Sever's disease or Calcaneal apophysitis is a condition that affects children between the ages of 10 and 13 years. It is characterized by pain in one or both heels with walking. During this phase of
life, growth of the bone is taking place at a faster rate than the tendons. Hence there is a relative shortening of the heel-cord compared to the leg bones. As a result, the tension the heel-cord
applies to the heel bone at its insertion is very great. Moreover, the heel cord is attached to a portion of the calcaneus (heel bone) that is still immature, consisting of a mixture of bone and
growing cartilage, called the calcaneal apophysis, which is prone to injury. Compounding to this is the fact that all these changes are happening in a very active child, prone to overuse. The end
result is therefore an overuse syndrome of injury and inflammation at the heel where the heel cord (Achilles Tendonitis) inserts into the heel bone (Calcaneal apophysitis).
Contraction of the calf muscles along with the rapid growth of the leg bone (tibia), decreases ankle motion and increases strain on the heel area. This puts strain on the Achilles tendon. Injury
results from repetitive pulling through the heel bone by the Achilles and the traction forces from the plantar fascia.
The most obvious sign of Sever's disease is pain or tenderness in one or both heels, usually at the back. The pain also might extend to the sides and bottom of the heel, ending near the arch of the
foot. A child also may have these related problems, swelling and redness in the heel, difficulty walking, discomfort or stiffness in the feet upon awaking, discomfort when the heel is squeezed on
both sides, an unusual walk, such as walking with a limp or on tiptoes to avoid putting pressure on the heel. Symptoms are usually worse during or after activity and get better with rest.
Sever's disease is based on the symptoms reported. To confirm the diagnosis, the clinician will examine the heels and ask about the child's activity level and participation in sports. They may also
squeeze the back part of the heel from both sides at the same time to see if doing so causes pain and also ask the child to stand on tiptoes to see if that position causes pain. There may be
tightness in the calf muscle, which contributes to tension on the heel. Symptoms are usually worse during or after activity and get better with rest. X-rays generally are not that helpful in
diagnosing Sever's disease, but they may be ordered to rule out other problems, such as fractures. Sever's disease cannot be seen on an X-ray.
Non Surgical Treatment
Initially, Sever?s Disease is treated with rest, anti-inflammatory medication and softer shoes. Ice followed by heat is a common practice and heel cup orthotics have worked wonders for our young
patients in the past. It can take anywhere from a few weeks to a year for these growth plates to naturally close - at which point Sever?s Disease disappears. Even though the condition does heal on
its own, athletes are encouraged to seek treatment, rather than push through the pain. Simply ?dealing with it? and continuing to play sports despite the injury could lead to an impaired gait, a
strained hip or a knee injury. Stretches to strengthen the leg muscles, leg compression wraps and over-the-counter acetaminophen or ibuprofen are also recommended treatments. In very rare cases, a
podiatrist may recommend wearing a cast for two to twelve weeks.
Sever's disease may be prevented by maintaining good joint and muscle flexibility in the years leading up to, and during, their growth spurts (eg girls 8 to 10, boys 10 to 12). Foot arch problems
such as flat feet should be addressed after the age of five if they don't appear to be self-correcting. If you are concerned, please ask your health practitioner. The most important factor is the
amount of weight-bearing exercise your child is currently performing. Finally, LISTEN To Your Child! If your child is suffering heel pain between the ages of 8 to 12, suspect Sever's disease until
proven otherwise. Seek the professional opinion of your foot practitioner regarding its diagnosis and subsequent management.
