Abstract

La présente invention se rapporte à une cupule pour prothèse d'articulation fémorale comportant une coque creuse (10) de forme générale hémisphérique en matériau biocompatible présentant une face interne concave (20) destinée à recevoir un insert prothétique fixe ou mobile et une face externe convexe (30) conformée pour être ancrée dans une cavité cotyloïdienne du bassin d'un patient afin d'être solidarisée au tissu osseux constituant ladite cavité, caractérisée en ce que ladite face externe (30) de la coque (10) est revêtue d'au moins deux couches (32, 34) en matériau ostéo-compatible , une première couche circonférentielle de revêtement (32) disposée au niveau ou proche d'une partie polaire (31) de la coque (10) et une deuxième couche circonférentielle de revêtement (34) prolongeant la première couche (32) jusqu'à proximité d'une partie équatoriale (33) de la coque (10), les deux couches de revêtement (32, 34) étant réalisées dans des matériaux biocompatibles présentant des rugosités différentes.The present invention relates to a cup for a femoral joint prosthesis comprising a hollow shell (10) of generally hemispherical shape in biocompatible material having a concave internal face (20) intended to receive a fixed or mobile prosthetic insert and a convex external face. (30) shaped to be anchored in an acetabular cavity of the pelvis of a patient in order to be secured to the bone tissue constituting said cavity, characterized in that said outer face (30) of the shell (10) is coated with at least two layers (32, 34) of osteocompatible material, a first circumferential coating layer (32) disposed at or near a polar portion (31) of the shell (10) and a second circumferential coating layer ( 34) extending the first layer (32) to near an equatorial part (33) of the shell (10), the two coating layers (32, 34) being made of biocompatible materials with roughness different.
