Overview
Sever's disease or Calcaneal apophysitis is a condition that affects children between the ages of 10 and 13 years. It is characterized by pain in one or both heels with walking. During this phase of life, growth of the bone is taking place at a faster rate than the tendons. Hence there is a relative shortening of the heel-cord compared to the leg bones. As a result, the tension the heel-cord applies to the heel bone at its insertion is very great. Moreover, the heel cord is attached to a portion of the calcaneus (heel bone) that is still immature, consisting of a mixture of bone and growing cartilage, called the calcaneal apophysis, which is prone to injury. Compounding to this is the fact that all these changes are happening in a very active child, prone to overuse. The end result is therefore an overuse syndrome of injury and inflammation at the heel where the heel cord (Achilles Tendonitis) inserts into the heel bone (Calcaneal apophysitis).
Causes
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
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.
Diagnosis
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
Resting the foot and applying ice to the affected area are some of the most effective methods when it comes to treating Sever?s Disease. Make sure the ice is always wrapped in a cloth of some sort. Applying ice directly to the skin can cause frostbite. A monitored stretching program of the lower limbs (particularly of the calf muscles) as well as a small heel lift may also be suggested.
Recovery
If the child has a pronated foot, a flat or high arch, or another condition that increases the risk of Sever's disease, the doctor might recommend special shoe inserts, called orthotic devices, such as heel pads that cushion the heel as it strikes the ground, heel lifts that reduce strain on the Achilles tendon by raising the heel, arch supports that hold the heel in an ideal position. If a child is overweight or obese, the doctor will probably also recommend weight loss to decrease pressure on the heel. The risk of recurrence goes away on its own when foot growth is complete and the growth plate has fused to the rest of the heel bone, usually around age 15.
