Life Spine Arx SAI Spinal Fixation System Nabs FDA Clearance

Life Spine, a medtech company focused on the surgical treatment of spinal disorders, recently announced the FDA clearance to market its ARx Sacral Alar Iliac (SAI) Spinal Fixation System. The system, what the company says is the “next generation in posterior fixation technology,” can be used through a SAI trajectory in S1 and/or S2 to provide maximum fixation across the sacroiliac joint.

Arx SAI features versatile implants paired with ergonomic instrumentation. This allows surgeons to construct customized solutions for each patient’s specific needs. The screw shank is based on the company’s SImpact SI self-harvesting screw design, which is “self-drilling and recruits autograft during insertion,” according to the press release.

Key features of the system include self-drilling screws that eliminate surgical steps and increase efficiency, a self-harvesting design that packs bone into fenestrations during insertion, a low-profile cobalt chrome tulip head that provides greater strength and supports all patient sizes, and a universal T25 hexalobe drive which ensures ease of use.

"ARx SAI advances our commitment to innovation, positioning us among the pioneering spine companies to offer an SAI screw within our Lumbar Spinal Fixation Systems portfolio,” said Mariusz Knap, senior vice president of sales and marketing, in the release. “ARx SAI delivers customizable solutions tailored to each patient, ensuring ease of use and versatile trajectory options.”
