Overview
Sever?s Disease (calcaneal aphophysitis) is not really a disease, but more a repetitious strain injury. This is the most common cause of kids heel pain seen at Podiatry Care. Active children in football, soccer, basketball, netball and tennis with this type of foot pain complain of pain in the region of the heel bone particularly after exercise. In severe cases, children will complain of pain during exercise as well. It is a frequent cause of heel pain in children, particularly in the very active child. It is most often seen in children between the ages of 8 to 15 years as the growth plate is not fully developed or calcified at this time.
Causes
There are many biomechanical factors that predispose a young athlete to calcaneal apophysitis. The majority of patients will present with an ankle equinus deformity, which ultimately exerts an increased pulling force to the Achilles insertion and non-ossified apophysis. Furthermore, patients may present with hyperpronation of the rearfoot. This allows more of a ?teeter-totter? effect or lack of motion control on the frontal plane of the calcaneus.
Symptoms
The most prominent symptom of Sever's disease is heel pain which is usually aggravated by physical activity such as walking, running or jumping. The pain is localised to the posterior and plantar side of the heel over the calcaneal apophysis. Sometimes, the pain may be so severe that it may cause limping and interfere with physical performance in sports. External appearance of the heel is almost always normal, and signs of local disease such as edema, erythema (redness) are absent. The main diagnostic tool is pain on medial- lateral compression of the calcaneus in the area of growth plate, so called squeeze test. Foot radiographs are usually normal. Therefore the diagnosis of Sever's disease is primarily clinical.
Diagnosis
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
Once diagnosed, there is a list of treatment options available to begin the recovery process. Unfortunately due to the nature of the condition it will often be a reoccurring condition until closure of the growth plates of the heel and elongation of the soft tissue structures. However with appropriate education, correct management of symptoms and prevention strategies, Severs disease can be well managed by the individual and their parents.
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.
