Back pain isn’t an adults-only problem. It also affects children, and spondylolysis — a break in a vertebra — is a common cause.
If your child tells you their low back hurts, especially during physical activity, have a medical provider check it out as quickly as possible. If spondylolysis is present, early diagnosis and treatment can prevent a more serious injury to the vertebra called spondylolisthesis. The sooner your child starts treatment, the sooner they can get back to enjoying an active childhood.
Spondylolysis vs. Spondylolisthesis: What’s the Difference?
Spondylolysis is a stress fracture that develops in a vertebra, one of a column of bones that protects the spinal cord. Along the spine, pairs of facet joints help stabilize the vertebrae. A thin piece of vertebra called the pars interarticularis links these joints. Spondylolysis affects this bony connector, most commonly in the vertebrae of the lumbar spine (lower spine).
Without treatment, spondylolysis can lead to spondylolisthesis, which is when the pars interarticularis splits. As a result, the vertebra slips out of position, potentially causing pain and nerve damage.
Who’s at Risk for Stress Fractures of the Spine
Repeatedly overstretching the spine stresses the vertebrae, which are especially vulnerable to stress fractures during childhood because they’re still growing. Your child may have a higher risk of spondylolysis and spondylolisthesis if they participate in sports or activities that involve frequently leaning back and moving the lumbar spine, including:
- Ballet
- Football
- Golf
- Gymnastics
- Soccer
- Volleyball
- Cheerleading
- Weightlifting
- Wrestling
When Back Pain Is a Red Flag
Sometimes, stress fractures of the vertebrae develop silently, without causing symptoms. In other cases, however, these bone breaks provide clues to their presence. Back pain is the main one.
Spondylolysis in a lumbar vertebra can cause low back pain that feels like a muscle strain. Your child’s discomfort may get worse with activity and improve with rest. Other symptoms of spondylolysis include pain in the legs and buttocks, which may be a sign the pain has spread from the back. Spasms from the stress fracture can cause your child’s hamstrings to tighten.
Diagnosing and Treating Spondylolysis
If you notice symptoms of spondylolysis, take your child to their primary care provider, who will ask about medical history and sports participation. The medical provider will also perform a physical exam to look for signs of a stress fracture in the low back and legs. He or she may press on your child’s back to identify tender areas or ask your child to bend backward to see if the movement causes discomfort.
Imaging tests, such as X-rays and CT scans, can show stress fractures in the vertebrae and help your child’s medical provider confirm a spondylolysis diagnosis. MRI scans can show whether a stress fracture has led to tissue damage.
Your child’s primary care provider may refer you to a pediatric orthopedic specialist for further evaluation and treatment. If found early, spondylolysis usually heals with nonsurgical treatment.
Your child may need to take a temporary break from sports that put repetitive stress on the low back to give the fracture time to heal. To help the process, they may need to wear a back brace to limit the spine’s movement.
While the injury heals, your child may take over-the-counter pain-relieving medications to stay comfortable. Working with a physical therapist can also help reduce pain and improve strength and flexibility in the lumbar spine.
Surgery isn’t usually necessary. However, if spondylolysis leads to severe spondylolisthesis, spinal fusion may be the most appropriate treatment. During this operation, a surgeon connects two damaged vertebrae using a bone graft so the vertebrae heal into a single, stable bone.
How to Reduce Your Child’s Risk of Spondylolysis
You can help protect your child’s spine and keep him or her on the field or court by encouraging simple steps to reduce the risk of spondylolysis, including:
- Build strength in the middle. Encourage your child to strengthen his or her core to help support the lower back.
- Focus on one sport at a time to prevent overuse injuries. Don’t let your child play more than one sport that increases the risk of a spinal stress fracture per season.
- Play it smart. Ensure your child uses the proper equipment and technique for his or her sport.
- Rest up. Your child should take at least one day off from practice or training each week.
- Eat a balanced diet. Maintain a healthy diet with adequate calcium and protein intake. Vitamin D supplementation is especially necessary for those missing key nutrients in their diet.
