Spinal Fusion

Lumbar spinal fusion is surgery to join, or fuse, two or more vertebrae in the low back.

Spinal fusion is major surgery, usually lasting several hours. There are different methods of spinal fusion.

Laminectomy is one of the most common back surgeries. During a laminectomy, a surgeon removes the rear portion of one or more spinal bones (vertebrae). Bone spurs and ligaments that are pressing on nerves may be removed at the same time. Here's what to expect before, during, and after your laminectomy.

Bone is taken from the pelvic bone or from a bone bank. The bone is used to make a bridge between vertebrae that are next to each other. This bone graft helps new bone grow.

Metal implants are usually used to hold the vertebrae together until new bone grows between them.

What To Expect After Surgery 

You will need to be watched in the hospital for a few days after surgery.

Bed rest is not usually needed while you recover at home.

Your doctor may recommend that you wear a back brace while you recover.

Rehabilitation can take a long time. It includes walking, riding a stationary bike, swimming, and similar activities.

Why It Is Done 

Spinal fusion may be done by itself or along with surgery to remove bone and tissue that are narrowing the spinal canal and squeezing the spinal cord and/or the spinal nerves.

It may be done as a follow-up after surgery that was done to treat problems such as spinal stenosis, herniated discs , injuries, infection, and tumors.

Spinal fusion was first used to treat fractures or other problems. It is now also used to treat age-related spinal problems and spinal stenosis.

How Well It Works 

Spinal fusion is often needed to keep the spine stable after injury, infection, or a tumor.

But there is not a lot of research about how well it works for other spinal problems. In general, studies do not show a clear difference between spinal fusion and intense rehabilitation for treating chronic low back pain from degenerative changes in the spine.1

As you decide about having spinal fusion, talk with your doctor about the benefits and risks. The surgery costs a lot and has serious risks. Although this type of surgery is common, there is no guarantee it will work to relieve your pain.
