADIO-CUBITALE INFÉRIEURE (DRUJ)
Abstract
(EN)
Apparatus for reconstructing a joint of the sort comprising a first bone having a first articular surface and a second bone having a second articular surface, wherein the first articular surface and the second articular surface engage one another, the apparatus comprising: a prosthesis for replacing at least a portion of the first articular surface of the first bone, the prosthesis comprising: a prosthesis plate for positioning against an outside surface of the first bone; and a prosthesis body connected to the prosthesis plate, the prosthesis body comprising a first prosthetic articular surface which generally matches the shape and size of the first articular surface.
(FR)
L'invention porte sur un appareil pour reconstruire une articulation de la sorte comprenant un premier os ayant une première surface articulaire et un second os ayant une seconde surface articulaire, la première surface articulaire et la seconde surface articulaire venant en prise l'une avec l'autre, l'appareil comprenant : une prothèse pour remplacer au moins une partie de la première surface articulaire du premier os, la prothèse comprenant : une plaque de prothèse destinée à être positionnée contre une surface extérieure du premier os; et un corps de prothèse relié à la plaque de prothèse, le corps de prothèse comprenant une première surface articulaire prothétique qui correspond généralement à la forme et à la dimension de la première surface articulaire.
