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.
Severs disease is often associated with a rapid growth spurt. As the bones get longer, the muscles and tendons become tighter as they cannot keep up with the bone growth. The point at which the achilles tendon attaches to the heel becomes inflamed and the bone starts to crumble (a lot like osgood schlatters disease of the knee). Tight calf muscles may contribute as the range of motion at the ankle is reduced resulting in more strain on the achilles tendon. Sever's disease is the second most common injury of this type which is known as an apophysitis.
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.
Sever disease is most often diagnosed clinically, and radiographic evaluation is believed to be unnecessary by many physicians, but if a diagnosis of calcaneal apophysitis is made without obtaining radiographs, a lesion requiring more aggressive treatment could be missed. Foot radiographs are usually normal and the radiologic identification of calcaneal apophysitis without the absence of clinical information was not reliable.
Non Surgical Treatment
Orthotics, The orthotics prescribed are made to align the foot in its correct foot posture. This will reduce stress and force at the site of the growth plate of the heel bone. Rest and Ice the heel 20 minutes before and after sporting activity. Calf muscle stretching exercises.
