KNEE JOINT PROSTHESIS

A prosthesis in which the deepest point on the concave upper surface (15) of the shin member (5) is located substantially further forward than the geometrical centre of said upper surface; a guide pin (16) is substantially located at said deepest point and includes a body (17) with a circular cross-...

Beschreibung
Zusammenfassung:	A prosthesis in which the deepest point on the concave upper surface (15) of the shin member (5) is located substantially further forward than the geometrical centre of said upper surface; a guide pin (16) is substantially located at said deepest point and includes a body (17) with a circular cross-section and a head (18) which is wider than the body (17) and also has a circular cross-section; and a groove (11) in an intermediate plate (8) has a cross-section substantially matching the shape of the guide pin (16), so that it is pivotably and slidably engageable by said pin (16) with a reduced vertical clearance. Cette prothèse est caractérisée en ce que: le creux maximum de la face supérieure concave (15) de l'élément tibial (5) est situé sensiblement en avant du centre géométrique de cette face supérieure; le pion de guidage (16) est situé sensiblement au niveau de ce creux maximum et comprend un corps (17) de section transversale circulaire et une tête (18) de plus grande largeur que le corps (17), également de section transversale circulaire; et la rainure (11) aménagée dans le plateau intermédiaire (8) a une section transversale correspondant sensiblement au profil du pion de guidage (16), c'est-à-dire qu'elle peut recevoir ce pion (16) avec possibilité de pivotement et de coulissement mais avec une possibilité réduite de jeu vertical.
