What Causes Severs Disease?

Overview

Sever's Disease is one of the most common causes of heel pain in active adolescents. Hip stability is restored using a non-surgical positioning device. Symptoms of Sever's disease are relieved through a combination of conservative treatment options and preventative measures can be taken to decrease the risk of developing the condition.

Causes

The foot is one of the first body parts to grow to full size. During the time of growth, bones grow faster than muscles and tendons. This results in the muscles and tendons becoming tight. The strongest tendon that attaches to the heel is the Achilles Tendon. It attaches to the back of the heel at the site of the growth plate, and during sports activities it pulls with great force on the growth plate. If this pull by the tight Achilles Tendon (calf muscle) continues for long periods of time, the growth plate may become inflamed and painful. If exertive activities continue, Sever's Disease may result.

Symptoms

If your child has any of the following symptoms, call your pediatrician for an evaluation. Heel pain that begins after starting a new sports season or a new sport. Walking with a limp or on tiptoes. Pain that increases with running or jumping. Heel tendon that feels tight. Pain when you squeeze the child's heel near the back. Pain in one or both heels.

Diagnosis

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

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.

Exercise

Stretching exercises can help. It is important that your child performs exercises to stretch the hamstring and calf muscles, and the tendons on the back of the leg. The child should do these stretches 2 or 3 times a day. Each stretch should be held for about 20 seconds. Both legs should be stretched, even if the pain is only in 1 heel. Your child also needs to do exercises to strengthen the muscles on the front of the shin. To do this, your child should sit on the floor, keeping his or her hurt leg straight. One end of a bungee cord or piece of rubber tubing is hooked around a table leg. The other end is hitched around the child's toes. The child then scoots back just far enough to stretch the cord. Next, the child slowly bends the foot toward his or her body. When the child cannot bend the foot any closer, he or she slowly points the foot in the opposite direction (toward the table). This exercise (15 repetitions of "foot curling") should be done about 3 times. The child should do this exercise routine a few times daily.
