Sever?s disease, also known as calcaneal apophysitis, is a common heel problem affecting children. This heel bone disorder is often painful, though it?s usually temporary and causes no long-term
health effects. With Sever?s disease, the Achilles tendon repeatedly pulls on the heel?s growth plate, causing microtrauma (i.e. microfractures), inflammation, and swelling in the affected area.
Sever?s disease is similar to Osgood-Schlatter disease, which affects the knee. Inappropriate footwear may be a contributing factor in the onset of this condition.
Severs disease is often associated with a rapid growth spurt. As the bones get longer, the muscles and tendons become tighter as they cannot keep up with the bone growth. The point at which the
achilles tendon attaches to the heel becomes inflamed and the bone starts to crumble (a lot like osgood schlatters disease of the knee). Tight calf muscles may contribute as the range of motion at
the ankle is reduced resulting in more strain on the achilles tendon. Sever's disease is the second most common injury of this type which is known as an apophysitis.
The most common symptoms of Sever?s involves pain or tenderness in one or both heels. This pain usually occurs at the back of the heel, but can also extend to the sides and bottom of the heel. A
child with Sever?s may also have these common problems. Heel pain with limping, especially after running. Difficulty walking. Discomfort or stiffness in the feet upon awaking. Swelling and redness in
the heel. Symptoms are usually worse during or after activity and get better with rest.
A Podiatrist can easily evaluate your child?s feet, to identify if a problem exists. Through testing the muscular flexibility. If there is a problem, a treatment plan can be create to address the
issue. At the initial treatment to control movement or to support the area we may use temporary padding and strapping and depending on how successful the treatment is, a long-term treatment plan will
be arranged. This long-term treatment plan may or may not involve heel raises, foot supports, muscle strengthening and or stretching.
Non Surgical Treatment
Treatment aim is to lessen the load on the insertion of the Achilles tendon, along with pain relief if necessary. This can be achieved by modifying/reducing activity levels. Shoe inserts or heel
raises. Calf stretches. Avoiding barefoot walking. Strapping or taping the foot to reduce movement. Orthotic therapy if due to biomechanical causes. Other treatment includes icing of the painful area
to reduce swelling, pain medication if necessary and immobilisation of the affected limb in severe or long standing cases.
Sever?s disease is self-recovering, meaning that it will go away on its own when the foot is used less or when the bone is through growing. The condition is not expected to create any long-term
disability, and expected to subside in 2-8 weeks. Some orthopedic surgeons will put the affected foot in a cast to immobilize it. While symptoms can resolve quickly, they can recur. Sever's disease
is more common in boys than girls the average age of symptom onset is nine to eleven years.
