Cervical Interbody Fusion

CSC Offers Modern Approach to Cervical Fusions for Neck Pain Relief

CSC uses a variety of innovative technologies to perform modern cervical spine fusions.

Fusion is the bonding together of bones, usually with the aid of bone graft or a biological substance. A fusion stops motion between 2 vertebrae and provides long-term stabilization. It is very similar to natural fracture healing.

In a cervical fusion, adjacent vertebral bodies, facets, and/or the lamina may be fused together.

If the fusion is done from behind (posterior), the surgeon typically will lay strips of bone graft from one lamina, or lateral (side) mass to the lamina, or lateral mass below. Usually, bone graft will fuse across these structures over time and stabilize the two vertebrae. The surgeon may use a similar technique to fuse the facet joints together, too.

Anterior cervical fusion is an operation performed on the upper spine to relieve pressure on one or more nerve roots, or on the spinal cord. The term is derived from the words anterior (front), cervical (neck), and fusion (joining the vertebrae with a bone graft).

Why Is It Done?

When an intervertebral disc ruptures in the cervical spine, it puts pressure on one or more nerve roots (often called nerve root compression) or on the spinal cord, causing pain and other symptoms in the neck, arms, and even legs. In this operation, the surgeon reaches the cervical spine through a small incision in the front of the neck. After the muscles of the spine are spread, the intervertebral disc is removed and a bone graft is placed between the two vertebral bodies. Over time, this bone graft will create a fusion between the vertebrae it lies between.

In more than 90 percent of cervical spine fusion surgeries done in the United States today a small cervical plate is used to stabilize the spine immediately after surgery. This hardware is used to improve the stability of the spine immediately after surgery and to also decrease the chance that the bone graft might be dislodged or moved slightly from the position that it was placed in by the surgeon. The use of hardware for stabilizing the cervical spine has changed the way in which cervical collars are used after surgery. Today, collars are typically worn for a shorter period of time after surgery than in the past.

What Happens Afterwards?

Successful recovery from anterior cervical fusion requires that you approach the operation and recovery period with confidence based on a thorough understanding of the process. Your surgeon has the training and expertise to correct physical defects by performing the operation; he or she and the rest of the health care team will support your recovery. Your body is able to heal the involved muscle, nerve, and bone tissues. Full recovery, however, will also depend on you having a strong, positive attitude, setting small goals for improvement, and working steadily to accomplish each goal.

Incision

Surgery for anterior cervical fusion is performed with the patient lying on his or her back. A small incision is made in the front of the neck, to one side.

After a retractor is used to pull aside fat and muscle, the disc is exposed between the vertebrae. Part of it is removed with a forceps.

Then a surgical drill is used to enlarge the disc space, making it easier for the surgeon to empty the intervertebral space fully and remove any bone spurs. Afterwards, only a single ligament separates the surgical instruments from the spinal cord and nerve roots.anteriorcervicaldisc7

Placement of the Bone Graft

A small section of bone is obtained from the patient’s iliac crest (i.e. hip), through a separate incision and used as a bone graft. The bone graft is placed in the disc space, where it will begin to fuse the vertebrae it lies between.

anteriorcervicaldisc9Placing a bone graft between the two vertebral bodies is done in order to create a fusion between these bones. The fusion is a direct result of the bone graft, but small, specialized metal plates are also placed on the front of the cervical spine in order to increase the stability of the spine immediately after the operation. Surgeons use cervical hardware to decrease the amount of time that you will have to wear a collar after surgery, and also to increase your chances of getting a solid fusion between the two vertebral bodies.

Incision Closure 

The operation is completed when the neck incision is closed in several layers. Unless dissolving suture material is used, the skin sutures (stitches) or staples will have to be removed after the incision has healed.

Stem Cell
Therapy

Center for Spine Care offers stem cell therapy as a conservative treatment to promote natural healing for back or neck pain. Utilizing mesenchymal stem cells, this new method is used to treat patients with neck and back pain caused from degenerative disc disease.
