Title (EN) HINGE TYPE BONE JOINT PROSTHESIS
(FR) PROTHESE D"ARTICULATION OSSEUSE DU TYPE A CHARNIERE
Abstract: front page image
(EN)A prosthesis for replacing a hinge type bone joint includes a first component (12) having a body portion (16) defining a plurality of generally semi-circular distal bearing surfaces (46, 54) extending therefrom and a proximally extending intramedullary canal stem (18). A second component (14) has a body portion (62) defining a convex posterior surface, a plurality of semi-circular grooves (81, 82) configured to matingly receive the distal bearing surfaces of the first component, and a distally extending intramedullary canal stem (64). The second component may further define a laterally positioned capitulum process (90) having a distal surface (94) adapted to be abutted against by the head of a radius bone (89) upon implantation in cases where the prosthesis replaces an elbow joint. The first component defines an aperture (40) and the second component includes a hook-like member (70) adapted to detachably and hingingly interconnect the components in a slipfit fashion.
(FR)Une prothese de remplacement d"une articulation osseuse du type a charniere comprend un premier composant (12) ayant un corps (16) definissant une pluralite de surfaces portantes distales semi-circulaires (46, 54) s"etendant a partir du corps et une tige s"etendant dans le canal intramedulaire (18). Un second composant (14) possede un corps (62) definissant une surface posterieure convexe, une pluralite de rainures semi-circulaires (81, 82) concues pour que les surfaces portantes distales du premier composant viennent s"y accoupler, et une tige s"etendant distalement dans le canal intramedulaire (64). Le second composant peut en outre definir une apophyse de capitulum positionnee lateralement (90) ayant une surface distale (94) adaptee pour que viennent appuyer la tete d"un radius (89) dans le cas d"implant ou la prothese remplace l"articulation d"un coude. Le premier composant definit l"ouverture (40) et le second composant comprend un organe en forme de crochet (70) concu pour relier entre eux les composants de maniere detachable et articulee par enclenchement lateral.
