Raynham, Massachusetts-based DePuy Synthes is launching in the U.S. a novel line of titanium integrated interbody implants for spine surgery.
DePuy Synthes’ New 360° Titanium Integrated Interbody Implants

Brand named PROTI 360°, this is a family of integrated titanium interbody devices for patients with degenerative disc disease in the neck and back. According to DePuy Synthes, PROTI 360° is the only titanium-integrated Polyetheretherketone (PEEK) that offers 360 degrees of titanium integration.
Furthermore, the titanium integrated surface of the PROTI 360° promotes the attachment and growth of bone-forming cells.
According to DePuy, “Data presented at a recent podium presentation during the International Society for the Advancement of Spine Surgery Meeting showed calcium deposition, which is an indicator of early bone formation, was 470% higher with the PROTI 360° Technology than PEEK alone and 305% higher than titanium alone just one day after device testing.”
The other key feature of PROTI 360° is that DePuy Synthes’ engineers designed the implants for better bond strength between the materials, fortified titanium edges, and no exposed corners. The purpose is to prevent delamination, a process in which titanium coatings separate from the PEEK implant where the two materials meet.
“The ability to maximize the potential for bone growth is fundamental to achieving the best possible patient outcomes in most reconstructive spinal fusion surgery,” said L. Erik Westerlund, M.D., surgeon and director of the St. Francis Spine Center, Columbus, Georgia.
“Utilizing innovative biomaterials like titanium-integrated PEEK designed to promote bone growth delivers a comprehensive alternative offering to surgeons that advances the standard for spine surgery patients.”
Nadav Tomer, worldwide president, DePuy Synthes Spine, told OTW, “We are excited to provide surgeons with a new offering for use with patients suffering from degenerative disc disease in the neck and back. The new PROTI 360° Family of Implants have been designed to promote bone growth following spinal fusion surgery. With 360 degrees of titanium integration into the external surfaces of the devices, the PROTI 360° Family of Implants maximizes the surface area for bone cell integration creating a favorable environment for bone growth. We look forward to continuing to bring differentiated products like this to the market to help many more spine patients.”

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
