Pain in the heel of a child's foot, typically brought on by some form of injury or trauma, is sometimes Sever's Disease. The disease often mimics Achilles tendonitis, an inflammation of the tendon attached to the back of the heel. A tight Achilles tendon may contribute to Sever's Disease by pulling excessively on the growth plate of the heel bone. This condition is most common in younger children and is frequently seen in the active soccer, football or baseball player. Sport shoes with cleats are also known to aggravate the condition. Treatment includes calf muscle stretching exercises, heel cushions in the shoes, and/or anti-inflammatory medications. Consult your physician before taking any medications.
Having flatfeet or very pronated feet can make one prone to Sever's disease. But also patient?s that have a very high arch foot structure tend to have a very high shock and high impact heel strike. This also puts extra stress on the heel and apophysis.
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.
A doctor or other health professional such as a physiotherapist can diagnose Sever?s disease by asking the young person to describe their symptoms and by conducting a physical examination. In some instances, an x-ray may be necessary to rule out other causes of heel pain, such as heel fractures. Sever?s disease does not show on an x-ray because the damage is in the cartilage.
Non Surgical Treatment
Treatment is primarily directed towards reducing the amount of stress to the heel. Often a heel lift, is placed in the shoe to reduce the pull of the Achilles tendon on the apophysis. Gel or cushioned heel cups may also be helpful in reducing micro trauma to the heel. Orthotic control may also be indicated when a pathologic condition exists in the foot that may be contributing to the increased heel stress. Occasionally, it becomes necessary for adequate healing, to rest the area completely. This can be accomplished either by complete elimination of all strenuous activities, or by using a walking cast or crutches. Often simply reducing activity levels is adequate. Your physician will discuss the best treatment plan with you and your child.
