OSTEOINDUCTIVE BONE SCREW

摘要

A bone screw (19) and its method of manufacturing provices a low modulus osteoinductive bone screw with a high resistance to insertion torquing. The method includes the steps of pre-torquing a plurality of reinofrcing fibers (23), molding a polymer matrix to bond with the pre-torqued fibers, and whereing the screw apparatus is coated with an osteoinductive material such as hydroxyapatite or calcium phosphate.
