US-based implants maker RTI Surgical has launched a new technology to offer surgeons with three-dimensional (3D) printed polymer implant material for spinal interbody fusion.

The new TETRAfuse 3D Technology is said to provide trabecular bone ingrowth with simultaneous maintenance of radiolucency and mechanical properties similar to a bone.

TETRAfuse 3D printing process is designed to create a nano-rough surface on the whole implant to allow bony ingrowth across the disc space from endplate to endplate for deep implant osseointegration.

RTI Surgical CEO Camille Farhat said: “We are excited about the promise this technology holds for our surgeon customers and their patients.

“Being the first to offer surgeons a 3D printed interbody polymer optimised to participate in fusion marks another significant milestone for RTI in our quest to continuously deliver relevant and innovative products without compromise.”

The ability of the new technology to combine fusion process, bone-like mechanical properties and radiolucent imaging is intended to provide surgeons with the osseointegrative advantages of both titanium and allograft bone, along with the benefits of PEEK.
