Cervical Disc Replacement

What is the Mobi-C Cervical Disc?

The Mobi-C Cervical Disc is an artificial cervical disc implant composed of three pieces: two end plates and a plastic insert.

The Mobi-C Cervical Disc is the global leader in cervical disc arthroplasty.1 Since 2004, over 200,000 Mobi-C Discs have been implanted across 25 countries.

Mobi-C Cervical Disc was the first cervical disc in the U.S. approved to treat more than one level of the cervical spine, and Mobi-C is a proven cervical disc with 10-years of clinical data showing improved long-term outcomes for one and two-level replacements.

At 10 years, all patient-reported outcomes of Mobi-C recipients were equivalent to or improved from 7 years. Recipients of Mobi-C reported improved Neck Disability Index (NDI) Scores, improved neck pain, and improved arm pain. In addition, no subsequent surgery at an adjacent level occurred between the 7-year and 10-year follow up.

Mobi-C Cervical Disc Compared to Fusion

Before artificial discs were approved for use, most often a patient would get an anterior cervical discectomy and fusion (ACDF). In this fusion surgery, the surgeon removes the unhealthy disc. The empty disc space is filled with a bone spacer or plastic implant. The implant helps match the disc height to the levels above and below. Restoring the disc height can help remove pressure on the nerves and/or spinal cord. Then, a metal plate with screws is placed on the front of the neck. The plate helps keep the spacer in place and stop movement at the level or levels it spans. This helps new bone grow between the vertebrae (fusion).

However,studies have shown cervical disc replacement to have benefits over fusion. 1,2

In a surgery with the Mobi-C Cervical Disc, the unhealthy disc is removed, but instead of a bone spacer or plastic implant along with a plate and screws, a Mobi-C is implanted into the disc space. Where a fusion procedure is intended to eliminate motion at the surgery levels, the goal of a surgery with Mobi-C is to allow motion at those levels.

Both fusion and Mobi-C artificial disc surgery:

  • Replace the damaged disc.
  • Try to match a healthy disc height to help un-trap any nerves.

Unlike fusion the Mobi-C implant is:

  • Designed to maintain neck movement and adapt to the motion in your spine.

 

The Mobi-C Cervical Disc is an artificial implant used in cervical disc arthroplasty. It consists of two end plates and a plastic insert. It is considered a leading solution globally and has been implanted in over 200,000 patients across 25 countries since 2004.

 

One notable feature of the Mobi-C Cervical Disc is its approval for treating multiple levels of the cervical spine, making it the first of its kind in the United States. It has a proven track record with 10 years of clinical data, demonstrating improved long-term outcomes for both single and double-level replacements.

 

Studies have shown that patients who received the Mobi-C implant experienced equivalent or improved outcomes compared to the seven-year mark. These outcomes include better Neck Disability Index (NDI) scores, reduced neck pain, and improved arm pain. Additionally, there were no instances of subsequent surgery at adjacent levels during the follow-up period between seven and ten years.

 

In contrast to the traditional fusion surgery known as anterior cervical discectomy and fusion (ACDF), which involves removing the damaged disc and filling the empty space with a bone spacer or plastic implant, the Mobi-C Cervical Disc offers distinct advantages. The Mobi-C implant allows for preservation of motion at the surgery levels, while fusion aims to eliminate motion.

 

Both fusion and Mobi-C artificial disc surgeries aim to replace the damaged disc and restore healthy disc height to relieve nerve pressure. However, the Mobi-C implant is specifically designed to maintain neck movement and adapt to the natural motion of the spine, distinguishing it from fusion procedures.
