Abstract：
 The invention discloses a bone repairing material, which is high in mechanical intensity. The adopted technical project: chitin ramification 0.01-10% in solution form added in or compounded in synthetical high-molecular materials such as bone cement system, polylactic acid, etc. The chitin ramification can be phosphatized chitin, phosphatized chitosan, carboxyl-butyl chitosan and carboxylic vitriolic esterified chitosan. The bone repairing material is a reliable endo-degradable tissue repairing and curing material, having wide application value in repairing tissues (such as bone, cartilage, teeth).
