An orthopedic implant comprising a thermoplastic polymer or a composite comprising, in one embodiment, polyetheretherketone reinforced with 10% by volume of glass fibers, with an elastic modulus approximating the elastic modulus of bone. A porous coating is formed on the implant surface by creating
An orthopedic implant comprising a thermoplastic polymer or a composite comprising, in one embodiment, polyetheretherketone reinforced with 10% by volume of glass fibers, with an elastic modulus approximating the elastic modulus of bone. A porous coating is formed on the implant surface by creating a roughness thereon, by coating the surface with hydroxyapatite or by embedding a biocompatible material such as titanium in the surface. A two piece embodiment of the implant is joined and locked together, after the opposite ends of each piece are inserted in the medullary canal, using an interlocking mechanism comprising a fluted protrusion on one piece and a corresponding fluted cavity in the other piece with the fluted portions being complementarily tapered.
