Kyphosis
What is kyphosis?
Kyphosis (kye-FOE-sis) is the forward curve in the middle of the spine, near the ribs. Everyone has this curve. Usually, this part of the spine curves slightly, giving the back a gently rounded look. The typical range for the curve is 20 degrees to 50 degrees.
Doctors use the term kyphosis for curves that are larger than usual. You may also hear doctors call this “hyperkyphosis.”
Kyphosis is much less common than scoliosis.
Types of Kyphosis
Hyperkyphosis
Hyperkyphosis is a roundness or a hump in the middle of the back that is greater than normal.
Many teenagers slouch and look like they might have a hump. But this is not hyperkyphosis. If you ask them to stand up straight, the hump may disappear. Some doctors call this slouching “postural roundback.” Slouching often worries parents. But it has not been shown to cause any lasting change in the shape of the back.
Scheuermann kyphosis
In some rare cases, the bones of the back (vertebrae) do not grow correctly. In Scheuermann kyphosis, the front of the vertebrae does not grow as well as the back.
As your child approaches their teens, their spine grows fast. During this time, the vertebrae’s uneven growth can quickly change the shape of their back. Their back may become more curved and humped, which may cause pain.
Exercises or a back brace help some children with Scheuermann kyphosis, but most do not need any treatment. The curve is rarely big enough for doctors to recommend surgery.
Congenital kyphosis
Babies can be born with kyphosis. When the condition is present at birth (congenital), the bones in the back are shaped like wedges. Normally, these bones have a block shape. The wedge shape may cause the spine to bend sharply.
In serious cases, the sharp bend in the spine can press on the and the legs. Young children or babies with congenital scoliosis have a higher risk of spinal cord problems.
“Being at Seattle Children’s brought us a sense of comfort. I felt like they cared about us, not just as patients, but as people.”
— Magi, whose son Ryder had spine surgery at Seattle Children’s for a rare type of kyphosis that affects the neck
What are the symptoms of kyphosis?
In children as well as adults, kyphosis can cause a humped back. Other signs of kyphosis include:
- Back pain
- Intense tiredness (fatigue)
- Stiffness in the back
In more serious cases, kyphosis can cause problems in the heart and lungs. It may make your child more likely to get later in their back.
Spine Program at Seattle Children's
How is kyphosis diagnosed?
During your child’s visit to our clinic, we take of their spine to look for the cause of kyphosis. X-rays also help us find out what type of kyphosis your child may have.
If your child has congenital kyphosis, we usually ask them to have an . This helps us make sure the curve is not pressing on the spinal cord.
As your child grows, we will take X-rays of their spine every 6 months so we can check for changes. We take great care to use the lowest amount of radiation (PDF) we can to make the best image. We also will check your child’s function and development.
How is kyphosis treated?
At Seattle Children’s, we use both surgical and nonsurgical treatment for kyphosis. We have treated hundreds of children with this condition.
Exercises for kyphosis
In mild cases of Scheuermann kyphosis, doctors may recommend exercises to strengthen the back. This can relieve the pain and tiredness that sometimes happen when children are active. Studies have not shown that exercises affect the growth or development of the spine, though.
Back braces for kyphosis
If your child is still growing and has mild Scheuermann kyphosis, a back brace may stop the curve from getting worse. Our experienced team makes braces for children of all sizes and ages. Read about braces and our other orthotics and prosthetics services.
Surgery for kyphosis
If your child has pain from more severe kyphosis and physical therapy or bracing doesn’t help, we offer surgery.
-
Surgery to correct the curve and make the spine stable
In this surgery, the doctor will:
- Anchor screws or hooks to the bones in your child’s spine (vertebrae)
- Attach the screws or hooks to a metal rod and straighten the back
- Remove the between the bones
- Place a next to the spine to help the bones grow together (spinal fusion)
-
Thoracoscopic surgery
In severe cases, we use (thoracoscopic techniques) to release at the front of the spine. This makes your child’s spine more flexible.
In this surgery, the doctor will:
- Use special equipment to view the procedure on a monitor
- Insert tiny tools into your child’s chest through small cuts (incisions) to correct the spinal curve
- Do spinal fusion as described above
-
Surgery for congenital kyphosis
To treat congenital kyphosis, doctors often:
- Remove the problem vertebrae. They do this to relieve pressure on the spinal cord that can cause and help correct the curve.
- Correct the problem using metal rods and screws or hooks, as described above.
