Cervical Corpectomy and Strut Graft
Many cervical problems occur due to degenerative changes in the discs and joints of the neck. Unfortunately, these changes commonly take place as a natural part of aging and from the effects of daily wear and tear on the parts of the spine. Also, degenerative changes in the neck sometimes lead to a serious condition where pressure occurs on the spinal cord. Normally, doctors can relieve the pressure by removing the degenerative vertebrae and replacing them with a bone graft. Also, this refers to a procedure called a corpectomy and strut graft.

In order to understand a patient’s symptoms and treatment choices, one should understand a basic understanding of the anatomy of the neck. Additionally, this includes becoming familiar with the various parts that make up the cervical spine and how they work together.
By removing one or several vertebras by a procedure called a corpectomy, the spinal cord will see less pressure. Furthermore, Corpus means “body” and ectomy means “remove.” Removing the discs between the vertebrae also takes place.
After removal of the vertebral body (or bodies), a cervical fusion takes place. When the surgeon removes one or more vertebrae, a bone graft fills the space. As the bone graft heals, it fuses to the intact vertebrae above and below it. Then the bone graft provides structural support to the cervical spine.
In the cervical corpectomy procedure, the surgeon removes the vertebrae from the front. Then the surgeon makes an incision in the front of the neck beside the trachea (windpipe). Subsequently, the muscles are moved to the side and the arteries and nerves become protected.
Upon reaching the front of the spine, the surgeon uses an X-ray to identify the correct vertebrae and discs. The surgeon identifies the vertebral bodies and discs causing the problems and removes them all the way back to the spinal cord. Bone spurs that extend from the back of the vertebrae toward the spinal canal are removed as well. Special care reduces the risk of damaging the spinal cord and nerve roots.
Once the removal of the vertebrae and discs takes place, the space between the vertebrae above and below must get filled. Doctors typically implant a graft of bone into the void of space. In addition, the section of bone graft works like a “strut” to support the spine. The formation of the strut can take place by taking bone from your hip (pelvis) or from the fibula bone in your leg. Bone taken from your own body refers to an autograft. Your surgeon may also use allograft, which refers to bone taken from a source other than your body and stored in a bone bank.
When installing a bone graft, metal (titanium) plates and screws secure it so that it does not move or slip. Furthermore, the plate sits on the front of the remaining vertebrae, covering the strut graft. To hold the plate in place and keep the bone graft from slipping, screws are placed into the vertebral bodies above and below the graft
Like all surgical procedures, operations on the neck may generate complications. Because the surgeon operates around the spinal cord, neck operations are always considered extremely delicate and potentially dangerous. Before having this procedure, patients should take the time to fully review the risks associated with cervical spine surgery with their doctor — making sure you agree and understand the risks and the benefits of the procedure planned for your treatment.
Doctors will tell you that neck operations require a neck brace because the operations are serious and complex; therefore, requiring a brace after surgery to help heal the procedure. And some patients may need the extra support of a halo brace. On the other hand, most patients do not require rehabilitation after this surgery. However, if a patient experiences pain or difficulty doing routine activities, a short rehab under the direction of a physical therapist can certainly help
Finally, once the fusion becomes healed, the patient may progress toward a more vigorous rehabilitation program.
