What Is Spinal Fusion Surgery?

Doctors do spinal fusion surgery to help kids and teens with scoliosis or other spine problems.

It's called "fusion" because the surgery lets two or more bones in the spine (called vertebrae) fuse (grow together) into one solid bone. This helps the spine grow in a straighter position and sometimes eases back pain.

Why Is Spinal Fusion Surgery Done?

Many kids with scoliosis don't need medical treatment. Others will wear a brace to keep the spine from developing more of a curve.

But some kids have scoliosis that's too severe to be helped by a brace or are too old for bracing. Others may have a type of scoliosis or other spine condition where bracing isn't helpful. These kids may need a spinal fusion to straighten the curve as much as possible and stop it from getting worse.

What Happens During Spinal Fusion Surgery?

Kids and teens having a spinal fusion will be given general anesthesia. This lets them sleep through the operation, which takes several hours.

• After making an incision (cut) in the back, the surgeon makes cuts in the bone to put it in a straighter position.
• Then, the surgeon puts in rods and screws to hold the bone in that straighter position. The metal parts are placed deep under the spine muscles. In most cases they can't be felt and don't hurt.
• Finally, the surgeon packs in bone graft (small pieces of bone) where the rods and screws are. This will eventually fuse the spine bones together.

What Happens After Spinal Fusion Surgery?

After a fusion, most kids stay in the hospital for a couple of days while they recover from surgery and increase their movement. By the time they go home, they'll be able to walk around and do many day-to-day things (shower, dress themselves, and climb stairs).

Kids whose scoliosis is very severe or who have other medical conditions might need a longer hospital stay. Their care team will watch for and treat any complications (such as pneumonia, constipation, or trouble eating).

Most kids take prescription medicines regularly for less than 2 weeks to help them deal with pain and muscle spasms. Over time, they can take less pain medicine. Sometimes, kids can switch to acetaminophen or ibuprofen if the health care provider says it's OK.

How Can I Help My Child?

To help your child recover at home:

• Encourage your child to walk or move around a little bit more each day. Start with light activity around the house, like going to get the mail or letting the dog out. Soon your child will be able to get out of the house to do normal, everyday activities like walking around the mall or going out to eat.
• Make sure your child doesn't drive or lift more than a few pounds until the health care provider says it's OK.

Your health care provider also will let you know when your child can go back to school. Most kids return about 3–4 weeks after the surgery, but can't go to gym class or play sports for a while (usually 2–6 months) because the bones are still fusing. Let the school staff know your child will need help at first, such as extra time to get through the hallways or a second set of schoolbooks to keep at home.

Sometimes kids will need physical therapy to complete their recovery. This usually starts about 4–6 weeks after surgery, and can continue for several months.

Looking Ahead

After about 6 months to a year, the bones should be fully fused. Although the metal rods are no longer needed, they are left in the patient's back because they aren't doing any harm and taking them out would involve another operation.

After a full recovery, kids can play sports again and do all the activities that they enjoyed doing before surgery.
