What Conditions Can Mobi-C Treat?

The cervical spine has discs between each bone that provide cushioning for movements and body loads.  The discs and bones in a healthy neck allow bending from side-to-side and front-to-back, and turning left-to-right.  Disc problems can start from over-use, an accident, or just the wear and tear of daily life.  Degenerative changes in the discs may result in damage that can cause pain.  When a disc degenerates it can have tears or cracks that lose water, which cause it to become thinner and provide less padding to absorb movement.  Degenerated discs can also bulge (herniate) and pinch the spinal cord or nerves, which causes loss of feeling, weakness, pain, or tingling down the arms and hands.

Treatment Options

Anterior Cervical Discectomy and Fusion ( ACDF)

Before artificial discs were available, patients would traditionally receive an Anterior Cervical Discectomy and Fusion (ACDF) procedure to alleviate the pain from a herniated disc.  In a fusion surgery, the disc is removed and either a bone spacer or a plastic implant will be placed in the disc space to restore disc height and remove pressure on the pinched nerves or spinal cord.   A metal plate and screws can be placed on the front of the neck to hold the implant in place.  The result of this procedure will be a segment that no longer moves, or is “fused”.  The potential downside of a fusion procedure, in addition to the loss of motion, is that it can create additional stress on the spinal levels above and below it.  This can cause degeneration at those levels and potentially result in another future surgery.


An artificial disc like Mobi-C is an option instead of a fusion that will also be placed inside the disc space to restore height and remove pressure on the pinched nerves.  However, the Mobi-C device is designed to allow the neck to maintain normal motion and potentially prevent the adjacent levels from degenerating, possibly preventing future surgeries.

What is Mobi-C?

The Mobi-C Cervical Disc is one of the most widely used cervical discs in the world.  First implanted in France in November 2004, Mobi-C has now been implanted in more than 75,000 spinal levels in 25 countries. Mobi-C is made with two Cobalt Chromium alloy endplates that are plasma sprayed with titanium and coated with hydroxyapatite, and has an Ultra High Molecular Weight Polyethylene plastic insert (UHMWPE).  These are proven materials that have been used in orthopedic applications for over 60 years.

  • Mobi-C is designed to replicate the natural motion of the cervical spine.
  • Mobi-C’s mobile core slides and rotates inside the disc, self-adjusting to the patient’s cervical spine’s movements.  This means that Mobi-C can react to the normal motion in the cervical spine.
  • In addition, the mobile core is designed to allow for some movement, reducing the forces between the implant and vertebral bodies.  The Mobi-C does not need invasive fixation features found in some cervical disc replacement devices.


What are the Benefits of Mobi-C?

Mobi-C is differentiated from other cervical discs because of its bone sparing technique, which eliminates the need for bone chiseling and drilling, lending to two-level implantations due to its minimal bone removal.

The greatest clinical benefit of cervical disc replacement with Mobi-C compared to cervical fusion was seen in two-level indications, particularly in lower reoperation rates, lower rates of major complications, lower rates of adjacent level degeneration, and higher NDI success rates. In the Mobi-C clinical study, patients returned to work on average approximately one week faster (one-level patients) and three weeks faster (two-level patients) compared to fusion patients.
