A spinal fusion surgery is designed to stop the motion at a painful vertebral segment, which in turn should decrease pain generated from the joint. There are many approaches to lumbar spinal fusion surgery, and all involve adding bone graft to an area of the spine to set up a biological response that causes the bone graft to grow between the two vertebral elements and create a fusion, thereby stopping the motion at that segment.

For patients with the following conditions, if abnormal and excessive motion at a vertebral segment results in severe pain and inability to function, a fusion may be considered :

Degenerative disc disease

Isthmic, degenerative or postlaminectomy spondylolisthesis.

Other conditions that may be treated by a spinal fusion surgery include a weak or unstable spine (caused by infections or tumors), fractures, scoliosis or deformity.

How spine fusion surgery works

At each level in the spine, there is a disc space in the front and paired facet joints in the back. Working together, these structures define a motion segment and permit multiple degrees of motion. Two vertebral segments need to be fused together to stop the motion at one segment, so that an L4-L5 (lumbar segment 4 and lumbar segment 5) spinal fusion is actually a one-level spinal fusion.

Bone Grafts

A spine fusion surgery involves using bone graft to cause two vertebral bodies to grow together into one long bone. Bone graft can be taken from the patient’s hip (autograft bone) during the spine fusion surgery, harvested from cadaver bone (allograft bone). or manufactured (synthetic bone graft substitute).

In general, a lumbar spinal fusion surgery is most effective for those conditions involving only one vertebral segment. Most patients will not notice any limitation in motion after a one-level spine fusion. Only in rare cases should a three (or more) level fusion surgery for pain alone be considered, although it may be necessary in cases of scoliosis and lumbar deformity.

When necessary, fusing two segments of the spine may be a reasonable option for treatment of pain. However, spinal fusion of more than two segments is unlikely to provide pain relief because it removes too much of the normal motion in the lower back and places too much stress across the remaining joints.

There are several types of spinal fusion surgery options, including:

Posterolateral gutter fusion—the procedure is done through the back

Posterior lumbar interbody fusion (PLIF/TLIF))—the procedure is done from the back and includes removing the disc between two vertebrae and inserting bone into the space created between the two vertebral bodies

Anterior lumbar interbody fusion (ALIF)—the procedure is done from the front and includes removing the disc between two vertebrae and inserting bone into the space created between the two vertebral bodies

Anterior/posterior spinal fusion—the procedure is done from the front and the back

It is important to note that with any type of spine fusion surgery, there is a risk of clinical failure (meaning that the patient’s pain does not go away) despite achieving a successful fusion. Obtaining a successful result from a spine fusion requires and accurate preoperative diagnosis, a technologically adept surgeon, and a patient with a reasonably healthy lifestyle (non smoker, non obese) who is motivated to pursue rehabilitation and restoration of their function.
