Abstract

L'invention concerne un composant d'appui prothétique pour le remplacement d'articulations comportant un premier élément sur lequel est disposée une première couche magnétisée (26), où la première couche magnétisée (26) comporte un pôle (N) orienté dans une direction proximale, normale à la surface (20) du premier élément et un second élément sur lequel est disposée une seconde couche magnétisée (36). Le second élément est conçu pour venir au contact du premier élément, et la seconde couche magnétisée (36) comporte un pôle équivalent (N) orienté dans une direction distale, normale à la surface du second élément, moyennant quoi le pôle (N) de la première couche magnétisée (36) est opposé au pôle équivalent (N) de la seconde couche magnétisée (36), de sorte qu'une force de répulsion se crée entre les deux. Le composant d'appui prothétique comporte en outre une couche résistant à la corrosion (24, 34) couvrant les surfaces des premier et second éléments adjacents aux première et seconde couches magnétisées (26, 36) et une couche résistant à l'usure (22, 32) couvrant les surfaces des premier et second éléments adjacents à la couche résistant à la corrosion (24, 34) et formant une surface portante du composant d'appui prothétique.
