The calcaneal apophysis is a growth center where the Achilles tendon and the plantar fascia attach to the heel. It first appears in children aged 7 to 8 years. By ages 12 to 14 years the growth center matures and fuses to the heel bone. Injuries can occur from excessive tension on the Achilles tendon and the plantar fascia, or from direct impact on the heel. Excessive stress on this growth center can cause irritation of the heel, also called Sever?s disease.
This condition is more common in boys than girls. It generally presents between the ages of 9-14 and peaks between ages 10-12 years. This injury can reoccur up until the age of 17, when the growth plate of the calcaneous generally closes. These types of injuries will commonly occur during periods of rapid growth. Sever?s Disease occurs more frequently in child with flat feet, but all children with flat feet will not get Sever?s.
The most common symptoms of Sever?s involves pain or tenderness in one or both heels. This pain usually occurs at the back of the heel, but can also extend to the sides and bottom of the heel. A child with Sever?s may also have these common problems, Heel pain with limping, especially after running. Difficulty walking, Discomfort or stiffness in the feet upon awaking. Swelling and redness in the heel, Symptoms are usually worse during or after activity and get better with rest.
All medical diagnosis should be made by taking a full history, examining the patient then performing investigations. The problem usually occurs in boys who are going through or have just gone through a growth spurt; one or both heels may be affected. Initially the pain may be intermittent occurring only during or after exercise. As the problem gets worse, pain may be present most of the time. There may be swelling over the back of the heel and this area is painful if touched or knocked. On examination the patient often has flat feet, very tight legs muscles especially the gastrocnemius.
Non Surgical Treatment
The doctor will talk with you about the best treatment plan for your child. As instructed, your child will Ice the heel 3-4 times a day for 15-20 minutes at a time. Use an ice pack or bag of frozen peas, or something similar. Never put ice directly on your child's skin. A thin cloth or towel should be between your child?s skin and the ice pack. Take anti-inflammatory medication, such as ibuprofen, as directed. Decrease the amount of running and jumping he or she does. Stretch the heels and calves, as instructed by the doctor. Regular stretching can help prevent Sever?s from coming back. Use a ?heel cup? or a cushioned shoe insert that takes pressure off the heel. In some cases, a cast is placed on the foot and worn for several weeks.
