Spinal Fusion for Scoliosis

Table of Contents

Surgery Overview

In spinal fusion for scoliosis, rods, hooks, wires, or screws are attached to the curved part of the backbone and the spine is straightened. Small pieces of bone, called grafts, are then put over the spine. Bone for grafts is often taken from the person's pelvic bone. The grafts will grow together with the spinal bone, fusing it into the proper position. Spinal fusion is major surgery that usually takes several hours to complete.

Although the basic procedure is the same, a variety of specialized techniques can be used to do spinal fusion. Many different types of spinal instrumentation are used to treat scoliosis. Also, techniques vary, from what type of hooks or rods are used to whether the surgery is done from the front of the body or from the back. The method chosen will depend on a number of things, including the child's age, spinal maturity, the location and severity of the curve, the clinical opinion of the surgeon, and the preference of the child and parents.

The surgical technique most often used to straighten and stabilize the spine is to do surgery from the back, called the posterior approach.

Another option is to do the surgery from the front of the body, called the anterior approach.

What To Expect After Surgery

Antibiotics to prevent infection are usually given at the beginning of surgery and continued for 48 hours after the operation.

Most people spend several days in the hospital after surgery, gradually increasing their movement over those several days. Depending on which technique was used, some people may be fitted for a brace, but this is much less common now than in the past.

By the time a person leaves the hospital after surgery, he or she will be able to dress, bathe, feed himself or herself, and walk around. A child may not return to school for 3 to 4 weeks.

Medicine used to reduce pain will be gradually decreased over a few weeks.


After surgery, it is important to avoid any extreme bending, twisting, stooping, or lifting of objects weighing more than 10 lb (4.5 kg). One should expect to spend the first weeks at home with occasional rest periods throughout the day.

Activities that could jar the spine—including competitive sports, ice skating, roller skating, and skiing (water or snow)—are restricted for 6 to 12 months. Cycling and swimming can usually be resumed in 3 to 4 months, unless prohibited by a brace or cast.

Why It Is Done

Surgery is indicated for:

Other factors considered before surgery include:

Surgery may be considered in some situations, such as:

For very young children, the timing of surgery for severe scoliosis is controversial. Some experts believe that surgery should be delayed until the child is at least 10 years old and preferably 12 because surgery stops the growth of the part of the spine that is fused. But in some situations, early surgery can't be avoided.

How Well It Works

Whether surgery is successful depends on many factors, including the flexibility of the curve and the technique that was used.

Multiple-hook, multiple-screws (that may also include hooks), and double-rod systems improve the shape of the spine and back as seen from the back and side.

The goal of surgery is not a perfectly straight spine but a balanced one, in which fusion prevents the curve from getting worse.

After surgery, back pain in adults usually gets better or goes away.


Risks of surgery include neurological complications, infection, and lung problems.

Surgery in an adult carries a higher rate of complications and risks than in a child or teen, including blood clots, infection, and neurological complications.

Other risks of surgery

Early complications of surgery include the following:

Late complications after surgery include the following:

What To Think About

Fusing the curved area of the spine will cause that portion of the spine to stop growing. But this should not greatly affect a child's adult height, because the rest of the spine will continue to grow normally.
