What Are The Causes Of Calcaneal Apophysitis?

Overview

Severs Disease, otherwise known as Osteochondroses, is the most common injury of its kind to affect children?s feet. The condition predominately affects children between the ages of 8 - 15 and causes pain at the back of the heel where the Achilles tendon inserts onto the bone. Children will complain of pain during activity and may have difficulty walking.

Causes

Sever's disease can result from standing too long, which puts constant pressure on the heel. Poor-fitting shoes can contribute to the condition by not providing enough support or padding for the feet or by rubbing against the back of the heel. Although Sever's disease can occur in any child, these conditions increase the chances of it happening. Pronated foot (a foot that rolls in at the ankle when walking), which causes tightness and twisting of the Achilles tendon, thus increasing its pull on the heel's growth plate, flat or high arch, which affects the angle of the heel within the foot, causing tightness and shortening of the Achilles tendon, short leg syndrome (one leg is shorter than the other), which causes the foot on the short leg to bend downward to reach the ground, pulling on the Achilles tendon, overweight or obesity, which puts weight-related pressure on the growth plate

Symptoms

Symptoms of calcaneal apophysitis may include Pain in the back or bottom of the heel, Limping, Walking on toes, Difficulty running, jumping, or participating in usual activities or sports, Pain when the sides of the heel are squeezed.

Diagnosis

Low-grade inflammation of the calcaneal apophysis cannot be seen on x-ray. Therefore, although x-rays are often done to rule out bony injuries in children with Sever's disease these x-rays are usually normal. Advanced Sever's disease can be seen on x-ray but usually the problem is treated before it reaches this point. Other diagnostic tests, such as bone scans or MRI's, are not usually required in typical cases of Sever's disease. These, or other tests, may be required to rule out other conditions, such as stress fractures of the calcaneus or other bony abnormalities that can mimic Severs disease.

Non Surgical Treatment

Traditional treatment involved simply telling children that they can?t play sport for a year. This is not popular for children or parents and abstaining from sport leads to other problems when wanting to return. Treatments focus on improving foot and lower limb function with footwear selection, heel raises, calf stretching, prescription orthoses, run technique training and training modifications. This results in a reduced load through the growth plate and the child can perform more activity before the growth plate becomes inflamed. Rest will always reduce the Sever?s disease symptoms, however this is always the last option.

Recovery

One of the most important things to know about Sever's disease is that, with proper care, the condition usually goes away within 2 weeks to 2 months and does not cause any problems later in life. The sooner Sever's disease is addressed, the quicker recovery is. Most kids can return to physical activity without any trouble once the pain and other symptoms go away.
