Sever's disease (calcaneal apophysitis) is a common cause of heel pain, particularly in physically active young people who are about to begin puberty. The cause is uncertain, but it is thought that the long calf bones of the leg grow faster than the surrounding muscle and soft tissue, causing the Achilles tendon to pull uncomfortably tight.
Contraction of the calf muscles along with the rapid growth of the leg bone (tibia), decreases ankle motion and increases strain on the heel area. This puts strain on the Achilles tendon. Injury results from repetitive pulling through the heel bone by the Achilles and the traction forces from the plantar fascia.
Symptoms include heel pain related to sports activities and worsen after those sport and exercise activities. However, some children who are not in a sport may also get this if they are physically active. If you notice that your child is ?walking on their toes? this is a sign of possible heel pain. The pain is usually on the back of the heel, the sides of the heel, the bottom of the heel, or a combination of all of these. We typically don't see swelling with this, however if pressure is applied to the sides of the heel pain may be reported. Sometimes the pain is so bad the child will have to limp, or take a break from sports activity either for a few days or few months.
Sever's disease is based on the symptoms reported. To confirm the diagnosis, the clinician will examine the heels and ask about the child's activity level and participation in sports. They may also squeeze the back part of the heel from both sides at the same time to see if doing so causes pain and also ask the child to stand on tiptoes to see if that position causes pain. There may be tightness in the calf muscle, which contributes to tension on the heel. Symptoms are usually worse during or after activity and get better with rest. X-rays generally are not that helpful in diagnosing Sever's disease, but they may be ordered to rule out other problems, such as fractures. Sever's disease cannot be seen on an X-ray.
Non Surgical Treatment
The doctor will talk with you about the best treatment plan for your child. As instructed, your child will Ice the heel 3-4 times a day for 15-20 minutes at a time. Use an ice pack or bag of frozen peas, or something similar. Never put ice directly on your child's skin. A thin cloth or towel should be between your child?s skin and the ice pack. Take anti-inflammatory medication, such as ibuprofen, as directed. Decrease the amount of running and jumping he or she does. Stretch the heels and calves, as instructed by the doctor. Regular stretching can help prevent Sever?s from coming back. Use a ?heel cup? or a cushioned shoe insert that takes pressure off the heel. In some cases, a cast is placed on the foot and worn for several weeks.
To reduce the risk of heel pain or sore heels from Sever?s Disease. Only wear properly fitting shoes. A lace up shoe with a firm heel counter. Stretch calf and foot before exercising or playing sports. Properly taping the foot provides excellent protection and immediate pain relief. Wear shoe inserts or an over-the-counter orthotic. If the problem persists, consult your foot doctor.
