Sever’s Disease, otherwise known as calcaneal apophysitis is an inflammation of the growth plate in the heel of growing children, typically adolescents. The condition presents as pain in the heel and is caused by repetitive stress to the heel and is thus particularly common in active children. It usually resolves once the bone has completed growth or activity is lessened.
Sever?s disease is often associated with a growth spurt, when the bones grow but the muscles do not. Therefore the muscles effectively become tighter which results in increased stress at the heel. It may also be related to unusual biomechanics, for instance poor foot posture, muscle tightness or muscle weakness. Overtraining or incorrect training can also play a part. Usually, the cause is a combination of factors.
Pain is usually felt at the back of the heel and around the sides of the heel. If you squeeze the back of the heel from both sides simultaneously and pain is experienced Sever?s disease is more than likely present.
The doctor may order an x-ray because x-rays can confirm how mature the growth center is and if there are other sources of heel pain, such as a stress fracture or bone cyst. However, x-rays are not necessary to diagnose Sever?s disease, and it is not possible to make the diagnosis based on the x-ray alone.
Non Surgical Treatment
Heel pain, unlike the heel spurs, that occur in adults is very uncommon in children. Of those children who do get heel pain, by far the most common cause is a disturbance to the growing area at the back of the heel bone (calcaneus) where the strong achilles tendon attaches to it. This is known as Sever’s disease or calcaneal apophysitis (inflammation of the growth plate). It is most common between the ages of 10 to 14 years of age. These are one of several different ‘osteochondroses’ that can occur in other parts of the body, such as at the knee (Osgood-Schlatters Disease).
