Calcaneal Apophysitis The TruthOverview
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).
Inflammation occurs at the insertion of the achilles tendon into the back of the heel due to a number of reasons. One or several of the following may cause the initiation of Sever?s disease. Rapid growth spurt. Tight calf muscles. Change in footwear (soccer boots / athletic shoes no heel). Excessive rolling in of feet. Poor warm up routine. Remember this condition usually settles as the growth plate fuses within 6-12 months.
The symptoms of Sever?s disease occur in the heel and the foot, and may worsen with activity. Pain and stiffness can occur in one or both heels. Symptoms can include. Swelling in the heel. Redness in the heel. Antalgic gait (such as limping). Foot pain or stiffness first thing in the morning or while walking. Pain that is worsened by squeezing the heel.
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
Reduce activity, avoid going barefoot, and cushion the child's heel with shock absorbency. It is very important that your child wear shoes with padded heel surfaces and shoes with good arch supports even when not participating in sports. A heel cup or soft pediatric shoe insert is very important to reduce the pull from the calf muscles on the growth plate and to increase shock absorption and reduce irritation. The use of an ice pack after activity for 20 minutes is often useful. Your health care provider may also prescribe anti-inflammatory drugs or custom orthotics.
Having Sever?s disease does not predispose children or teens to any other condition, nor is it a permanent problem. It is self-limiting, and when treated, the pain and other symptoms will abate within a few weeks. Once the growth plate has finished growing, Sever?s disease will resolve and won?t recur. It is important to continue to treat any underlying foot conditions and to avoid any long periods of inactivity.
