Sever?s disease, or calcaneal apophysitis, is a common cause of heel pain in patients whose bones are still growing; however, it is not really a disease. The pain is caused by stress at the point
where the Achilles tendon meets tissue called the plantar fascia on the growth plate (apophysis) of the heel bone (calcaneus).
Sever's affects boys more often than girls. Boys are most often affected at age 12, and girls at age 9, though Sever's is typically seen in children and adolescents between the ages of 7 and
There is no specific known cause of Sever?s disease. However, there are several common factors associated with the condition including. Tight calf muscles. Pronated foot type (rolled in towards the
ankle). Children who are heavier. Puberty/growth spurts. External factors, e.g. hard surfaces or poor footwear. Increase in physical activity levels.
Pain is usually felt at the back and side of the heel bone. Sometimes there may be pain at the bottom of the heel. The pain is usually relieved when the child is not active and becomes painful with
sport. Squeezing the sides of the heel bone is often painful. Running and jumping make the symptoms worse. One or both heels can be affected. In more severe cases, the child may be limping.
A doctor can usually tell that a child has Sever's disease based on the symptoms reported. To confirm the diagnosis, the doctor will probably examine the heels and ask about the child's activity
level and participation in sports. The doctor might also use the squeeze test, squeezing the back part of the heel from both sides at the same time to see if doing so causes pain. The doctor might
also ask the child to stand on tiptoes to see if that position causes pain. Although imaging tests such as X-rays generally are not that helpful in diagnosing Sever's disease, some doctors order them
to rule out other problems, such as fractures. Sever's disease cannot be seen on an X-ray.
Non Surgical Treatment
Initially, treatment will consist of resting from activity, ice and anti-inflammatory medications to reduce the pain. Your physiotherapist may also use a variety of pain reducing techniques such as
soft tissue massage or joint mobilisations. They may recommend taping to unload the area of pain, heel cups or wedge inserts into the bottom of your shoe. Also in the initial phase we may also refer
you to podiatry for orthotics and/or further footwear recommendations. It is also ideal in the first instance to start stretching your calf muscles and achilles. This initial phase typically lasts
for 1-2 weeks. During this time your physiotherapist will guide you on appropriate levels of activity- they may recommend you rest from impact type activities during this phase, and will guide you on
the best program to return to your sport without any further injury.
