Sever?s disease is a painful condition of the heel affecting children, usually at the beginning of the growth spurt in early puberty. It is caused by inflammation at the growth plate at the back of the heel, adjacent to the Achilles tendon attachment. This is one of the most common causes of heel pain in school-aged children. Physically active children aged between eight and fourteen years old are most at risk of developing pain from Sever?s disease. It is common among children involved in soccer, little athletics, gymnastics, basketball and netball but can affect children involved in any running or jumping activity. Boys seem to be more commonly affected than girls.
Sever?s disease is directly related to overuse of the bone and tendons in the heel. This can come from playing sports or anything that involves a lot of heel movement. It can be associated with starting a new sport, or the start of a new season. Children who are going through adolescence are also at risk of getting it because the heel bone grows quicker than the leg. Too much weight bearing on the heel can also cause it, as can excessive traction since the bones and tendons are still developing. It occurs more commonly in children who over-pronate, and involves both heels in more than half of patients.
Symptoms include complaints of pain or tenderness in the heel (or heels), discomfort when heel is squeezed, limping, and more severe pain after walking, running or playing sports. Sever?s disease is directly related to overuse of the bone and tendons in the heel. This can come from playing sports or anything that involves lots of heel movements and hard shoes such as cleats. It can be associated with starting a new sport, or the start of a new season. It occurs more commonly in children who pronate (feet roll inward), and involves both heels in more than half of patients.
Sever?s disease is diagnosed based on a doctor?s physical examination of the lower leg, ankle, and foot. If the diagnosis is in question, the doctor may order x-rays or an MRI to determine if there are other injuries that may be causing the heel pain.
Non Surgical Treatment
Treatment may consist of one or more of the following. Elevating the heel. Stretching hamstring and calf muscles 2-3 times daily. Using R.I.C.E. (Rest, Ice, Compression, Elevation). Foot orthotics. Medication. Physical therapy. Icing daily (morning). Heating therapy. Open back shoe are best and avoid high heel shoe. The Strickland Protocol has shown a positive response in patients with a mean return to sport in less than 3 weeks. Further research into the anatomical and biomechanical responses of this protocol are currently being undertaken.
As with all overuse injuries, it is important to warm up sufficiently before you exercise and warm down afterwards. You should build up any alterations in the intensity of your training gradually, and never continue exercising with weakened or fatigued muscles. Replace any worn or tattered shoes, as in this condition they become useless for absorbing shock and protecting the feet.
