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%.
The heel bone grows faster than the ligaments in the leg. As a result, muscles and tendons can become very tight and overstretched in children who are going through growth spurts. The heel is
especially susceptible to injury since the foot is one of the first parts of the body to grow to full size and the heel area is not very flexible. Sever?s disease occurs as a result of repetitive
stress on the Achilles tendon. Over time, this constant pressure on the already tight heel cord can damage the growth plate, causing pain and inflammation. Such stress and pressure can result from,
Sports that involve running and jumping on hard surfaces (track, basketball and gymnastics). Standing too long, which puts constant pressure on the heel. Poor-fitting shoes that don?t provide enough
support or padding for the feet. Overuse or exercising too much can also cause Sever?s disease.
Symptoms include complaints of pain or tenderness in the heel (or heels), discomfort when heel is squeezed, limping, and more severe pain after walking, running or playing sports. Sever?s disease is
directly related to overuse of the bone and tendons in the heel. This can come from playing sports or anything that involves lots of heel movements and hard shoes such as cleats. It can be associated
with starting a new sport, or the start of a new season. It occurs more commonly in children who pronate (feet roll inward), and involves both heels in more than half of patients.
You may have pain when your doctor squeezes your heel bone. You may have pain when asked to stand or walk on your toes or on your heels. You may have pain in your heel when your doctor stretches your
calf muscles. Your doctor may order x-rays of the injured foot to show an active growth plate.
Non Surgical Treatment
Once diagnosed, there is a list of treatment options available to begin the recovery process. Unfortunately due to the nature of the condition it will often be a reoccurring condition until closure
of the growth plates of the heel and elongation of the soft tissue structures. However with appropriate education, correct management of symptoms and prevention strategies, Severs disease can be well
managed by the individual and their parents.
