RasouliSpine is the Premier Provider of the M6-C Artificial Cervical Disc

Dr. Alexandre Rasouli is the number one user in the United States of the M6-C artificial cervical disc replacement, designed to maintain the natural behavior of a functional spinal unit by replicating the biomechanical characteristics of the native disc. Unlike the ball-and-socket designed artificial discs, this design enables the disc to move in all six degrees of freedom, with independent angular rotations (flexion-extension, lateral bending and axial rotation) along with independent translational motions (anterior-posterior and lateral translations as well as axial compression). The device is intended to replicate the physiological phenomenon of progressive resistance to motion in all six degrees of freedom. The TPS coating is intended to promote bone growth onto the plates providing long- term stability of the M6-C artificial cervical disc in the disc space.


Quality of Motion assesses how well the motion of an implanted functional spine unit approximates the motion of a healthy one over the entire range of motion, not just its endpoints. Through biomechanical testing, a load vs. angular displacement curve (“kinematic signature”) is generated that allows assessment of the Quality of Motion parameters. Biomechanical testing with the M6-C artificial cervical disc has demonstrated similar Quality of Motion compared to the native disc. The innovative artificial fiber annulus and nucleus construct of the M6-C disc is the critical component in replicating this physiological motion, as it is designed to provide the necessary restraint and control needed throughout the spine’s natural range of motion.
