Sever's Disease (Calcaneal Aphophysitis) is not a disease, but a repetitious strain injury common in children between the ages of 8 and 14 years old. It is a common cause of heel pain, particularly in the very active child. Patients with Sever's disease complain of pain in the bottom surface region of the back of the heel. This is where the growth plate is located, and is not fully developed or calcified in a child's foot.
Sever condition is caused by sprain injury where the Achilles tendon attaches to the calcaneus bone at the back of the heel. Sever condition occurs in adolescent or older children, particularly active boys. It can be very painful. It is one of those conditions commonly referred to as "growing pains." Patients are evaluated for signs of conditions that can mimic Sever condition, such as ankylosing spondylitis and other forms of arthritis. Usually Sever condition is self-limited; that is, it disappears as the child ages.
Pain is usually felt at the back of the heel and around the sides of the heel. If you squeeze the back of the heel from both sides simultaneously and pain is experienced Sever?s disease is more than likely present.
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.
