Sever's disease is an overuse syndrome involving an immature part of the skeleton. Pain goes away when the overuse is over, or when the growing is done. Hence, the disease is self-limited, in that the pain goes away eventually when growth in the heel bone is complete at about age 13. Even if the child is hurting, as long as he can tolerate it, he may continue to take part in sports. No long term disability is expected from this problem.
During the growth spurt of early puberty, the heel bone (also called the calcaneus) sometimes grows faster than the leg muscles and tendons. This can cause the muscles and tendons to become very tight and overstretched, making the heel less flexible and putting pressure on the growth plate. The Achilles tendon (also called the heel cord) is the strongest tendon that attaches to the growth plate in the heel. Over time, repeated stress (force or pressure) on the already tight Achilles tendon damages the growth plate, causing the swelling, tenderness, and pain of Sever's disease. Such stress commonly results from physical activities and sports that involve running and jumping, especially those that take place on hard surfaces, such as track, basketball, soccer, and gymnastics.
The typical clinical presentation is an active child (aged 9-10 years) who complains of pain at the posterior heel that is made worse by sports, especially those involving running or jumping. The onset is usually gradual. Often, the pain has been relieved somewhat with rest and consequently has been patiently monitored by the patient, parents, coaches, trainers, and family physicians, in the expectation that it will resolve. When the pain continues to interfere with sports performance and then with daily activities, further consultation is sought. It should be kept in mind that failure to instruct patients and parents that continual pain, significant swelling or redness, and fever are not signs of Sever disease and therefore require further evaluation could result in failure to diagnose a condition with much more serious long-term consequences.
A doctor can usually tell that a child has Sever's disease based on the symptoms reported. To confirm the diagnosis, the doctor will probably examine the heels and ask about the child's activity level and participation in sports. The doctor might also use the squeeze test, squeezing the back part of the heel from both sides at the same time to see if doing so causes pain. The doctor might also ask the child to stand on tiptoes to see if that position causes pain. Although imaging tests such as X-rays generally are not that helpful in diagnosing Sever's disease, some doctors order them to rule out other problems, such as fractures. Sever's disease cannot be seen on an X-ray.
Non Surgical Treatment
Rest is best to allow healing .Only do as much exercise as able without causing pain. Many children can continue to play sports but if pain is severe then stopping the activity may be the only way to allow the pain to settle. The child might be able to do things that do not put pressure on the heel, such as swimming and cycling. Ice and cold therapy may be useful to reduce pain and swelling, particularly following activity or sport. The area should be iced until it feels cold not ?frozen?. Never apply ice directly onto the skin, as this may cause tissue damage. Medication. The following will help treat your child?s pain. Paracetamol (see bottle for instructions) Ibuprofen (see bottle for instructions). Exercises, perform foot and leg exercises to stretch and strengthen the leg muscles & tendons. Increase calf flexibility by doing calf stretches several times per day. Protect the heel, your shoes might need a heel lift or arch support. Select a shoe with good arch support and heel lift if possible. Take it one step at a time: gradually resume running and impact activities as symptoms allow.
Sever's Disease may be prevented by maintaining good flexibility while the child is growing. The stretching exercises can help lower the risk for injuries during a growth spurt. Having good quality shoes with firm support and a shock-absorbent sole will also help. Child should also avoid excessive running on hard surfaces.
