Spinal Fusion (Arthrodesis)
Spinal fusion is surgery to join, or fuse, two or more vertebrae.
Spinal fusion is major surgery, usually lasting several hours. There are different methods of spinal fusion.
When you've got back pain, one of the best questions you can ask is, "Why is it happening?" That can be the first step to helping the problem. Common causes for back pain include: Muscle and ligament injuries. These are the most common causes of back pain. Shoveling snow or helping a friend move her couch can sometimes overstretch the muscles or ligaments. You can wind up with strains or sprains. Most of these injuries heal in a few days to weeks. Disc injuries...

- 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 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.
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.1
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. One study showed no clear difference between spinal fusion and intense rehabilitation for treating chronic low back pain.2
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.
Risks
The risks of this surgery depend on your age and overall health, what you're having the surgery for, and the type of procedure you have.
Risks include:
- Pain at the bone graft site.
- Failure of the fusion, breakage of metal implants, or both.
- Blood clots that may also lead to pulmonary embolism.
- Nerve injury.
- Graft rejection.
- Infection.
What To Think About
Because there are so many things to consider when spinal fusion is recommended, seek a second opinion before making a decision.
