Anterior Lumbar Fusion

Lumbar Spine

Anterior lumbar fusion is a surgical procedure performed to alleviate persistent lumbar pain (pain in the lower region of the back) by joining two or more vertebrae with bone grafts. This fusion eliminates the mechanical motion that results in inflammation and pain. Anterior lumbar fusion is performed from the front of the spine through the abdomen. Reasons for performing the procedure from the front of the body include instability of the spine, degenerative disc disease or fracture. During the anterior procedure, the back muscles and nerves are not disturbed. Also, the anterior approach places the spine in compression which is an advantage when trying to establish bone fusion.

Reasons for Anterior Lumbar Fusion

This operation may be performed for any of the following reasons:

  • Disc degeneration
  • Scoliosis or kyphosis
  • Vertebral fracture
  • Spondylolisthesis
  • Spinal stenosis
  • Spinal instability

Anterior lumbar fusion is only considered when persistent low back pain, often accompanied by radicular pain (pain that radiates down the buttock and thigh), does not respond to more conservative treatments.

The Anterior Lumbar Fusion Procedure

There are often two surgeons involved in this procedure, one neurosurgeon and one general or vascular surgeon. This is because, in addition to the surgical procedure involving the spinal column itself, there is surgical work to be done on the abdomen and possibly on the peritoneum (the large sack that holds the abdominal contents). Moreover, the large blood vessels in the area, the aorta and vena cava, must be retracted during the operation.

Once there is access to the spinal cord, disc tissue is shaved away to remove any spurs or irregularities and to prepare for the bone graft. The newly cut disc is receptive to the graft and the fusion that will now take place. The bone graft may come from the patient's own hip (autograft) from a cadaver (allograft), or be manufactured from artificial materials. The procedure may be performed with one small incision or, with the help of an endoscope, through several one-inch cuts. Surgical hardware is used to the bone graft in place as the fusion takes place.

Recovery from an Anterior Lumbar Fusion

The recovery period after an anterior lumbar fusion is variable, but usually takes a minimum of 3 months. Patients are advised to avoid bending, twisting and heavy lifting during this period to allow the bone graft time to create a permanent fusion. After the bone is fully healed, physical rehabilitation is usually necessary to re-establish muscle strength and flexibility.
