Sever?s disease (also known as calcaneal apophysitis) is a type of bone injury in which the growth plate in the lower back of the heel, where the Achilles tendon (the heel cord that attaches to the growth plate) attaches, becomes inflamed and causes pain. Sever?s disease is the most common cause of heel pain in children, especially those who exercise or play sports on a regular basis.
The condition generally occurs in active children at early adolescence during rapid growth periods as the heel bone can grow faster than the leg muscles causing them to become tight and overstretched. Sever?s disease most often caused by inadequate footwear, playing sport on hard surfaces, calf tightness and biomechanical problems.
Adolescents suffering from Sever?s disease usually complain of pain at the back of their heel which is often worse after exercising. It is most common between the ages of 10-12 in boys and 8-10 in girls due to the rapid growth spurts that occur during this time. It can however happen anytime up until the age of 15. Whilst most people present with pain worse in one foot, it is very common to have symptoms in both feet.
Your podiatrist will take a comprehensive medical history and perform a physical examination including a gait analysis. The assessment will include foot posture assessment, joint flexibility (or range of motion), biomechanical assessment of the foot, ankle and leg, foot and leg muscle strength testing, footwear assessment, school shoes and athletic footwear, gait analysis, to look for abnormalities in the way the feet move during gait, Pain provocation tests eg calcaneal squeeze test. X-rays are not usually required to diagnose Sever?s disease.
Non Surgical Treatment
There is nothing you can do to stop severs disease. It will stop when you finish growing. However the following will help to relieve the symptoms. Rest. Cut down on the time you spend playing sport until the pain has gone. Avoid sports that involve a lot of running or jumping. Swimming can be a useful alternative. Ice the affected area for ten to 15 minutes, especially after activity. Make sure you protect the skin by wrapping the ice in a towel. Elevate (raise) the leg when painful and swollen especially after sports. Pain relieving medication may reduce pain and swelling, but you need to discuss options with a pharmacist or GP. Always wear shoes. Avoid activities in bare feet. Choose a supportive shoe with the laces done up.
To reduce the risk of heel pain or sore heels from Sever?s Disease. Only wear properly fitting shoes. A lace up shoe with a firm heel counter. Stretch calf and foot before exercising or playing sports. Properly taping the foot provides excellent protection and immediate pain relief. Wear shoe inserts or an over-the-counter orthotic. If the problem persists, consult your foot doctor.
