A high-strength, biodegradable, organic polymer/inorganic particle composite material for bone fixation, which is prepared by mixing and dispersing a biocompatible, inorganic fine or ultrafine particle in an organic monomer and then polymerizing the organic monomer and thus exhibits remarkably improved mechanical strength, and also to a high-strength, biodegradable, organic polymer/inorganic particle composite material prepared thereby is disclosed. More particularly, the a high-strength, biodegradable, organic polymer/inorganic particle composite material for bone fixation is prepared by mixing and dispersing a calcium phosphorus compound or a calcium aluminate compound in a biodegradable organic monomer, at the amount of 0.5 to 60% by weight; and polymerizing the biodegradable organic monomer; and then forming the polymerized material into a desired shape. The synergistic, reinforcing effect of the inorganic fine particle is increased, so that the high-strength material for bone fixation can be prepared. Also, the biocompatible fine particle is used, so that a long-term side effect can be reduced. |
