During AGS, and in specific reference to Sever?s disease, the heel bone grows faster than the Achilles tendon, resulting in an extremely tight Achilles tendon. Because the foot is one of the first parts of the body to grow to full size, and because the heel is not a very flexible area, it is especially susceptible to injury. The Achilles tendon (also called the heel cord) is the strongest tendon that attaches to the growth plate in the heel. Over time, repeated stress (such as impact activities) on the tight Achilles tendon causes the tendon to pull on and damage the growth plate in the heel, resulting in swelling, tenderness, and pain.
During the growth spurt of early puberty, the heel bone (also called the calcaneus) sometimes grows faster than the leg muscles and tendons. This can cause the muscles and tendons to become very tight and overstretched, making the heel less flexible and putting pressure on the growth plate. The Achilles tendon (also called the heel cord) is the strongest tendon that attaches to the growth plate in the heel. Over time, repeated stress (force or pressure) on the already tight Achilles tendon damages the growth plate, causing the swelling, tenderness, and pain of Sever's disease. Such stress commonly results from physical activities and sports that involve running and jumping, especially those that take place on hard surfaces, such as track, basketball, soccer, and gymnastics.
The symptoms of Sever?s disease occur in the heel and the foot, and may worsen with activity. Pain and stiffness can occur in one or both heels. Symptoms can include. Swelling in the heel. Redness in the heel. Antalgic gait (such as limping). Foot pain or stiffness first thing in the morning or while walking. Pain that is worsened by squeezing the heel.
This can include physical examination and x-ray evaluation. X-rays may show some increased density or sclerosis of the apophysis (island of bone on the back of the heel). This problem may be on one side or bilateral.
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.
Recovery time will vary from patient to patient. Age, health, previous injuries, and severity of symptoms will affect recovery time. Your compliance with the stretching program and the other recommendations made by your doctor will also determine your healing time. Heel pain often completely resolves after a child?s heel bone has stopped its period of growth.
