Avoid bone resorption to achieve long-term good bone retention.

Abstract

La présente invention concerne une prothèse d'articulation de la cheville en matériau macromoléculaire totalement organique qui comprend une prothèse du dôme astragalien (1), une malléole médiale tampon (2), et une prothèse osseuse angulaire (3). La prothèse de dôme astragalien est reliée au coussinet malléolaire médial, et le coussinet malléolaire médial est relié à la prothèse osseuse angulaire. La prothèse de dôme astragalien et la prothèse osseuse angulaire sont toutes deux constituées de polyétheréthercétone (PEEK) ou un dérivé de celle-ci. Le coussinet malléolaire médial est constitué de polyéthylène à poids moléculaire très élevé (UHMWPE). Un composant d'implant de la prothèse comprend un matériau macromoléculaire, réduire une allergie et la toxicité résultant d'un métal et la corrosion métallique. Un module d'élasticité d'un matériau de PEEK permet que le matériau de PEEK corresponde à un os réel, de manière à atténuer un effet de protection contre les contraintes. En outre, une surface de frottement par glissement de la prothèse par rapport à un cartilage articulaire réduit un problème d'usure.
