New PROTI 360° Family of Implants from DePuy Synthes Is Designed to Enhance Spinal Fusion Surgery Outcomes

Approximately 400,000 patients undergo spinal fusion surgery annually to help reduce pain and nerve root inflammation in the US alone.¹ During this procedure, a disc is removed and an interbody spacer is implanted to potentially restore natural height between two vertebrae and create solid bone.

To maximize the potential for bone growth following this type of surgery, DePuy Synthes has introduced the PROTI 360° Integrated Titanium Family of Implants, the only titanium-integrated Polyetheretherketone (PEEK) that offers 360 degrees of titanium integration. PEEK is a biocompatible material with mechanical properties that resemble human bone, and the implants are radiolucent, which means surgeons can easily assess the bone healing process over time.² The new PROTI 360° Technology offering combines the benefits of PEEK and titanium in each device. The titanium integrated surface of the PROTI 360° Family of Implants creates a bioactive surface that promotes the attachment and growth of bone-forming cells.^3,4

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 470.4% higher with the PROTI 360° Technology than PEEK alone and 305.1% higher than titanium alone just one day after device testing.⁵ The PROTI 360° Family of Implants is designed with enhanced bond strength between the materials, fortified titanium edges, and no exposed corners 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, MD, 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."

The PROTI 360° Family of Implants includes the ACIS PROTI 360° System for cervical fusion and the T-PAL PROTI 360° System and CONCORDE PROTI 360° System for lumbar interbody fusion. The PROTI 360° Systems are compatible with ACIS, T-PAL and CONCORDE Systems instrument sets.

"With the launch of the PROTI 360° Family of Implants we are responding to the needs of spine surgeons with a differentiated technology to help advance the care of patients undergoing spinal fusion surgery," said Nadav Tomer, Global Platform Leader, DePuy Synthes Spine. "DePuy Synthes has one of the broadest spine portfolios in the world, and we continue to focus on innovation that strengthens our offering."
