Sever disease, first described in 1912, is a painful inflammation of the calcaneal apophysis. It is classified with the child and adolescent nonarticular osteochondroses. (The other disease in this
group is Iselin disease, which is inflammation of the base of the fifth metatarsal.) The etiology of pain in Sever disease is believed to be repetitive trauma to the weaker structure of the
apophysis, induced by the pull of the tendo calcaneus (Achilles tendon) on its insertion. This results in a clinical picture of heel pain in a growing active child, which worsens with activity. Sever
disease is a self-limited condition, accordingly, no known complication exists from failure to make the correct diagnosis.
Sever?s is often present at a time of rapid growth in adolescent athletic children. At this time the muscles and tendons become tighter as the bones become larger. Between 8 - 15 years of age is the
usual onset of this condition.
Adolescents suffering from Sever?s disease usually complain of pain at the back of their heel which is often worse after exercising. It is most common between the ages of 10-12 in boys and 8-10 in
girls due to the rapid growth spurts that occur during this time. It can however happen anytime up until the age of 15. Whilst most people present with pain worse in one foot, it is very common to
have symptoms in both feet.
A doctor can usually tell that a child has Sever's disease based on the symptoms reported. To confirm the diagnosis, the doctor will probably examine the heels and ask about the child's activity
level and participation in sports. The doctor might also use the squeeze test, squeezing the back part of the heel from both sides at the same time to see if doing so causes pain. The doctor might
also ask the child to stand on tiptoes to see if that position causes pain. Although imaging tests such as X-rays generally are not that helpful in diagnosing Sever's disease, some doctors order them
to rule out other problems, such as fractures. Sever's disease cannot be seen on an X-ray.
Non Surgical Treatment
First, your child should cut down or stop any activity that causes heel pain. Apply ice to the injured heel for 25 minutes three times a day. Your child should not go barefoot. If your child has
severe heel pain, ibuprofen (Advil) will help. It is important that your child performs exercises to stretch the hamstring and calf muscles, and the tendons on the back of the leg. The child should
do these stretches five times each, two or three times a day. Each stretch should be held for 20 seconds. Your child also needs to do exercises to strengthen the muscles on the front of the shin. To
do this, have your child stand facing a wall to stretch the calves and the heel cord. Place one foot a shoulder?s width in front of the other, both feet facing the wall. The front knee is bent and
the back knee is straight during the calf stretch. Then have your child push against the wall and feel the stretch in his or her back leg. To stretch out the heel cord, have him or her stay in the
same position and bend the back knee. Repeat three times. Practice this stretch twice daily.
The following exercises are commonly prescribed to patients with Severs disease. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally,
they should be performed 1 - 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and
eventually progress to the intermediate, advanced and other exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no
increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed
around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head as far as you can go without pain and provided you feel no more than a mild to moderate
stretch in the back of your calf, Achilles tendon or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Calf Stretch with Towel. Begin this
exercise with a resistance band around your foot and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable
without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 - 20 times provided the exercise is pain free. Once you can perform 20 repetitions consistently
without pain, the exercise can be progressed by gradually increasing the resistance of the band provided there is no increase in symptoms. Bridging. Begin this exercise lying on your back in the
position demonstrated. Slowly lift your bottom pushing through your feet, until your knees, hips and shoulders are in a straight line. Tighten your bottom muscles (gluteals) as you do this. Hold for
2 seconds then slowly lower your bottom back down. Repeat 10 times provided the exercise is pain free.
