摘要:
A bone screw and its method of manufacturing provides a low modulus osteoinductive bone screw with a high resistance to insertion torquing. The method includes the steps of pre-torquing a plurality of reinforcing fibers, molding a polymer matrix to bond with the pre-torqued fibers, and wherein the screw apparatus is coated with an osteoinductive material such as BMP, growth factors, hydroxyapatite or calcium phosphate.
