Sever's disease (calcaneal apophysitis) is a common cause of heel pain, particularly in physically active young people who are about to begin puberty. The cause is uncertain, but it is thought that
the long calf bones of the leg grow faster than the surrounding muscle and soft tissue, causing the Achilles tendon to pull uncomfortably tight.
Sever's disease can result from standing too long, which puts constant pressure on the heel. Poor-fitting shoes can contribute to the condition by not providing enough support or padding for the feet
or by rubbing against the back of the heel. Although Sever's disease can occur in any child, these conditions increase the chances of it happening. Pronated foot (a foot that rolls in at the ankle
when walking), which causes tightness and twisting of the Achilles tendon, thus increasing its pull on the heel's growth plate. Flat or high arch, which affects the angle of the heel within the foot,
causing tightness and shortening of the Achilles tendon. Short leg syndrome (one leg is shorter than the other), which causes the foot on the short leg to bend downward to reach the ground, pulling
on the Achilles tendon. Overweight or obesity, which puts weight-related pressure on the growth plate.
The main symptom of sever's disease is pain and tenderness at the back of the heel which is made worse with physical activity. Tenderness will be felt especially if you press in or give the back of
the heel a squeeze from the sides. There may be a lump over the painful area. Another sign is tight calf muscles resulting with reduced range of motion at the ankle. Pain may go away after a period
of rest from sporting activities only to return when the young person goes back to training.
To diagnose the cause of the child?s heel pain and rule out other more serious conditions, the foot and ankle surgeon obtains a thorough medical history and asks questions about recent activities.
The surgeon will also examine the child?s foot and leg. X-rays are often used to evaluate the condition. Other advanced imaging studies and laboratory tests may also be ordered.
Non Surgical Treatment
Sever?s disease treatment should be based on eliminating pain and restoring normal foot and leg biomechanics. As with most soft tissue injuries the initial treatment is Rest, Ice, and Protect. In the
early phase you?ll most likely be unable to walk pain-free. Our first aim is to provide you with some active rest from pain-provoking activities. "No Pain. No Gain." does not apply in Sever's
disease. If it hurts your child is doing too much exercise. Your child should reduce or cease any activity that causes heel pain. Ice is a simple and effective modality to reduce your pain and
swelling. Please apply for 20-30 minutes each 2 to 4 hours during the initial phase or when you notice that your injury is warm or hot. Most children can tolerate paracetamol as a pain reducing
medication. Check with your doctor. To support and protect your heels, you may need to be wear shock absorbing heel cups or a soft orthotic. Kinesio foot taping may help to provide pain relief.
Perform a well rounded dynamic warm up before activity. Perform a good static stretching routine after activity. Increase core strength. Perform exercises that emphasize active lengthening of the
calf muscles. Use proper footwear. Avoid excessive running or jumping on hard surfaces like concrete by using better surfaces such as asphalt, gymnasium floors or grass.
