Sever?s disease is a heel problem that is the most common cause of heel pain that commonly occurs in children. It is caused by repetitive use and overuse of the heel while it is still growing, therefore is more common in active children and teenagers. Despite the name, Sever?s Disease like Osgood- Schlatter disease is caused by overuse and is not a disease.
The most common of the Sever?s disease causes is when the heel bone grows more rapidly than the muscles and tendons in the leg. The muscles and tendons become tight and put additional stress on the growth plate in the heel. When this happens, the growth plate begins to swell, becomes tender, and the child will essentially begin to feel one or more Sever?s disease symptoms. It can occur in any child as they grow, but there are some common Sever?s disease causes and risk factors that make a child more prone to the condition. They include participation in sports and other activities that put pressure on the heel, such as basketball, track, and gymnastics. A pronated foot, which makes the Achilles tendon tight, increasing the strain on the growth plate of the heel. An arch that is flat or high, affecting the angle of the heel. Short leg syndrome, when one leg is shorter than the other, causing the shorter leg to pull more on the Achilles tendon in order to reach the ground. Obesity puts extra weight on the growth plate, which can cause it to swell.
Often the condition is self limiting; meaning as the growth plate fuses to the rest of the heel bone, the pain will subside. However in some cases the child will have so much discomfort that they will be unable to walk comfortably if left untreated. Therefore, heel pain in children should always by evaluated by a physician.
Most often, a healthcare professional can diagnose Sever?s disease by taking a careful history and administering a few simple tests during the physical exam. A practitioner may squeeze the heel on either side; when this move produces pain, it may be a sign of Sever?s disease. The practitioner may also ask the child to stand on their tiptoes, because pain that occurs when standing in this position can also be an indication of Sever?s disease.
Non Surgical Treatment
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.
Sever?s disease is self-recovering, meaning that it will go away on its own when the foot is used less or when the bone is through growing. The condition is not expected to create any long-term disability, and expected to subside in 2-8 weeks. The disease may also take several years to stop, because it is often triggered by growing too fast. It is more common in boys, although occurs in girls as well. The average age of symptom onset is 9-11.
