The Freedom® Cervical Disc (FCD) is intended to replace degenerated cervical discs. The FCD polymer core is designed to provide the kind of stiffness similar to that found in healthy human discs. The viscoelastic core of the FCD responds to different loads and loading rates the way a human spine does. The material characteristics of the polymer used in all Freedom® Discs, in combination with their design, provide both stability and three-dimensional motion that biomechanical testing has shown functions within the natural biomechanics of the spine. The Freedom® Cervical Disc is designed to withstand the forces and wear characterised by decades of use as an implant in relatively young patients.
