Sever’s disease is a painful irritation in the heel bone of the foot. It is the most common cause of heel pain in children and teens. Sever?s disease is also called calcaneal apophysitis.
A big tendon called the Achilles tendon joins the calf muscle at the back of the leg to the heel. Sever?s disease is thought to occur because of a mismatch in growth of the calf bones to the calf muscle and Achilles tendon. If the bones grow faster than the muscles, the Achilles tendon that attaches the muscle to the heel gets tight. At the same time, until the cartilage of the calcaneum is ossified (turned into bone), it is a potential weak spot. The tight calf muscle and Achilles tendon cause a traction injury on this weak spot, resulting in inflammation and pain. Sever?s disease most commonly affects boys aged ten to 12 years and girls aged nine to 11 years, when growth spurts are beginning. Sever?s disease heals itself with time, so it is known as ?self-limiting?. There is no evidence to suggest that Sever?s disease causes any long-term problems or complications.
Sever?s is recognized by pain in the back and lower regions of the heel. It usually starts during or immediately following the child’s growth spurt, and/or in very active individuals. The child will usually have pain during or following participation in sport, and will often be seen limping off the field or court. Symptoms of Sever’s include painful heel, no swelling or warmth, night pain is absent, pain is worse with increased activity, pain which is usually relieved by rest. Children often hobble or limp from the sports field.
This can include physical examination and x-ray evaluation. X-rays may show some increased density or sclerosis of the apophysis (island of bone on the back of the heel). This problem may be on one side or bilateral.
Non Surgical Treatment
A doctor, sports therapist or physiotherapist can apply a plaster cast or boot if the child is in severe pain. This may be worn for a few days or even weeks and should give relief of pain for a while. Carry out a full biomechanical assessment. This may help to determine if any foot biomechanics issues are contributing to the condition. Orthotics or insoles can be prescribed to help correct over pronation or other biomechanics issues. Prescribe anti-inflammatory medication such as ibuprofen to reduce pain and inflammation. This will not be prescribed if asthma the child has asthma. In persistent cases X-rays may be taken but this is not usual. A doctor, sports therapist or physiotherapist will NOT give a steroid injection or operate as these are not suitable treatment options. The condition will usually settle within 6 months, although it can persist for longer.
The surgeon may select one or more of the following options to treat calcaneal apophysitis. Reduce activity. The child needs to reduce or stop any activity that causes pain. Support the heel. Temporary shoe inserts or custom orthotic devices may provide support for the heel. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation. Physical therapy. Stretching or physical therapy modalities are sometimes used to promote healing of the inflamed issue. Immobilization. In some severe cases of pediatric heel pain, a cast may be used to promote healing while keeping the foot and ankle totally immobile. Often heel pain in children returns after it has been treated because the heel bone is still growing. Recurrence of heel pain may be a sign of calcaneal apophysitis, or it may indicate a different problem. If your child has a repeat bout of heel pain, be sure to make an appointment with your foot and ankle surgeon.
