Cervical Artificial Disc

Mobi-C is the first and only cervical disc in the United States approved to treat more than one level of the cervical spine. This is because of a unique mobile bearing core that eliminates the need for invasive bone keels and optimizes it for two-level applications. Its patented Mobile Core Technology™ allows flexion and extension lateral bending coupled with translation similar to natural cervical motion

ANATOMY AND PATHOLOGY OF THE NECK

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 as well as turning left-to-right.

Disc problems can start from overuse, 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.

MOBI-C ARTIFICIAL DISC VS. TRADITIONAL FUSION

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.

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.

HOW IT WORKS

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.

Mobi-C provides bone sparing fixation without cuts into the small vertebral bodies of the cervical spine. It was also 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.
