Early results show promise for 3D-printed titanium spine implants

Spinal Tech

Six-month data for Nexxt Spine's Matrixx 3D-printed titanium interbody implant showed strong results compared to poly-ether-ether-ketone devices.

Six-month data showed a "significant increase" in fusion rates at one- and two-level cases compared to PEEK devices, according to a July 12 news release. Matrixx implants had an 82 percent fusion rate while PEEK devices had a 25 percent fusion rate.

There were also promising results with the subsidence of Matrixx devices.

"The analysis of subsidence of the interbody devices had only 11.8 percent of levels for the Nexxt Matrixx device showing subsidence greater than 2 millimeters, while the PEEK device exhibited 55 percent of levels, showing that the Nexxt Matrixx technology has intrinsic benefits to patients and their outcomes," Jim Fried, the company's director of development and clinical studies, said in the release.

Research has been conducted at The Ohio State University Wexner Medical Center in Columbus.
