PURPOSE:To provide a fixing action for a while after embedding, to enable a composite material for recovering a bone to be gradually absorbed in a organism, and to enable the material to be applicable to a small broken bone part by a method wherein an organism absorptive calcium phosphate series compound or a composition containing the compound is carried on a sheet or a netform substance formed by an organism absorptive high molecular substance. CONSTITUTION:An usual organism absorptive high molecular material is absorbed by an organism tissue and freed from property to injure an organism and polyamino acid and polylactate which can be molded to form a sheet or netform substance. Various appetites, and tricalcium phosphate, which are gradually dissolved in an organism to discharge ion phosphate and calcium ion and serves as s trigger for forming a bone and acts as a feed source of calcium and phosphorus for a new bone, are listed as an organism absorptive calcium phosphate series compound, and a mixture of two or more kinds may be used. This constitution enables a title composite material to be used in a way to be wound around a broken bone part, to be applicable to a fine broken bone part where a nail-in-marrow can not be used, to provide a fixing action for a while and to be gradually absorbed in an organism for disappearance. |
