Diagnosing Calcaneal Apophysitis
Overview
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.
Causes
The foot is one of the first body parts to grow to full size. During the time of growth, bones grow faster than muscles and tendons. This results in the muscles and tendons becoming tight. The strongest tendon that attaches to the heel is the Achilles Tendon. It attaches to the back of the heel at the site of the growth plate, and during sports activities it pulls with great force on the growth plate. If this pull by the tight Achilles Tendon (calf muscle) continues for long periods of time, the growth plate may become inflamed and painful. If exertive activities continue, Sever's Disease may result.
Symptoms
The pain associated with Sever's disease is usually felt along the back of the heel and becomes worse when running or walking. In some children, the pain is so severe they may limp when walking. One of the diagnostic tests for Sever's disease is the "squeeze test". Squeezing both sides of the heel together will produce immediate discomfort. Many children feel pain immediately upon waking and may have calf muscle stiffness in the morning.
Diagnosis
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
Heel pain, unlike the heel spurs, that occur in adults is very uncommon in children. Of those children who do get heel pain, by far the most common cause is a disturbance to the growing area at the back of the heel bone (calcaneus) where the strong achilles tendon attaches to it. This is known as Sever's disease or calcaneal apophysitis (inflammation of the growth plate). It is most common between the ages of 10 to 14 years of age. These are one of several different 'osteochondroses' that can occur in other parts of the body, such as at the knee (Osgood-Schlatters Disease).
Exercise
For children with Sever's disease, it is important to habitually perform exercises to stretch the hamstrings, calf muscles, and the tendons on the back of the leg. Stretching should be performed 2-3 times a day. Each stretch should be performed for 20 seconds, and both legs should be stretched, even if the pain is only in one heel. Heel cups or an inner shoe heel lifts are often recommended for patient suffering from Sever's disease. Wearing running shoes with built in heel cups can also decrease the symptoms because they can help soften the impact on the heel when walking, running, or standing.
