Nexxt Spine Introduces New Sacroiliac Joint Fusion System

Nexxt Spine LLC has officially launched the NEXXT MATRIXX SI System, a 3D-printed implant designed with a porous architecture for SI joint fusion procedures.

The 3D-printed NEXXT MATRIXX SI System adds to the company’s SI joint fusion solutions and gives surgeons more versatility in their procedural options.

“I am extremely excited about the launch of the NEXXT MATRIXX SI System,” said Dr. Phillip Esce, head of Neurosurgery at Spartanburg Regional Medical Center (South Carolina). “The versatility and technology the system offers is extremely beneficial to the wide variety of patient conditions and anatomies that I see. I believe the modulus of elasticity, surface texture and varied pore sizes of the NEXXT MATRIXX 3D Printed technology may contribute to improved outcomes for my patients.”

NEXXT MATRIXX SI System Highlights

• Proprietary NEXXT MATRIXX 3D printed technology, designed to enable active participation in the fusion process.
• Variable pore sizes: 300μm, 500μm, and 700μm.
• Minimized titanium material, resulting in a porous architecture.
• The micro-roughened porous structure of the NEXXT MATRIXX titanium gives the implants more surface area for bone apposition and potential bony integration than conventional SI implants.
• Dual thread profile designed to provide greater surface area and compression distally, while increasing fixation proximally in the cortical layer.
• Engineered fenestrations that allow for bony harvesting during insertion.
• Instruments designed to reduce steps, minimize working corridors, facilitate efficient implant placement, and support post-packing with graft materials.

“Following record revenue in 2024, recent regulatory clearances in Japan and Brazil, and the addition of several key leadership hires in the recent months, our product acceleration engine has only become more aggressive and experienced. We will continue to deliver advanced solutions in 2025 to deliver upon market improvements expressed by our surgeon partners with the goal of enhancing patient outcomes,” Nexxt Spine President Andy Elsbury stated. “We are thrilled to extend our NEXXT MATRIXX 3D printed technology to SI applications and enter one of the fastest-growing product segments in minimally invasive spine.”
