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.

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.
