Overview

What Is Calcaneal Apophysitis? Calcaneal apophysitis is a painful inflammation of the heel?s growth plate. It typically affects children between the ages of 8 and 14 years old, because the heel bone (calcaneus) is not fully developed until at least age 14. Until then, new bone is forming at the growth plate (physis), a weak area located at the back of the heel. When there is too much repetitive stress on the growth plate, inflammation can develop. Calcaneal apophysitis is also called Sever?s disease, although it is not a true ?disease.? It is the most common cause of heel pain in children, and can occur in one or both feet. Heel pain in children differs from the most common type of heel pain experienced by adults. While heel pain in adults usually subsides after a period of walking, pediatric heel pain generally doesn?t improve in this manner. In fact, walking typically makes the pain worse.

Causes

There are several factors which may increase the likelihood of developing this condition. These need to be assessed and corrected with direction from a physiotherapist to ensure an optimal outcome. Some of these factors include inappropriate footwear, calf tightness and/or weakness, joint stiffness (particularly the foot and ankle), poor lower limb biomechanics, inappropriate or excessive training, inadequate recovery periods from training or activity, inappropriate training surfaces, inadequate warm up, poor core stability, a lack of lower limb strength and stability, poor proprioception or balance, rapid growth and age.

Symptoms

On examination, the typical signs are tenderness on palpation of the heel, particularly on deep palpation at the Achilles tendon insertion. Pain on dorsiflexion of the ankle, particularly when doing active toe raises; forced dorsiflexion of the ankle is also uncomfortable. Swelling of the heel, usually mild. Calcaneal enlargement, in long-standing cases.

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

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.

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.
