When Your Child Has Spondylolysis or Spondylolisthesis

You have been told your child has a problem with his or her vertebrae. These are the bones that stack together to make up the spine. Spondylolysis is a defect (crack) in the back part of a vertebra. Spondylolisthesis is the slipping forward of a vertebra. Spondylolisthesis is often due to spondylolysis. But a child can have one without the other. If your child has this spine problem, he or she may see a spine specialist (doctor who treats back and spine problems).

What Are the Causes of Spondylolysis and Spondylolisthesis?

One common cause of these problems is repeated extension of the spine (bending backward). Children who do activities that require spine extension (such as gymnastics, diving, and dance) are more likely to get these problems than other children. Other activities that may increase a child’s risk include weightlifting. Some ball sports, such as football and soccer, may also make the problems more likely.

What are the Signs and Symptoms of Spondylolysis or Spondylolisthesis?

These problems almost always occur in the low back. A child can have either problem and have no symptoms. Or, he or she can have back soreness, back pain, or muscle spasms in the back. The pain can sometimes travel into the thighs and buttocks.

How are Spondylolysis and Spondylolisthesis Diagnosed?

The doctor will ask about the child’s activities and medical history. An X-ray (test that creates images of bones) is usually the only test that is needed. The problem often can be seen on an X-ray. In certain cases, other imaging tests (such as an MRI or a CT scan) may be done to get more information about your child’s spine.

How are Spondylolysis and Spondylolisthesis Treated?

These problems can’t be cured, but often stop causing problems in time. In the meantime, your child’s symptoms can be treated.

  • Medications: To help reduce back pain and swelling, medications may be prescribed. These are usually NSAIDs (nonsteroidal anti-inflammatory drugs). These medications include ibuprofen and naproxen. They may be over-the-counter or prescription. Your health care provider will tell you what types and dosage are best for your child. Give these medications to your child only as prescribed. 

  • Physical therapy: Stretching and strengthening the muscles around the spine and in the legs can help relieve symptoms due to these conditions. Your doctor may refer your child to a physical therapist (PT) for a course of physical therapy and exercises.

  • Resting the back: This means stopping any activity that stresses the back. Once your child stops having symptoms, he or she can go back to a normal activity level. If a child continues to have symptoms, a small reduction in activity may help.

  • Bracing: Your child may be fitted with a brace to wear for a few weeks to months. This brace takes stress off the spine, allowing symptoms to resolve.

  • Surgery: If spondylolisthesis is severe or can’t be treated with nonsurgical means, surgery may be done. During surgery, the slipping vertebra is fused to the vertebra below it to prevent further movement.

What are the Long-Term Concerns?

Once symptoms have been treated, spondylolysis and spondylolisthesis rarely cause further problems. But a child with these conditions should be checked regularly by the doctor as he or she grows to be sure further problems don’t develop.
