Sever's disease occurs in children when the growth plate (which is the growing part of the heel) is injured. The foot is one of the first body parts to grow to full size. This usually occurs in early puberty. During this time, bones often grow faster than muscles and tendons. As a result, muscles and tendons become tight. The heel area is less flexible. During weight-bearing activity (activity performed while standing), the tight heel tendons may put too much pressure at the back of the heel (where the Achilles tendon attaches). This can injure the heel and cause Sever's disease.
What is Sever's disease?
When is my child most at risk for Sever's disease?
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 to 10 years old and in physically active boys 10 to 12 years old. 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 the age of 15.
