M-6 Cervical
The M6 Artificial Disc is designed to replicate the anatomic structure and biomechanical performance of a natural disc. Its innovative design incorporates an artificial nucleus to allow axial compression and a woven fiber annulus for controlled range of motion in all 6 degrees of freedom.
Nucleus
• Viscoelastic polymer designed to simulate native nucleus
• Allows physiologic axial compression
• Retained between endplates & fiber annulus matrix
• Designed to enable physiologic Center Of Rotation
Annulus
• Ultra High Molecular Polyethylene (UHWMPE) fiber material
• Intended to simulate native annulus & its performance
• Designed to provide controlled physiologic motion in all planes and axes
• Robust fiber matrix with multiple layers similar to native annulus
Sheath
• Designed to minimize tissue in-growth & debris migration
• Allows for full range of motion
Fixation
• Titanium endplates with tri-keel design
• Titanium Plasma Spray (TPS) coated endplate
• Low profile keel height (2mm)Biomechanical testing with the M6 artificial cervical disc has demonstrated equivalent Quality of Motion compared to the healthy disc. The innovative artificial fiber annulus and nucleus construct of the M6 is the critical component in replicating this physiologic motion, as it is designed to provide the necessary restraint and control needed throughout the spine's natural range of motion.
