Abstract
Orthopedic implants, particularly interbody spacers, have a combination of correct pore size and stiffness/flexibility. When the implants have the proper pore size and stiffness, osteocytes are able to properly bridge the pores of the implant and then experience a proper compressive load to stimulate the bone cells to form bone within the pores. An implant includes a body formed of an osteoconductive material and having a stiffness of between 400 megapascals (MPa) and 1,200 MPa. Additionally, the body includes a plurality of pores having an average size of between 150 microns and 600 microns. The pores permit the growth of bone therein. The body is formed of packs of coils which may be formed using an additive manufacturing process and using traditional orthopedic implant materials such as titanium and titanium alloys while still achieving desired stiffness and pore sizes of the implants.
