Pain in the heel of a child's foot, typically brought on by some form of injury or trauma, is sometimes Sever's Disease. The disease often mimics Achilles tendonitis, an inflammation of the tendon attached to the back of the heel. A tight Achilles tendon may contribute to Sever's Disease by pulling excessively on the growth plate of the heel bone. This condition is most common in younger children and is frequently seen in the active soccer, football or baseball player. Sport shoes with cleats are also known to aggravate the condition. Treatment includes calf muscle stretching exercises, heel cushions in the shoes, and/or anti-inflammatory medications. Consult your physician before taking any medications.
Young athletes typically sustain the injury due to repeated stress caused by running and jumping. Partaking in any high speed sports can thus partly provoke the condition, such as football, rugby, basketball, hockey or track athletics. Crucially the injury is linked to overuse, so exercising with fatigued leg muscles, without a suitable warm up, or beginning a new strenuous physical activity are all risk factors. Placing excessive weight or pressure on the heel can also cause the injury. Another factor related to Sever's disease is overpronation, a biomechanical error that makes the foot roll too far inwards.
This is a condition that affects the cartilage growth plate and the separate island of growing bone on the back of the heel bone. This growth plate is called the physeal plate. The island of growing bone is called the apophysis. It has the insertion attachment of the Achilles tendon, and the attachment of the plantar fascia. This island of bone is under traction from both of these soft tissue tendon and tendon-like attachments.
Sever?s disease can be diagnosed based on the symptoms your child has. Your child?s doctor will conduct a physical examination by squeezing different parts of your child?s foot to see if they cause any pain. An X-ray may be used to rule out other problems, such as a broken bone or fracture.
Non Surgical Treatment
When the condition flares, it is treated with activity limitation, medication to reduce inflammation (such as ibuprofen [Advil] or naproxen [Aleve]), shoe inserts, heel lifts, cold packs, and sometimes casting when it becomes especially severe. Sever condition is generally a self-limited problem that usually improves within a year.
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. The disease may also take several years to stop, because it is often triggered by growing too fast. It is more common in boys, although occurs in girls as well. The average age of symptom onset is 9-11.
