Sever?s disease (also known as calcaneal apophysitis) is a type of bone injury in which the growth plate in the lower back of the heel, where the Achilles tendon (the heel cord that attaches to the growth plate) attaches, becomes inflamed and causes pain. Sever?s disease is the most common cause of heel pain in children, especially those who exercise or play sports on a regular basis.
Your child may have pain along the edges of one or both heels during exercise. The pain usually goes away with rest, but may be worse in the morning. Your child's heel may also be slightly swollen and warm. The heel pain may be worse when your child climbs steps or stands on tiptoe. It may cause your child to limp.
Sharp pain will be present in the affected heel (or both heels), especially while running or walking. Pain can be heightened following activity. The area will be tender to the touch and usually becomes inflamed or reddened. It may also be painful to press on the heel with a finger from the back or to squeeze the sides together; the latter is particularly common. You might notice stiffness in some of the surrounding muscles, making regular movements more difficult to achieve. This and the pain can manifest physically in abnormal practices like tiptoeing or limping. In some cases a lump can be detected on the back of the heel, though it may be so small as to defy detection.
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. The doctor may order an x-ray because x-rays can confirm how mature the growth center is and if there are other sources of heel pain, such as a stress fracture or bone cyst. However, x-rays are not necessary to diagnose Sever?s disease, and it is not possible to make the diagnosis based on the x-ray alone.
Non Surgical Treatment
There are several things we can do to treat Sever?s disease and ease the discomfort. Special shoe inserts, such as heel pads or cups, can act as a shock absorber, decrease pressure on the heel bone and slightly elevate the heel to relieve the pain. Elastic wraps and compression stockings can help decrease any swelling and pain. We also show kids some specific stretches that can help stretch the calf muscles and tendons on the back of the leg to reduce stress on the heel. We might also recommend rest, applying ice, elevating the foot, and over-the-counter pain medication.
The chances of a child developing heel pain can be reduced by avoiding obesity. Choosing well-constructed, supportive shoes that are appropriate for the child?s activity. Avoiding or limiting wearing of cleated athletic shoes. Avoiding activity beyond a child?s ability.
