Understanding Neck Surgery with an Implant

In neck surgery, the damaged disc is typically removed and replaced with an implant, made of metal, plastic or bone.  The implant put in the disc space helps match the disc height to the healthy levels above and below. Restoring the disc height can help remove pressure on the nerves and/or spinal cord and help relieve your symptoms.

Cervical Disc Replacement at Two-Levels

Motion Preservation

The goals of cervical disc replacement with the Mobi-C® Cervical Disc include:

  • removing the unhealthy disc,
  • restoring a healthy disc height and
  • maintaining motion at the operated level(s).

The Mobi-C Cervical Disc has three parts: two metal plates and a plastic insert in the middle. The plates have teeth on the top and bottom that help hold the plates to the back bones (vertebrae). The insert is made to move as you move your neck. This operation is done through an incision in the front (anterior) of your neck.

Mobi-C Cervical Disc

To be used in the United States, Mobi-C went through major testing and review with the Food and Drug Administration. Five years after surgery, Mobi-C at two-levels achieved superior outcomes compared to fusion surgery.

Fusion

After a successful cervical fusion surgery, the bones of the neck grow together at the operated level stopping movement.

Anterior Cervical Discectomy and Fusion (ACDF) at two-levels

Fusion from the Front (Anterior) of the Neck

In an anterior cervical fusion, the operation is done through an incision in the front of your neck. The goals of anterior cervical fusion surgery include:

  • removing the unhealthy disc,
  • restoring a healthy disc height and
  • stopping motion at the operated level(s).

The surgeon will remove and replace your damaged disc(s) with a metal, plastic or bone implant or spacer.  In some cases, a plate with screws is also placed on front of the neck bones to provide extra stability.

Fusion from the Back (Posterior) of the Neck 

In a posterior cervical fusion, the operation is done through an incision in the back of your neck.  The goals of posterior fusion surgery include:

  • removing pieces of the unhealthy disc, when possible
  • un-pinching nerves or the spinal cord and
  • stopping motion at the operated level(s).

The surgeon will remove any side (lateral) disc herniations.  Then screws are inserted into the vertebrae above and below the damaged level(s).  A rod is used to connect the screws to prevent movement and allow healing.

Posterior cervical fusion is less common than anterior cervical fusion.  Less than one in four cervical fusion cases are done through a posterior incision.1
