Abstract

L'endoprothèse comprend un élément d'articulation (1) ainsi qu'un élément de fixation (2) formant une seule pièce. L'élément d'articulation (1) présente un pôle supérieur et un pole inférieur. Le pôle supérieur a une surface de contact sphérique (3) ainsi qu'une surface interne sphérique (4). La génératrice (5) de la surface externe du pôle inférieur se compose d'une courbe convexe limitée par des surfaces en biais (7) sur les deux côtés à l'intérieur de la crête du premier os métatarsien, de manière à obtenir un élément courbé de remplacement de la crête de la tête de l'os métatarsien permettant de répartir uniformément la charge sur les pôles supérieur et inférieur.
