Centinel Spine® derived its name from the “Sentinel Sign” — the radiographic confirmation of a successful fusion anterior to the interbody device.

As a company, Centinel Spine began operations in August 2008, through the merger-acquisition of two pioneering medical device companies: Raymedica, LLC and Surgicraft LTD.

The Foundation

Founded in 1990, Raymedica became the recognized leader in nucleus replacement devices through the development of revolutionary products like the PDN® and HydraFlex®. Throughout its 18-year history, the company developed pioneering technologies and surgical approaches to the spine that helped thousands of patients restore function, reduce back pain, and avoid more invasive procedures. Raymedica was also the first company to develop a system for the Antero-Lateral Trans-Psoas Approach (ALPA)—implanting the PDN device via lateral access to the spine.

Clinical Origins

UK-based Surgicraft started spine-focused operations eight years earlier and, in 1988, launched the revolutionary titanium Hartshill Horseshoe—the first Stand-Alone/No Profile® anterior lumbar interbody fusion device in the world. This first-of-its-kind device was the basis for future generations of the market-leading Integrated Interbody™ technology platform known today as STALIF®.

STALIF technology has a 30-year clinical history, with over 65,000 devices implanted, and still remains the only stand-alone device demonstrating biomechanical equivalence to anterior plate and cage constructs in independent peer-reviewed publications.

Expansion into Total Disc Replacement

The company’s leadership in anterior column reconstruction was further strengthened through its recent acquisition of the prodisc® Total Disc Replacement technology platform—the most extensive cervical and lumbar motion-preserving reconstruction portfolio available today. The prodisc technology is the most studied and clinically-proven Total Disc Replacement system in the world, aligning with Centinel Spine’s focus on the proven clinical efficacy of its products. The prodisc design has been validated with over 125,000 device implantations and a reported reoperation rate of less than 1%. With the addition of prodisc, Centinel Spine stands alone as the only company with comprehensive motion preserving and fusion solutions for both cervical and lumbar anterior column reconstruction.

Today & Beyond

Since its founding, Centinel Spine has evolved into the largest, privately-held spine company focused on anterior column reconstruction. The company provides 16 differentiated product families that help thousands of patients around the world. Today, Centinel Spine still embraces the pioneering culture developed at both Raymedica and Surgicraft, continuing on its corporate mission:

To become the worldwide leading company addressing spinal disease anteriorly with the widest breadth & depth of technology platforms.

To provide clinically-proven products that help patients and allow individuals to continue to function at a high level.

To be a catalyst of change in the spine market.
