PEEK replaces titanium in cervical implants


SpineNet (Winter Park, FL) has received 510(k) clearance from the U.S. Food & Drug Administration (FDA) for its new SpineNet ACC anterior cervical cage made of Zeniva polyetheretherketone (PEEK) rods from Solvay Specialty Polymers USA (Alpharetta, GA).

The SpineNet ACC cervical cage is designed to reproduce a tri-cortical iliac crest bone, providing structural support as an interbody spacer for anterior cervical fusions. The superior and inferior surfaces allow for close contact with the endplate surfaces for optimum stability and to resist subsidence.

The cages are offered in 10x12 mm and 12x14 mm footprints (5-10 mm height) with several sizing options. They are machined from various sizes of PEEK rods and have windows to allow bone growth, fusing the adjacent bony surfaces of the vertebrae. Radiopaque tantalum rod markers allow for improved positioning. The design includes teeth on the superior and inferior surfaces
