An October study in The Spine Journal compared the in vivo characteristics of RTI Surgical's 3D-printed PEKK Tetrafuse 3D Technology with PEEK and titanium-coated PEEK.
1. Eight ovine specimens were implanted with each biomaterial and analyzed for their osseointegrative abilities.
2. The study determined Tetrafuse had preferable bone growth properties to PEEK and titanium-coated PEEK without sacrificing structural integrity.
3. Tetrafuse features a nano-rough surface with antibacterial properties, which is designed to enhance fusion without effecting structural integrity or radiographic visibility.
