Severs disease or calcaneal apophysitis causes heel pain usually in growing children between age nine and fourteen. It occurs as a result of disturbance during the final development of the heel growth plate. During this time the achilles tendon is pulling strongly on the heel bone and this excessive force can cause inflammation and pain.
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
A few signs and symptoms point to Sever?s disease, which may affect one or both heels. These include pain at the heel or around the Achilles tendon, Heel pain during physical exercise, especially activities that require running or jumping, worsening of pain after exercise, a tender swelling or bulge on the heel that is sore to touch, calf muscle stiffness first thing in the morning, limping, a tendency to tiptoe.
Your Podiatrist or Physiotherapist will assist in diagnosing the injury and the extent of the damage. From this, they will develop a management plan which may include rest or activity modification, soft tissue treatment such as massage and stretching, correction of biomechanics through heel raises or orthoses and the progression through a series of specific strengthening exercises.
Non Surgical Treatment
Treatment of Severs disease usually involves a combination of an accurate analysis of your child?s gait, muscles, tendons, ligaments and joints is a crucial first step. Specific stretching and strengthening exercises often make up part of the treatment. Anti-inflammatory measures such as ice baths after exercise can be helpful in the short term. Footwear review, assessment and advice is important. Orthotic devices are often needed to firstly control any abnormal traction or tension on the heel growth plate and, secondly, too unload the ground reaction forces on the heel bone. Podiatry Care has podiatrists with specific paediatric training enabling them to utilise treatment options to relieve heel pain in children very quickly. If your child is struggling to play sport, see a Podiatry Care podiatrist near you. In severe cases modification to activity levels may be required. Treatment of Severs disease does NOT require surgery. This foot condition responds very well to conservative treatment.
