Sever’s disease is a condition characterized by pain in one or both heels with walking. The pain is caused by shortening of the heel-cord. It usually affects children between the ages of 10 and 13 years old. During this phase of life, growth of the bone is taking place at a faster rate than the tendons. Sever’s disease is also called calcaneal apophysitis.
Inflammation occurs at the insertion of the achilles tendon into the back of the heel due to a number of reasons. One or several of the following may cause the initiation of Sever?s disease. Rapid growth spurt. Tight calf muscles. Change in footwear (soccer boots / athletic shoes no heel). Excessive rolling in of feet. Poor warm up routine. Remember this condition usually settles as the growth plate fuses within 6-12 months.
Children aged between 8 to 13 years of age can experience Sever?s disease with girls being normally younger and boys slightly older. Sever?s disease normally involves the back of the heel bone becoming painful towards the end of intense or prolonged activity and can remain painful after the activity for a few hours. Severe cases can result in limping and pain that can even remain the next morning after sport.
You may have pain when your doctor squeezes your heel bone. You may have pain when asked to stand or walk on your toes or on your heels. You may have pain in your heel when your doctor stretches your calf muscles. Your doctor may order x-rays of the injured foot to show an active growth plate.
Non Surgical Treatment
The immediate goal of treatment is pain relief. Because symptoms generally worsen with activity, the main treatment for Sever’s disease is rest, which helps to relieve pressure on the heel bone, decreasing swelling and reducing pain. As directed by the doctor, a child should cut down on or avoid all activities that cause pain until all symptoms are gone, especially running barefoot or on hard surfaces because hard impact on the feet can worsen pain and inflammation. The child might be able to do things that do not put pressure on the heel, such as swimming and biking, but check with a doctor first.
Exercises that help to stretch the calf muscles and hamstrings are effective at treating Sever’s disease. An exercise known as foot curling, in which the foot is pointed away from the body, then curled toward the body in order to help stretch the muscles, has also proven to be very effective at treating Sever’s disease. The curling exercise should be done in sets of 10 or 20 repetitions, and repeated several times throughout the day.
