The condition is more common in young people active in sport, and boys are more frequently affected than girls. One study found the average age of presentation was around 12 years for boys and 9 years for girls. In one prospective study of injuries among players aged 9-19 years in football academies, 2% of overall football injuries were due to Sever's disease; the peak for incidence was in the under-11 age group. In a study of 85 children, the condition was bilateral in 61%.
Sever?s Disease is thought to be caused by several reasons. Growth spurts. The muscles and tendons become tight due to rapid bone growth. Overuse. Sever?s Disease can also occur in children who are athletically active and overwork his or her muscles. Some physicians are beginning to caution parents about checking their children?s shoes to make sure they fit well and do not pinch or put undue pressure on the child?s feet. Pronation can also bring on Sever?s Disease.
The pain is at the heel or around the Achilles tendon. This is felt commonly during exercise, particularly activities involving running or jumping. The back of the heel may also be tender to touch and there may be localised swelling. There may be stiffness in the calf muscles first thing in the morning and you may notice limping or a tendency to tiptoe.
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
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.
This condition is self limiting, it will go away when the two parts of bony growth join together, this is natural. Unfortunately, Sever's disease can be very painful and limit sport activity of the child while waiting for it to go away, so treatment is often advised to help relieve it. In a few cases of Sever's disease, the treatment is not successful and these children will be restricted in their activity levels until the two growth areas join, usually around the age of 16 years. There are no known long term complications associated with Sever's disease.
