Although the name might sound pretty frightening, Sever's disease is really a common heel injury that occurs in kids. It can be painful, but is only temporary and has no long-term effects. Sever's
disease, also called calcaneal apophysitis, is a painful bone disorder that results from inflammation (swelling) of the growth plate in the heel. A growth plate, also called an epiphyseal plate, is
an area at the end of a developing bone where cartilage cells change over time into bone cells. As this occurs, the growth plates expand and unite, which is how bones grow. Sever's disease is a
common cause of heel pain in growing kids, especially those who are physically active. It usually occurs during the growth spurt of adolescence, the approximately 2-year period in early puberty when
kids grow most rapidly. This growth spurt can begin any time between the ages of 8 and 13 for girls and 10 and 15 for boys. Sever's disease rarely occurs in older teens because the back of the heel
usually finishes growing by the age of 15, when the growth plate hardens and the growing bones fuse together into mature bone. Sever's disease is similar to Osgood-Schlatter disease, a condition that
affects the bones in the knees.
Your child is most at risk for this condition when he or she is in the early part of the growth spurt in early puberty. Sever's disease is most common in physically active girls 8 years to 10 years
of age and in physically active boys 10 years to 12 years of age. Soccer players and gymnasts often get Sever's disease, but children who do any running or jumping activity may also be at an
increased risk. Sever's disease rarely occurs in older teenagers because the back of the heel has typically finished growing by 15 years of age.
Sever's disease usually develops gradually. The pain from Sever's disease is often intermittent and localized to the area where the Achilles tendon attaches to the calcaneus. Swelling may be noted in
this area. There can be tenderness on squeezing the calcaneus or pain when trying to stretch the calf muscles. Occasionally there is night pain. As Sever's disease progresses there can be continuous
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
Non Surgical Treatment
The primary method of treating Sever?s disease is taking time off from sports and other physical activities to alleviate the pressure on the heel bone. During the healing period, your child?s doctor
may also recommend physical therapy or any type of exercise that involves stretching and strengthen leg muscles and tendons. Wrapping ice in a towel and placing it under the child?s heel will also
help to alleviate and reduce pain and swelling.
