The Spine Journal study evaluates bone growth in RTI Surgical's surface technology

Surface Technology

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.

Three insights:

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.
