Overview
Sever’s disease involves a lesion to the heel that appears mostly as a result of excessively twisting the ankle. The injury is particularly prevalent in children over 10 and other younger athletes because the heel bone, muscles and tendons are still developing – the bone faster than the muscles – and the condition strikes a growing part of the bone called the calcaneal apophysis. In older people an injury of this sort generally results in a stress fracture.
Causes
There are usually two root causes of Sever?s disease that we?ve found that effect young athletes. Arches are not supported causing a dysfunctional run, jump, and landing. The calves (gastrocnemius and soleus muscles) are overworked, tight, and do not allow proper movement of foot which puts extreme pressure on the Achilles? tendon, in turn irritating the growth plate in the heel.
Symptoms
Sever’s disease usually develops gradually. The pain from Sever’s disease is often intermittent and localized to the area where the Achilles tendon attaches to the calcaneus. Swelling may be noted in this area. There can be tenderness on squeezing the calcaneus or pain when trying to stretch the calf muscles. Occasionally there is night pain. As Sever’s disease progresses there can be continuous pain.
Diagnosis
To diagnose the cause of the child?s heel pain and rule out other more serious conditions, the foot and ankle surgeon obtains a thorough medical history and asks questions about recent activities. The surgeon will also examine the child?s foot and leg. X-rays are often used to evaluate the condition. Other advanced imaging studies and laboratory tests may also be ordered.
Non Surgical Treatment
The disease itself is self limiting and will resolve regardless of treatment once the growth plate has fully closed. Depending on the age of the youth at onset this could be a problem for many years. Treatment has always been aimed at managing the pain as well as the inflammation. This is done with the rest, ice, non steroidal anti-inflammatories like ibuprofen, stretching, taping, heel cups, heel lifts and orthotics. In severe cases, cast or walking boot immobilization is used. Each of these have differing levels of efficacy but in my experience orthotics are the golden treatment or the silver bullet. I am not talking about your run of the mill over the counter Dr. Scholls shoe insert. These definitely have their place in the world but not here. Custom molded orthotics made from a mold taken of the youths foot will provide the necessary control and support to stop the pain cycle. We can safely report over 85% of patients who are able to get back to sports and other activities as long as they wear the orthotics in supportive shoes as directed.
Exercise
For children with Sever’s disease, it is important to habitually perform exercises to stretch the hamstrings, calf muscles, and the tendons on the back of the leg. Stretching should be performed 2-3 times a day. Each stretch should be performed for 20 seconds, and both legs should be stretched, even if the pain is only in one heel. Heel cups or an inner shoe heel lifts are often recommended for patient suffering from Sever’s disease. Wearing running shoes with built in heel cups can also decrease the symptoms because they can help soften the impact on the heel when walking, running, or standing.
