ALIF: Anterior Lumbar Interbody Fusion

Anterior lumbar interbody fusion (ALIF) is most often recommended for back or leg pain that comes from degenerative disc disease. The goal is to make the spine stable by joining vertebrae together with bone graft.

The Incision

The surgeon reaches the spine from the front, through an incision of about three to five inches in the abdomen. It is usually made either down the middle of the stomach or a little off to one side.

Removing the Disc

Most of the worn disc is taken out. Part of its outer wall is intentionally left in place so it can help hold the bone graft.

Placing the Implant

A metal cage packed with bone graft goes into the space where the disc was. It brings the vertebrae back into line and takes pressure off pinched nerve roots.

Securing the Vertebrae

For some patients the cage alone holds the vertebrae steady. Others need extra support, so the surgeon adds screws and rods along the back of the spine.

After Surgery

In the months that follow, bone grows into and around the implant and links the vertebra above with the one below. That solid bridge of bone is the fusion.
