Sever's disease, also known as calcaneal apophysitis, is a medical condition that causes heel pain in one or both feet of children during the period when their feet are growing. Sever's disease occurs most commonly in boys and girls between the ages of 8 and 14 years of age. Sever's disease occurs when the part of the child's heel known as the growth plate, or the calcaneal epiphysis, an area attached to the Achilles tendon, suffers an injury or when the muscles and tendons of the growing foot do not keep pace with bone growth. The result is constant pain experienced at the back of the heel and the inability to put any weight on the heel, forcing the child to bear weight on their toes while walking. A toe gait develops in which the child must change the way they walk to avoid placing weight on the painful heel, a position that can lead to other developmental problems.
At birth, most of our foot bones are still made of cartilage, which ossifies (becomes bony) over the first few years of life. At the back of the heel, there is a growth plate that is attached to the main body of the heel bone by a cartilaginous join. At about the age of 14-15 years, this area of cartilage between the growth plate and the heel bone ossifies, fusing the area to the heel. Sever?s disease occurs when there is too much motion or strain across the growth plate, resulting in this area becoming inflamed and painful.
Pain in the lower calf and heel area which may be worse when applying pressure either side. Pain worse on activity especially those involving running or jumping. In severe cases this may cause the child to limp when walking. One or both heels affected.
A physical exam of the heel will show tenderness over the back of the heel but not in the Achilles tendon or plantar fascia. There may be tightness in the calf muscle, which contributes to tension on the heel. The tendons in the heel get stretched more in patients with flat feet. There is greater impact force on the heels of athletes with a high-arched, rigid foot.
Non Surgical Treatment
Sever disease is heel pain in children. This pain is caused by inflammation of the heel growth plate. The growth plate is the area where the bone grows. It is located on the lower back part of the heel.
Sever?s disease may be prevented by maintaining good flexibility while your child is growing. The stretching exercises mentioned here can lower your child?s risk for injuries during the growth spurt. Good-quality shoes with firm support and a shock-absorbent sole will help. Your child should avoid excessive running on hard surfaces. If your child has already recovered from Sever?s disease, stretching and putting ice on the heel after activity will help keep your child from getting this condition again.
