Overview
Sever?s disease is a painful condition of the heel affecting children, usually at the beginning of the growth spurt in early puberty. It is caused by inflammation at the growth plate at the back of the heel, adjacent to the Achilles tendon attachment. This is one of the most common causes of heel pain in school-aged children. Physically active children aged between eight and fourteen years old are most at risk of developing pain from Sever?s disease. It is common among children involved in soccer, little athletics, gymnastics, basketball and netball but can affect children involved in any running or jumping activity. Boys seem to be more commonly affected than girls.
Causes
Heel pain is very common in children due to the fact they are cnstantly growing. In most children, the heel bone (the calcaneus) is not fully developed until the age of 14 or older. Until then, new bone is forming at the growth plate of the foot (the apophysis, located at the back of the heel), an area which is softer than others due to its role in accommodating the growth. Repetitive stress on the growth plate due to walking, running and sports causes inflammation in the heel area. Because the heel's growth plate is sensitive, repeated running and pounding on hard surfaces can result in pediatric heel pain. Children and adolescents who take part in a lot of sport are especially vulnerable. Over-pronation (fallen arches and rolling inwards of the feet) will increase the impact on the growth plate and is therefore a significant cause and a major contributing factor to heel pain in children.
Symptoms
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.
Diagnosis
Sever's disease is based on the symptoms reported. To confirm the diagnosis, the clinician will examine the heels and ask about the child's activity level and participation in sports. They may also squeeze the back part of the heel from both sides at the same time to see if doing so causes pain and also ask the child to stand on tiptoes to see if that position causes pain. There may be tightness in the calf muscle, which contributes to tension on the heel. Symptoms are usually worse during or after activity and get better with rest. X-rays generally are not that helpful in diagnosing Sever's disease, but they may be ordered to rule out other problems, such as fractures. Sever's disease cannot be seen on an X-ray.
Non Surgical Treatment
If the child has a pronated foot, a flat or high arch, or another condition that increases the risk of Sever's disease, the doctor might recommend special shoe inserts, called orthotic devices, such as heel pads that cushion the heel as it strikes the ground, heel lifts that reduce strain on the Achilles tendon by raising the heel, arch supports that hold the heel in an ideal position. If a child is overweight or obese, the doctor will probably also recommend weight loss to decrease pressure on the heel. The risk of recurrence goes away on its own when foot growth is complete and the growth plate has fused to the rest of the heel bone, usually around age 15.
Exercise
Stretching exercises can help. It is important that your child performs exercises to stretch the hamstring and calf muscles, and the tendons on the back of the leg. The child should do these stretches 2 or 3 times a day. Each stretch should be held for about 20 seconds. Both legs should be stretched, even if the pain is only in 1 heel. Your child also needs to do exercises to strengthen the muscles on the front of the shin. To do this, your child should sit on the floor, keeping his or her hurt leg straight. One end of a bungee cord or piece of rubber tubing is hooked around a table leg. The other end is hitched around the child's toes. The child then scoots back just far enough to stretch the cord. Next, the child slowly bends the foot toward his or her body. When the child cannot bend the foot any closer, he or she slowly points the foot in the opposite direction (toward the table). This exercise (15 repetitions of "foot curling") should be done about 3 times. The child should do this exercise routine a few times daily.
