Overview

Sever’s disease (calcaneal apophysitis) is a common cause of heel pain, particularly in physically active young people who are about to begin puberty. The cause is uncertain, but it is thought that the long calf bones of the leg grow faster than the surrounding muscle and soft tissue, causing the Achilles tendon to pull uncomfortably tight. Sever?s disease (sometimes called Sever disease) is a common cause of heel pain, particularly in the young and physically active. It usually develops just before puberty. Boys are slightly more prone to this condition than girls. Physiotherapy can help manage the symptoms of Sever?s disease so that the young person can continue to take part in physical activity. Another name for Sever?s disease is calcaneal apophysitis.

Causes

During the growth spurt of early puberty, the heel bone (also called the calcaneus) sometimes grows faster than the leg muscles and tendons. This can cause the muscles and tendons to become very tight and overstretched, making the heel less flexible and putting pressure on the growth plate. The Achilles tendon (also called the heel cord) is the strongest tendon that attaches to the growth plate in the heel. Over time, repeated stress (force or pressure) on the already tight Achilles tendon damages the growth plate, causing the swelling, tenderness, and pain of Sever’s disease. Such stress commonly results from physical activities and sports that involve running and jumping, especially those that take place on hard surfaces, such as track, basketball, soccer, and gymnastics.

Symptoms

Unilateral or bilateral heel pain. Heel pain during physical exercise, especially activities that require running or jumping. Increased pain level after exercise. A tender swelling or bulge on the heel that is painful on touch. Limping. Calf muscle stiffness first thing in the morning.

Diagnosis

Most often, a healthcare professional can diagnose Sever?s disease by taking a careful history and administering a few simple tests during the physical exam. A practitioner may squeeze the heel on either side; when this move produces pain, it may be a sign of Sever?s disease. The practitioner may also ask the child to stand on their tiptoes, because pain that occurs when standing in this position can also be an indication of Sever?s disease.

Non Surgical Treatment

The aims are to reduce trauma to the heel, allow rest/recovery and prevent recurrence. Most cases are successfully treated using physiotherapy and exercises, eg to stretch the gastrocnemius-soleus complex, to mobilise the ankle mortise, subtalar joint and medial forefoot. Soft orthotics or heel cups. Advice on suitable athletic footwear. Other modes of treatment are in severe cases, temporarily limiting activity such as running and jumping. Ice and non-steroidal anti-inflammatory drugs (NSAIDs), which can reduce pain. In very severe cases, a short period of immobilisation (eg 2-3 weeks in a case in mild equinus position) has been suggested.

Surgical Treatment

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.
