Surgical Treatment for Scoliosis
Common Questions About Surgery for Scoliosis

Most scoliosis surgeons agree that children who have very severe curves (45-50° and higher) will need surgery to lessen the curve and prevent it from getting worse.

The operation for scoliosis is a spinal fusion. The basic idea is to realign and fuse together the curved vertebrae so that they heal into a single, solid bone.

With the tools and technology available today, scoliosis surgeons are able to improve curves significantly.

Do I need surgery?

If your curve is greater than 45-50°, it will very likely get worse, even after you are fully grown. This may increase the cosmetic deformity in your back, as well as affect your lung function. Surgery is recommended.

Curves between 40° and 50° in a growing child fall into a grey area — several factors may influence whether surgery is recommended. These should be discussed with your surgeon.

How successful is surgery for scoliosis?

Spinal fusion is very successful in stopping the curve from growing. Today, doctors are also able to straighten the curve significantly, which improves the patient's appearance.

How straight will my spine be after surgery?

Because your spinal bones protect your spinal cord, your surgeon will straighten the bones only as far as is safe.

The degree of correction from surgery depends on how flexible your scoliosis is before your operation. In general, the more flexible your curve is, the better the correction from surgery. Your doctor can measure your flexibility before surgery with special x-rays called bending or traction films.

Most patients recover from surgery with curves that have been straightened to less than 25°. In many cases, these small curves are hardly noticeable.

I have back pain associated with my scoliosis. Will the surgery relieve it?

Immediately after surgery, there will be more pain than before, but this usually resolves over a period of a few weeks to a few months. Most patients report that their back pain is better at 1 year from surgery than it was beforehand.

Everyone — whether there is scoliosis or not — has some back discomfort from time to time. Expecting to never have any future back pain would be unrealistic.

What is involved with a spinal fusion surgery?

In a spinal fusion, the curved vertebrae are fused together so that they heal into a single, solid bone. This will stop growth completely in the abnormal segment of the spine and prevent the curve from getting worse.

All spinal fusions use some type of bone material, called a bone graft, to help promote the fusion. Generally, small pieces of bone are placed into the spaces between the vertebrae to be fused. The bone grows together — similar to when a broken bone heals.

Metal rods are typically used to hold the spine in place until fusion happens. The rods are attached to the spine by screws, hooks, and/or wires.

Exactly how much of the spine is fused depends upon your curve(s).

What is a bone graft?

A bone graft is primarily used to stimulate bone healing. It increases bone production and helps the vertebrae heal together into a solid bone.

In the past, a bone graft harvested from the patient's hip was the only option for fusing the vertebrae. This type of graft is called an autograft. Harvesting a bone graft may require an additional incision during the operation. It increases the length of surgery and can cause increased pain after the operation because of an additional region of the pelvis being included in the procedure.

One alternative to harvesting a bone graft is an allograft, which is cadaver bone. An allograft is typically acquired through a bone bank.

Today, several artificial bone graft materials have also been developed.

How long does the surgery take?

Most fusions last from 4 to 8 hours, depending on the size of the patient's curve and how much of the spine needs to be fused.

How much pain will I be in after surgery?

The amount of pain people report after surgery varies a great deal from patient to patient. The surgery is a major procedure that involves moving muscles and realigning the skeleton.

The first few days are usually quite uncomfortable, but most people improve rapidly by the third or fourth day, and they can walk around, and get in and out of bed well enough to go home. The pain continues to improve gradually and most teenagers can return to school by 2 to 4 weeks after surgery.

Mild pain may persist, but by 3 to 6 weeks after surgery, pain medicine should no longer be necessary.

What type of pain control will there be after the operation?

Pain control varies between different doctors and hospitals. In many cases, a PCA (patient controlled anesthesia machine) is used, which injects a small dose of pain medicine intravenously when you push a button. Some surgeons use an intravenous catheter (small plastic tube placed in a vein) to provide the medication in larger but less frequent doses. The pain relief system that your doctor is accustomed to using is probably the safest and most reliable for you after surgery.

On the second or third day after surgery, your doctor will most likely change your medication to pills or liquid pain relievers taken by mouth. These medicines are an opiate (morphine-like medicine.) Because these medications are known to be addictive if taken for a long time, you will be encouraged to switch to acetaminaphen as soon as possible after you go home.

Do the rods and other implants stay in my spine even after it has fused?

If rods are used in a fusion, they usually do not need to be removed. Very few people require rod removal, and this may be for a variety of reasons such as infection or broken rod.

Will fusion make my back stiff and unable to move?

The fused portion of your back will be permanently stiff. Most people have enough motion in the unfused portion of their backs to perform all activities of daily living and most sports. If you participate in activities that require a tremendous amount of flexibility, it may take awhile to adapt. Most people find that within a year or so their backs begin to feel "normal" when participating in those activities.

Can I have my scoliosis corrected without a fusion?

We wish that we had a method and materials that would straighten the spine and also allow normal motion between all the bones. Unfortunately, we do not have this capability. Anything we put in to hold the spine straight, also makes the spine stiff in the area of surgery.

Common Questions About Surgical Recovery

Most patients are in the hospital for 4 to 7 days, out of school for 2 to 4 weeks, and back into activities in 2 to 6 months.

How long do patients need pain medication after being discharged home?

Most surgeons prescribe strong pain medicines to patients after scoliosis surgery. Patients who have not used opiate pain killers before usually stop needing them within 2 to 4 weeks after surgery. If the patient has used these medicines frequently before surgery, it may take longer to stop needing them.

It is best to stop taking these strong medicines as soon as possible because they can be addictive if taken for long periods of time.

What limitations will I have right after surgery?

Your surgeon will detail any limitations you have after surgery. Most patients will be asked to avoid heavy lifting and to minimize the amount of bending forward for the first 6 to 12 weeks.

Does surgery lead to permanent restrictions on activities?

No, most patients are able to return to all their favorite activities and sports.

Most patients return to non-contact sporting activities (running, weightlifting, exercises) approximately 4 to 6 months after surgery.

Before returning to all activities, including contact sports, the spine must be fully healed. It typically takes 6 to 12 months after surgery to obtain a solid fusion of the spine and get back to all activities.

Will I be able to walk after surgery?

Yes. Some patients may need physical therapy after surgery, but they are able to walk when they are discharged from the hospital.

When can I go back to school after the operation?

Most children miss between 2 to 4 weeks of school after surgery. It typically takes about 4 weeks before the spine is healed enough for carrying a backpack.

When will I be allowed to drive a car?

You will not be able to drive a car until you have healed well enough from surgery. In addition to being off of your narcotic pain medicines, you need to be moving around well enough to be safe. This typically takes 6 or more weeks.

When can I start hanging out with my friends again?

Your friends can visit you after surgery in the hospital and at home. Going out with your friends — like to school functions or the movies — can occur after you are off all pain medications and are feeling back to normal (this usually happens about 4 weeks after surgery).
