Overview
Sever’s disease is a pain that occurs in the back of the heel of physically active children at around the time of puberty. Sever’s disease occurs due to an inflammation of the growth plate due to excessive pull of the achilles tendon on this growth plate. During puberty the bones quite often grow faster than the muscles and tendons causing the tendons to become tight, this tightness then results in excessive pull on the back of the heel resulting in this painful condition.
Causes
The condition generally occurs in active children at early adolescence during rapid growth periods as the heel bone can grow faster than the leg muscles causing them to become tight and overstretched. Sever?s disease most often caused by inadequate footwear, playing sport on hard surfaces, calf tightness and biomechanical problems.
Symptoms
Pain is usually felt at the back of the heel and around the sides of the heel. If you squeeze the back of the heel from both sides simultaneously and pain is experienced Sever?s disease is more than likely present.
Diagnosis
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
Primary treatment involves the use of heel cups or orthotics with a sturdy, supportive plastic shell. Treatment may also include cutting back on sports activities if pain interferes with performance, calf muscle stretching exercises, icing, and occasionally anti-inflammatory medications. Severe cases may require the short term use of a walking boot or cast.
Prevention
Properly stretching to maintain flexibility is effective for preventing Sever’s disease. Stretches should target the calves, heel cords, and hamstrings. Your child should do the appropriate stretches two or three times a day, holding the stretch for about 20 seconds each time. Ask your child’s doctor for specific exercise instructions. Generally, doctors advise stretching both legs, even if the pain is confined to one heel. It’s also helpful to strengthen the shin muscles by having your youngster pull his toes in with a rubber exercise band or a piece of tubing and then stretch them forward. Assist your child in doing 15 repetitions of this exercise, three times a day. Having your child wear shoes with good shock absorbers and avoid running on hard surfaces as much as possible should also help prevent the condition.
