Sever?s disease is repetitive micro trauma or overuse of the heel in young athletes. Sever?s is caused by overloading the insertion of the Achilles tendon onto the calcaneus and the apophyseal growth plate. Active Children (7 to 15 years), particularly during the pubertal growth spurt or at the beginning of a sport season (e.g. gymnasts, basketball and football players), often suffer from this condition.
There is no specific known cause of Sever?s disease. However, there are several common factors associated with the condition including. Tight calf muscles. Pronated foot type (rolled in towards the ankle). Children who are heavier. Puberty/growth spurts. External factors, e.g. hard surfaces or poor footwear. Increase in physical activity levels.
In Sever?s disease, heel pain can be in one or both heels. It usually starts after a child begins a new sports season or a new sport. Your child may walk with a limp. The pain may increase when he or she stands on tiptoe. Your child?s heel may hurt if you squeeze both sides toward the very back. This is called the squeeze test. Your provider may also find that your child?s heel tendons have become tight.
To diagnose the cause of the child?s heel pain and rule out other more serious conditions, the foot and ankle surgeon obtains a thorough medical history and asks questions about recent activities. The surgeon will also examine the child?s foot and leg. X-rays are often used to evaluate the condition. Other advanced imaging studies and laboratory tests may also be ordered.
Non Surgical Treatment
First, your child should cut down or stop any activity that causes heel pain. Apply ice to the injured heel for 20 minutes 3 times a day. If your child has a high arch, flat feet or bowed legs, your doctor may recommend orthotics, arch supports or heel cups. Your child should never go barefoot. If your child has severe heel pain, medicines such as acetaminophen (one brand name: Tylenol) or ibuprofen (some brand names: Advil, Motrin, Nuprin) may help.
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.
