FLX implants include a solid exoskeleton for added strength, along with a proprietary lattice scaffold designed to have a stiffness similar to bone. Reduced device stiffness is known to minimize stress-shielding and enhance the fusion process.
FLX implants include porous radiolucent sections with optimized density to reduce imaging artifacts—enhancing intra-operative visualization & post-operative fusion assessment compared to solid titanium implants.
FLX implants include a FUSE-THRU™ osteoconductive trabecular scaffold, bioengineered to allow the potential for bony on-growth and in-growth throughout the implant. This unique porous structure contains micro, macro, and nano structural characteristics designed to promote the fusion healing process by influencing cellular events related to the production of new bone.
Proven STALIF Design
is built upon the simple, elegant design and proven success of the
The integrated cage and screw system of STALIF C FLX is cleared for use without supplemental fixation, while the "No Profile" design
allows it to nest fully within the confines of the vertebral body—leaving the anatomy unchanged external to the interbody.
Compressive lag fixation ensures biomechanical stability and provides secure graft-endplate contact. Lag screws reduce the vertebral bodies onto the cage creating graft / endplate surface compression to provide the best opportunity for fusion.
The STALIF C FLX device is engineered to achieve equivalent biomechanical performance to anterior plate & cage technologies.1

Anti Back-Out® Screws
STALIF C FLX screws provide an added layer of security with an Anti Back-Out® (ABO®) titanium split-ring
which first compresses and then deploys during insertion.
Large Graft Area
The implant is designed with a large, open, concave graft containment cavity to maximize the volume of bone graft (allograft and/or autograft) material to better promote fusion.
Multiple Heights & Footprints
The STALIF CFLX Interbody system consists of varying heights and footprint options to accommodate individual pathology and anatomical conditions.
