The muscle group at the back of the lower leg is commonly called the calf. The calf comprises of 2 major muscles (known as the gastrocnemius and soleus) both of which insert into the heel bone via
the Achilles tendon. In people who have not yet reached skeletal maturity, a growth plate exists where the Achilles tendon inserts into the heel bone. This growth plate is primarily comprised of
cartilage. Every time the calf contracts, it pulls on the Achilles tendon which in turn pulls on the heel's growth plate. When this tension is too forceful or repetitive, irritation to the growth
plate may occur resulting in pain and sometimes an increased bony prominence at the back of the heel. This condition is called Severs disease. Severs disease is typically seen in children or
adolescents during periods of rapid growth. This is because muscles and tendons become tighter as bones become longer. As a result, more tension is placed on the heel's growth plate.
Sever disease is more common in children who do regular sports or exercise that puts pressure on the heels. Activities such as running and jumping can put stress on the tight muscles and
Acute pain, pain asscoiatied with Sever?s disease is usually felt in the heel when the child engages in physical activity such as walking, jumping and or running. Highly active - children who are
very active are among the most susceptible in experiencing Sever?s disease, because of the stress and tension placed on their feet.
Sever?s disease can be diagnosed based on your history and symptoms. Clinically, your physiotherapist will perform a "squeeze test" and some other tests to confirm the diagnosis. Some children suffer
Sever?s disease even though they do less exercise than other. This indicates that it is not just training volume that is at play. Foot and leg biomechanics are a predisposing factor. The main factors
thought to predispose a child to Sever?s disease include a decrease in ankle dorsiflexion, abnormal hind foot motion eg overpronation or supination, tight calf muscles, excessive weight-bearing
activities eg running.
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.
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
