Abstract

Abstract Translated from French L'invention concerne les prothèses. Elle se rapporte à des prothèses ayant, éventuellement sur un élément de support de charge, une matière thermoplastique poreuse particulière, par exemple une polysulfone, ayant certaines propriétés bien particulieres telles qu'un diamètre moyen de pores compris entre 90 et 600 microns, des interconnexions de pores superieures à 50 microns, un module d'élasticité compris entre 1,72.10**9 et 2,07.10** 10 Pa, une porosité supérieure à 40 %, et une déformation totale par fluage qui est très faible. Application à la réalisation de prothèses qui favorisent une ossification irréversible. The invention relates to prostheses. It relates to prostheses having, optionally on a load-bearing element, a particular porous thermoplastic material, for example a polysulfone, having certain very specific properties such as an average pore diameter of between 90 and 600 microns, interconnections with pores greater than 50 microns, an elastic modulus of between 1.72.10 ** 9 and 2.07.10 ** 10 Pa, a porosity greater than 40%, and a total creep strain which is very low. Application to the production of prostheses which promote irreversible ossification.
