Another name for Sever?s Disease is calcaneal apophysitis. The heel bone is called the calcaneus. Sever?s Disease is heel pain thought to be caused by inflammation around the growth plate in the calcaneus (apophysis). It is most likely due to repetitive overuse during sports and exercise, which causes increased strain on the heel growth plate. Sever?s Disease won?t cause long-term damage or arthritis. Sever?s Disease is often associated with tight heel tendons. It most commonly affects physically active children who are between the ages of 8, 14 years old, such as soccer players and gymnasts.
Sever's disease is caused by repetitive tension and/or pressure on the growth center of the heel. Running and jumping place a large amount of pressure on the heels and can cause pain. Children with Sever's may limp or have an altered gait due to the pain. Risk factors for Sever's include tight calf muscles, weak ankle muscles, and alignment abnormalities at the foot and ankle. Sever's can also result from wearing shoes without sufficient heel padding or arch support.
Sever's Disease is most commonly seen in physically active girls and boys from ages 10 to 15 years old. These are the years when the growth plate is still ""open,"" and has not fused into mature bone. Also, these are the years when the growth plate is most vulnerable to overuse injuries, which are usually caused by sports activities. The most common symptoms of this disease include. Heel pain in one or both heels. Usually seen in physically active children, especially at the beginning of a new sports season. The pain is usually experienced at the back of the heel, and includes the following areas. The back of the heel (that area which rubs against the back of the shoe). The sides of the heel. Actually, this is one of the diagnostic tests for Sever's Disease, squeezing the rear portion of the heel from both sides at the same time will produce pain. It is known as the Squeeze Test.
A physical exam of the heel will show tenderness over the back of the heel but not in the Achilles tendon or plantar fascia. There may be tightness in the calf muscle, which contributes to tension on the heel. The tendons in the heel get stretched more in patients with flat feet. There is greater impact force on the heels of athletes with a high-arched, rigid foot.
Non Surgical Treatment
The doctor might recommend that a child with Sever's disease perform foot and leg exercises to stretch and strengthen the leg muscles and tendons, elevate and apply ice (wrapped in a towel, not applied directly to the skin) to the injured heel for 20 minutes two or three times per day, even on days when the pain is not that bad, to help reduce swelling, use an elastic wrap or compression stocking that is designed to help decrease pain and swelling, take an over-the-counter medicine to reduce pain and swelling, such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin). Children should not be given aspirin for pain due to the risk of a very serious illness called Reye syndrome. In very severe cases, the doctor might recommend that the child wear a cast for anywhere from 2 to 12 weeks to immobilize the foot so that it can heal.
It is important to undertake correct warm ups and warm downs before and after exercise. This should include a stretching routine. It may be necessary to undertake additional stretching outside of sport, especially during stages of growth. Only playing one sport should be avoided. You should not allow your child to play through pain.
