Abstract

L'invention concerne des prothèses ou implants chirurgicaux comprenant une structure composée consistant en un support métallique solide cohérent et un revêtement poreux d'au moins un métal adhérant sur le support et s'étendant sur au moins une partie de sa surface, d'une épaisseur d'au moins environ 100 mu , de préférence d'environ 100 à 1 000 mu et ayant une porosité d'environ 10 à 40 %, le métal étant sensiblement non corrodable et non dégradable par les humeurs de l'organisme, le revêtement poreux comportant plusieurs pores interstitiels reliés entre eux, distribués à peu près uniformément et ayant une dimension au moins suffisante pour permettre la croissance du tissu osseux dans le revêtement. Selon l'invention le revêtement poreux est formé par décomposition thermique de particules d'au moins un composé d'au moins un métal pur et frittage des particules décomposées thermiquement pour provoquer la liaison des particules de métal pur entre elles et avec le support en leurs points de contact entre elles et avec ce dernier.
