Overview
Sever?s disease is a condition occurring in pre-adolescents that causes pain, swelling and soreness in the heel bone, also known as the calcaneus. Sever?s disease causes pain on either side of and/or on the bottom of the heel. During a period of pre-adolescent development, the growing heel bone can be overused when the child is involved in a lot of running and jumping activities. Impact on the heel bone and repeated traction on the growing bone from the Achilles tendon can lead to swelling in the area.
Causes
With early puberty, the growth plate at the end of the heel develops, transforming cartilage cells into bone cells. This painful heel condition occurs during these growth spurts, when the heel bone grows more rapidly than the muscles and tendons of the leg. The discrepancy between rates of development causes excess pressure and tension to be placed upon the heel and it becomes less flexible. This condition affects active children the most. Due to the amount of exercise, more stress is placed upon the tendons which in turn causes more damage to the growth plate. The bone plates fully mature and harden by the time a child reaches the age of 15.
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
Sever?s disease can be diagnosed based on the symptoms your child has. Your child?s doctor will conduct a physical examination by squeezing different parts of your child?s foot to see if they cause any pain. An X-ray may be used to rule out other problems, such as a broken bone or fracture.
Non Surgical Treatment
Ice the heel(s) well after exercise (until the area is cold and numb!) Stretch hamstring and calf muscles 2-3 times daily (exercises below) REST when pain becomes persistent or moderate (even if it means skipping games or practices.) Anti-inflammatory medication such as ibuprofen. If symptoms persist, your child may need to see a physical therapist for additional exercises, and/or an orthopedist for othotics or temporary casting/crutches if pain is severe. Sever?s disease is self-recovering, meaning that it will go away on its own when the heels are rested or when the bone is through growing. The condition is not expected to create any long-term disability, and expected to subside in 2-8 weeks. However, pain can recur, for example at the start of a new sports season, several times if it is not taken care of.
Exercise
Exercises that help to stretch the calf muscles and hamstrings are effective at treating Sever's disease. An exercise known as foot curling, in which the foot is pointed away from the body, then curled toward the body in order to help stretch the muscles, has also proven to be very effective at treating Sever's disease. The curling exercise should be done in sets of 10 or 20 repetitions, and repeated several times throughout the day.
