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.
The symptoms of Sever?s disease occur in the heel and the foot, and may worsen with activity. Pain and stiffness can occur in one or both heels. Symptoms can include. Swelling in the heel. Redness in
the heel. Antalgic gait (such as limping). Foot pain or stiffness first thing in the morning or while walking. Pain that is worsened by squeezing the heel.
Sever?s disease can be diagnosed based on your history and symptoms. Clinically, your physiotherapist will perform a "squeeze test" and some other tests to confirm the diagnosis. Some children suffer
Sever?s disease even though they do less exercise than other. This indicates that it is not just training volume that is at play. Foot and leg biomechanics are a predisposing factor. The main factors
thought to predispose a child to Sever?s disease include a decrease in ankle dorsiflexion, abnormal hind foot motion eg overpronation or supination, tight calf muscles, excessive weight-bearing
activities eg running.
Non Surgical Treatment
Occasionally, an orthotic may need to be prescribed for temporary or long-term correction of their foot biomechanics (eg flat feet or high arches). During the acute phase of Sever's disease a small
heel rise or shock-absorbing heel cup placed under the heel pad of your child's foot may help to ease the symptoms. Your podiatrist or physiotherapist can assess your child's arch and guide you in
the best management of your child's condition. We recommend that your child should never go barefooted during the painful stages of Sever's disease.
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.
