Stryker launches Monterey AL interbody system

Monterey AL interbody system (Stryker)

Stryker has announced the launch of the Monterey AL interbody system, a standalone interbody fusion device designed for anterior lumbar interbody fusion (ALIF).

Monterey AL is made up of both solid and porous structures within a single implant, leveraging Stryker’s proprietary Tritanium in-growth technology, a material designed to mimic cancellous bone and provide an environment favourable to bone regeneration and fusion.1-4 New data demonstrates that undifferentiated stem cells grown on Tritanium exhibited osteogenic alkaline phosphatase without requiring growth factor supplements.5,6

Bala Giri, president and founder of the Texas Neuro Spine Institute (Dallas, USA), said: “No one understands 3D-printing like Stryker—the fact that they’ve been able to dial in the right mix of small, medium, and large pores in a reproducibly randomised matrix is incredible.

“Their growing body of pre-clinical data, specifically the cellular findings published most recently, makes my decision to go with these products very straightforward. Our goal with any implant is spinal fusion, and Stryker has taken a very intentional approach to designing the Tritanium cages with this goal in mind.”

Robbie Robinson, president of Stryker’s spine division, added: “This is an exciting time for our division, as we continue to build momentum and expand our portfolio to bring new technology to our surgeon customers. One of our goals as a medical technology company and an implant manufacturer is to complement clear visualisation and easy access with intuitive instruments and biologically inspired implant designs.

“Monterey AL combines more than 20 years of expertise in the creation of porous materials using additive manufacturing with innovative implants and instruments that are designed to give surgeons the flexibility to use our system without having to alter their preferred technique.”
