Calcaneal apophysitis (Sever's disease) in children
Calcaneal apophysitis (cal·ca·ne·al - apoph·y·si·tis), also called Sever’s disease, describes an inflammation (swelling) of the calcaneal apophysis (heel) growth plate, which causes heel pain.
What is calcaneal apophysitis (Sever's disease) in children?
Typically impacting young athletes, calcaneal apophysitis usually affects children between ages 8 and 14 years old, as the heel bone is not fully developed until age 14. The heel growth plate (area of growing tissue at the end of long bones) suffers damage due to repeated trauma. This is because the Achilles tendon (tendon that runs along the back of foot above the heel) pulls the apophysis during activities. It typically occurs in both heels, but can also occur in only one heel.
Sever's disease was first described by James Warren Sever, an American orthopedic physician, in 1912.
What are the signs and symptoms of calcaneal apophysitis (Sever's disease) in children?
Symptoms of calcaneal apophysitis can include:
Heel pain during sports
Heel pain on one or both sides
Heel swelling
Limping
Pain when the heel is squeezed
What are the causes of calcaneal apophysitis (Sever's disease) in children?
Calcaneal apophysitis can occur due to repeated trauma through the following:
Abnormal growth patterns where the bones grow faster than the soft tissue (muscles or tendons), which pull on the growth plate
Repeated running and jumping as the feet pound on hard surfaces (can occur in athletes who play basketball, soccer or track)
Additional strain from abnormal weight gain or obesity
Improperly fitted footwear or not enough support from shoes
Tight lower leg muscles, specifically in the calf and Achilles tendon
Flat feet or a high arch in the foot
