Sever’s disease is not essentially a disease, but a repetitious strain injury predominantly in active children 9-14 years old.
- Pain at rear of heel (calcaneous bone) during adolescence, usually after a growth spurt and high levels of sprinting types of activities
Sever’s Disease (Calcaneal Apophysitis) is pain at the back of the heel at the growth plate where bone has not yet fully developed and calcified. The Achilles tendon and plantar fascia attach to the growing bone which then undergoes a lot of pulling forces from these structures during weight bearing activities.
- Striking the heel on the ground places stress through the growth plate in addition to the pulling forces of the fascia and Achilles
- If the Achilles tendon is tight due to either insufficient length of the calf muscles or decreased joint movement. it will pull at the attachment at the calcaneus (heel bone)
- Biomechanical problems of the lower limb
- Repetitous actions like running, jumping, side stepping sports such as football, hockey, athletics, basketball, tennis etc. It can also occur in children with low activity levels as well.
