At what age does Sever's disease commonly occur in males?

Sever's disease, also known as calcaneal apophysitis, is an overuse injury that affects the growth plate of the heel in children and adolescents. This condition is typically seen in physically active kids, especially those involved in sports that involve running and jumping.

This condition usually presents in males between the ages of 8 and 15 years, with a peak incidence around 11 years. The reason for this age range is closely related to the growth patterns of children, as it coincides with periods of rapid growth spurt where the heel's growth plate can become inflamed due to increased tension from the Achilles tendon.

The age of 11 years is significant as it often corresponds to those who are beginning to participate more heavily in organized sports, leading to increased physical activity and stress on the heel. Therefore, identifying this age helps healthcare providers recognize the likely onset of Sever's disease and advise accordingly on management and activity modifications.
