Preparation of in Vivo Degradable Material Used in Bone Fixation

  • Received Date: 04 Dec 2001

  • To develop a kind of material with moderale strength and flexibility for bone fixation. First a series of product polymeric on chain reaction was obtained between poly D,L lactide and poly several lactore. Then to detect change regulation which tensile strength and degrading properties of product polymeric following extending chain agent and extending chain reaction condition, extending chain agent was selected and the best technology was formulated. With the above method, the polymeric of bone fixation was made, which is harmless to human body.The tensile strength of this product polymeric is 24.47 MPa, and its breaking elengation ratio is 1091%, to degrade it need six months.
