Mobi-C Cervical Disk Replacement

Mobi-C is the first and only cervical disc in the U.S. approved to treat more than one level of the cervical spine. It received FDA approval for one and two-level indications in August 2013.

Mobi-C Facts

  • 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 40,000 spinal levels in 25 countries.
  • Mobi-C entered an FDA clinical trial in 2006, in which 647 levels of Mobi-C were implanted. A total of 599 patients were involved in the clinical trial at 24 study centers across the U.S. This represents the largest clinical trial ever conducted in the U.S. for cervical disc replacement. Mobi-C received FDA approval in August of 2013, making it the first cervical disc with both one and two-level indications.
  • 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 intended for adult patients (skeletally mature) with arm pain and/or neurological symptoms (such as weakness or numbness) with or without neck pain at one or two adjacent levels from C3 – C7 in the cervical spine. Patients should have failed non-surgical care (such as physical therapy or medications) for at least 6 weeks, or shown signs of progressively worsening symptoms. Disc damage needs to be confirmed by a doctor’s review of CT, MRI, or x-ray images. A doctor should always be consulted for proper indications and use of Mobi-C.

Mobi-C – How it Works

Mobile Core

  • 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 reduce the stresses between the implant and adjacent bone, eliminating the more invasive fixation features found in other cervical disc replacement devices.

Bone Sparing

  • Mobi-C provides bone sparing fixation without chisel cuts into the small vertebral bodies of the cervical spine. Competitors’ discs achieve their fixation via keel cuts or screw holes into the bone.
  • Mobi-C was designed without a keel to minimize bone removal, applicable for both one and two-level indications. This is especially beneficial for two-level applications where integrity of the bone between the discs is important.
