Sever?s disease, also known as calcaneal apophysitis, is a common heel problem affecting children. This heel bone disorder is often painful, though it?s usually temporary and causes no long-term health effects. With Sever?s disease, the Achilles tendon repeatedly pulls on the heel?s growth plate, causing microtrauma (i.e. microfractures), inflammation, and swelling in the affected area. Sever?s disease is similar to Osgood-Schlatter disease, which affects the knee. Inappropriate footwear may be a contributing factor in the onset of this condition.
The more active a child is then the greater the chance of suffering from Sever?s disease. Poor foot function such as flat feet causes the calf and Achilles to work harder and pull on the growth plate leading to Sever?s disease. Tight calves or Achilles is common in growing children and can increase tension on the growth plate.
Sever’s disease usually develops gradually. The pain from Sever’s disease is often intermittent and localized to the area where the Achilles tendon attaches to the calcaneus. Swelling may be noted in this area. There can be tenderness on squeezing the calcaneus or pain when trying to stretch the calf muscles. Occasionally there is night pain. As Sever’s disease progresses there can be continuous pain.
Sever’s disease is diagnosed based on a doctor?s physical examination of the lower leg, ankle, and foot. If the diagnosis is in question, the doctor may order X-rays or an MRI to determine if there are other injuries that may be causing the heel pain.
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.
It is important to undertake correct warm ups and warm downs before and after exercise. This should include a stretching routine. It may be necessary to undertake additional stretching outside of sport, especially during stages of growth. Only playing one sport should be avoided. You should not allow your child to play through pain.
