Lumbar Spinal Fusion

Lumbar spinal fusion is a surgical procedure that involves placing bone graft material between adjacent vertebrae to promote bone growth that joins together, or "fuses," the two structures. The graft material functions as a bridge between the vertebrae where the new bone must form for successful fusion to occur.

A lumbar fusion is performed when the spine is unstable because of a condition such as degenerative disc disease, spondylolisthesis or spinal stenosis. Spinal instability may cause pain, numbness and muscle weakness in the arms and/or legs, depending on where in the spine it occurs.

Today, lumbar fusion can be performed using a minimally invasive approach. Traditional, open spine surgery involves cutting and stripping the muscles from the spine. Minimally invasive spine surgery requires a small incision and muscle dilation, a surgical technique that allows the surgeon to separate the muscles surrounding the spine rather than cutting or stripping them.

A minimally invasive lumbar fusion procedure, such as a posterior lumber interbody fusion, posterolateral fusion, or transforaminal lumbar interbody fusion, typically leaves a small scar or scars. Post-surgical discomfort may be relieved with medication, and some patients undergoing a minimally invasive lumbar fusion are able go home the day after surgery.

To determine whether you are a candidate for minimally invasive surgery, talk to your doctor. To find a spine surgeon who performs minimally invasive spine surgery, visit our Find A Doctor locator.

It is important that you discuss the potential risks, complications, and benefits of spinal surgery with your doctor prior to receiving treatment, and that you rely on your physician's judgment. Only your doctor can determine whether you are a suitable candidate for this treatment.
