Lumbar Spinal Fusion Surgery

One of the most widely used types of spinal surgeries is lumbar spinal fusion. This procedure involves surgically fusing two or more vertebrae together. This treatment is typically performed on patients who suffer from lumbar fractures, degenerative disc disease (DDS), or spinal instability. This surgery often includes additional procedures to help relieve pressure on nerves and other areas of the spine.

What Areas of the Lower Back and Spine Will Receive Treatment?

Undergoing a lumbar spinal fusion will involve several important areas of your lower back and spine. Surgeons typically reach the affected region in your lower back by making an incision that allows access to the bony points of your vertebrae. The muscles along the side of your spine will be moved aside so that your surgeon can reach the lamina bone, which protects the spinal cord surface.

Understanding Anterior vs. Posterior Lumbar Fusion

There are a few different surgical approaches your doctor will choose between depending on the condition of your spine and the type of fusion needed to correct your spinal issues.

Posterior Surgical Method

This particular surgical method is useful for any region of the spinal column needing fusion of vertebrae. Posterior lumbar fusion will require an incision that goes through the back. Once the surgeon has inserted any needed screws or rods, removal of the top bone layer occurs so that graft material can be used to encourage growth and fusion.

Anterior Surgical Method

Patients that need additional stability could undergo an anterior surgical method, which involves reaching the spine through an incision in the front of the body. Once your surgeon has access to your spine, the replacement of affected vertebral discs between the impacted vertebrae can take place. After this removal, a specially designed cage will be placed around the empty disc area to hold bone grafting material linking the surrounding vertebrae together.

Anterior/Posterior Fusion Method

For individuals needing stability on the front and back of their spine, an anterior/posterior fusion method may be the best option to ensure the best possible stability.

Patients may need this procedure if they have:

• Suffered a fracture
• A high degree of DDS
• Excessive spondylosis, or an abnormally curved spine

One can also expect any bone spurs to be removed, as well as discs that may need replacement.
