The true name of this complaint is calcaneal apophysitis which just means an inflamation of the growth centre of the bone in your heel as a result of pulling by the Achilles tendon - it is important
to realise that it is not a disease but rather a condition that develops in the growing skeleton with activity. It is the most common cause of heel pain in young athletes, and is the second most
common condition of its kind in the younger athelete after Osgood-Schlatter's disease. It is often seen at a time of rapid growth during which the muscles and soft tissues become tighter as the bones
get longer. It occurs more in boys than girls and is seen most commonly between the ages of 8 and 14 years though it tends to be more prevalent in the younger of this group.
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 a lot of heel movement. It can be associated with
starting a new sport, or the start of a new season. Children who are going through adolescence are also at risk of getting it because the heel bone grows quicker than the leg. Too much weight bearing
on the heel can also cause it, as can excessive traction since the bones and tendons are still developing. It occurs more commonly in children who over-pronate, and involves both heels in more than
half of patients.
Athletes with Sever?s disease are typically aged 9 to 13 years and participate in running or jumping sports such as soccer, football, basketball, baseball, and gymnastics. The typical complaint is
heel pain that develops slowly and occurs with activity. The pain is usually described like a bruise. There is rarely swelling or visible bruising. The pain is usually worse with running in cleats or
shoes that have limited heel lift, cushion, and arch support. The pain usually goes away with rest and rarely occurs with low-impact sports such as bicycling, skating, or swimming.
Physical examination varies depending on the severity and length of involvement. Bilateral involvement is present in approximately 60% of cases. Most patients experience pain with deep palpation at
the Achilles insertion and pain when performing active toe raises. Forced dorsiflexion of the ankle also proves uncomfortable and is relieved with passive equinus positioning. Swelling may be present
but usually is mild. In long-standing cases, the child may have calcaneal enlargement.
Non Surgical Treatment
The immediate goal of treatment is pain relief. Because symptoms generally worsen with activity, the main treatment for Sever's disease is rest, which helps to relieve pressure on the heel bone,
decreasing swelling and reducing pain. As directed by the doctor, a child should cut down on or avoid all activities that cause pain until all symptoms are gone, especially running barefoot or on
hard surfaces because hard impact on the feet can worsen pain and inflammation. The child might be able to do things that do not put pressure on the heel, such as swimming and biking, but check with
a doctor first.
Exercises that help to stretch the calf muscles and hamstrings are effective at treating Sever's disease. An exercise known as foot curling, in which the foot is pointed away from the body, then
curled toward the body in order to help stretch the muscles, has also proven to be very effective at treating Sever's disease. The curling exercise should be done in sets of 10 or 20 repetitions, and
repeated several times throughout the day.
