Understanding Minimally Invasive Scoliosis Surgery (Child)

Minimally invasive scoliosis surgery is a type of surgery done to fix an abnormal curve of the spine known as scoliosis. Minimally invasive surgery uses 2 or more small cuts (incisions) instead of a single large incision. This may lead to less pain after surgery, and faster recovery. Minimally invasive scoliosis surgery is not available at all hospitals or other places that do surgery.

What is scoliosis?

The spine has some normal curves forward and backward. But it should not curve to the side. With scoliosis, the spine curves to the side in an S-shape or a C-shape. If the curve is severe, it can cause uneven shoulders. Your child’s body can appear to tilt to one side.

Why is minimally invasive scoliosis surgery done?

Your child may need surgery if his or her spine has a severe curve. This is a curve of at least 40° or a curve that is worsening. Or your child may need surgery in the future if other treatments, such as bracing, don’t keep the curve from getting worse. Children who have only mild curves are not likely to need surgery. Your child’s doctor will keep track of your child’s spine as he or she grows. Surgery is the only treatment that can make the spine straight. It can correct posture. It can also reduce or relieve pain.

Minimally invasive scoliosis surgery can cause less harm to back muscles and other nearby tissues. It also uses smaller incisions. This can lead to less pain and a shorter recovery pain after surgery. Your child may not be able to have minimally invasive scoliosis surgery if his or her curve is very severe.

How minimally invasive scoliosis surgery is done

The surgery is done by an orthopedic surgeon with a trained medical team. The surgeon will use a special type of X-ray to view the surgery. The doctor will make a small incision on your child’s back in the area that needs to be treated. He or she will put a tubular retractor into this incision. This will expose the part of the spine to be treated. The surgeon will then pass small tools through this retractor. This includes a tiny camera and a light. The doctor will partly straighten the spine. This is done using screws, rods, and wires. The surgeon may use a bone graft to complete the repair. Bone is used from your child’s hip or from a donor.

Risks of minimally invasive scoliosis surgery

Every surgery has risks. Risks of minimally invasive scoliosis surgery include:

  • Infection

  • Excess bleeding

  • Pain at the graft site

  • Nerve damage

  • Blood clots

  • Not enough bone formation

  • Need for a repeat surgery

Your child's risks may differ depending on his or her age, general health, shape of the curve, and the surgery method. Having the surgery at a place that is experienced in the method can help lower your child's risks. Talk with your child's doctor about the risks that most apply to your child.
