Sever disease, first described in 1912, is a painful inflammation of the calcaneal apophysis. It is classified with the child and adolescent nonarticular osteochondroses. (The other disease in this
group is Iselin disease, which is inflammation of the base of the fifth metatarsal.) The etiology of pain in Sever disease is believed to be repetitive trauma to the weaker structure of the
apophysis, induced by the pull of the tendo calcaneus (Achilles tendon) on its insertion. This results in a clinical picture of heel pain in a growing active child, which worsens with activity. Sever
disease is a self-limited condition; accordingly, no known complication exists from failure to make the correct diagnosis.
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.
Chief complaint is heel pain which increases pain during running and jumping activities. Pain is localized to the very posterior aspect of the heel. Pain is elicited only with weightbearing. Mild
involvement is present if pain is brought on only with running during sports. The symptoms can be severe, with pain (and possibly limp) with activities of daily living (ie walking).
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
Management by a health professional of Sever's disease is often wise. There are a few very rare problems that may be causing the pain, so a correct diagnosis is extremely important. Advice should be
given on all of what is mentioned above, appropriate activity levels, the use of ice, always wearing shoes, heel raises and stretching, follow this advice. As a pronated foot is common in children
with this problem, a discussion regarding the use of foot orthotics long term may be important. Strapping or tape is sometimes used during activity to limit the ankle joint range of motion. If the
symptoms are bad enough and not responding to these measures, medication to help with anti-inflammatory may be needed. In some cases the lower limb may need to be put in a cast for 2-6 weeks to give
it a good chance to heal. After the calcaneal apophysitis resolves, prevention with the use of stretching, good supportive shock absorbing shoe and heel raises are important to prevent it happening
One of the most important things to know about Sever's disease is that, with proper care, the condition usually goes away within 2 weeks to 2 months and does not cause any problems later in life. The
sooner Sever's disease is addressed, the quicker recovery is. Most kids can return to physical activity without any trouble once the pain and other symptoms go away. Although Sever's disease
generally heals quickly, it can recur if long-term measures are not taken to protect the heel during a child's growing years. One of the most important is to make sure that kids wear proper shoes.
Good quality, well-fitting shoes with shock-absorbent (padded) soles help to reduce pressure on the heel. The doctor may also recommend shoes with open backs, such as sandals or clogs, that do not
rub on the back of the heel. Shoes that are heavy or have high heels should be avoided. Other preventive measures include continued stretching exercises and icing of the affected heel after activity.
