BONE PROSTHESIS

Artificial biocompatible material comprises an artificial bone part of desired shape and dimensions and a membrane composed mainly of an organic high-molecular cpd. The artificial bone part is wrapped completely in the membrane. The artificial bone part is made mainly from at least one material chosen from ceramic (1), carbon, metal (2) hard organic synthetic resin (3). It can also be made of sintered porous potassium phosphate. The ceramic (1) is composed of at least one substance chosen from alumina, zirconia, potassium phosphate. The metal (2) is chosen from stainless steel, titanium, tantalum, titanium alloy, nickel-chromium alloy, nickel-chromium-cobalt alloy, cobalt-chromium-molybdenum alloy. The hard organic synthetic resin (3) is chosen from high-density polyethylene resin, polytetrafluoroethylene resin, polymethylacrylate resin and silicone resin. The membrane is composed mainly of at least one organic high polymer material chosen from weave, knitted material, felt, net, organic high polymer film. It can be of sheet, tube or bag shape. The artificial bone part can, if necessary, be formed of a base and a coating layer composed of sintered ceramics and/or metal. Un matériau biocompatible artificiel comporte une partie osseuse artificielle (1, 4, 42) de forme et dimensions voulues, entourée d'une membrane (2, 5, 43) composée principalement d'un composé organique à poids moléculaire élevé. La partie officielle peut, le cas échéant, être formée d'une base (11) et d'une couche de revêtement (12).
