The M6-C™ artificial cervical disc is the natural choice for helping preserve motion in patients undergoing cervical disc replacement. Designed to mimic the structure and movement of a patient’s natural vertebral disc, the M6-C disc is the only artificial disc that incorporates an artificial nucleus and woven fiber annulus. The M6-C disc offers an innovative non-fusion solution in treating degeneration of the cervical disc.
The M6-C artificial cervical disc is an innovative next-generation option for people needing spinal fusion or artificial disc replacement. This unique product is designed to mimic your spine’s natural disc’s structure and movement, including up and down, side to side, backward and forward, and rotation. In addition, the M6-C disc is the only disc designed with a gel nucleus and fiber annulus that replicates the controlled range of movement and cushioning effect of the natural disc. By allowing your spine to move naturally, the M6-C disc also minimizes the stress to spinal discs above and below the treated level and other vertebral structures.
Watch the video above to see how the M6-C disc is designed to restore natural motion and absorb shock to the spine. See why the M6-C disc is the natural choice.
The M6-C artificial cervical disc is indicated for reconstruction of the disc following single-level discectomy in skeletally mature patients with intractable degenerative cervical radiculopathy with or without spinal cord compression at one level from C3 – C7. Degenerative cervical radiculopathy is defined as arm pain and/or a neurological deficit (numbness, weakness, deep tendon reflexes changes) with or without neck pain due to disc herniation and/or osteophyte formation and confirmed by radiographic imaging (CT, MRI, x-rays).
The M6-C artificial cervical disc is implanted via an anterior approach. Patients should have failed at least 6 weeks of conservative treatment or exhibit progressive neurological symptoms which could lead to permanent impairment prior to implantation of the M6-C artificial cervical disc.
The M6-C artificial cervical disc should not be implanted in patients with the following conditions:
Advanced cervical anatomical deformity (e.g., ankylosing spondylitis, scoliosis) at the operative or adjacent levels
Symptomatic facet arthrosis defined as pain in the neck that is worse when in extension and/or rotation and/or stiffness or the inability to move part of the neck attributable to the facets as confirmed by imaging (x-ray, CT, MRI, bone scan)
Advanced degenerative changes (e.g., spondylosis) at the index vertebral level as evidenced by bridging osteophytes, excessive translation or kyphotic deformity > 11° on neutral x-rays
Active systemic infection or infection at the operative site
Osteoporosis defined as DEXA bone mineral density T-score ≤ -2.5
Known allergy to titanium stainless steel, polyurethane, polyethylene, or ethylene oxide residuals
