Sever's disease, also called calcaneal apophysitis, is a painful bone disorder that results from inflammation (swelling) of the growth plate in the heel. A growth plate, also called an epiphyseal plate, is an area at the end of a developing bone where cartilage cells change over time into bone cells. As this occurs, the growth plates expand and unite, which is how bones grow.
Heel pain is very common in children because of the very nature of their growing feet and legs. In children, the heel bone (the calcaneus) is not fully developed until the age of 14 or older. Until then, new bone is forming at the growth plate of the foot (the apophysis, located at the back of the heel), an area which is softer than others due to its role in accommodating the growth. Repetitive stress on the growth plate due to walking, running and sports causes inflammation in the heel area. Because the heel's growth plate is sensitive, repeated running and pounding on hard surfaces can result in pediatric heel pain. Children and adolescents involved in football, soccer, running or basketball are especially vulnerable. Over-pronation (fallen arches and rolling inwards of the feet) will increase the stress on the growth plate and is therefore a significant cause and a major contributing factor to heel pain in children.
Pain is reproduced through a gentle squeeze of the back of the heel. Children may present with a limp or ?Bouncy gait?. Pain is worse barefoot and often present in the mornings and post exercise. The pain is located at the back of the heel, with localized swelling of the area.
A doctor or other health professional such as a physiotherapist can diagnose Sever?s disease by asking the young person to describe their symptoms and by conducting a physical examination. In some instances, an x-ray may be necessary to rule out other causes of heel pain, such as heel fractures. Sever?s disease does not show on an x-ray because the damage is in the cartilage.
Non Surgical Treatment
Treatment may consist of one or more of the following, Elevating the heel, Stretching hamstring and calf muscles 2-3 times daily, Using R.I.C.E. (Rest, Ice, Compression, Elevation), Foot orthotics, Medication, Physical therapy, Icing daily (morning), Heating therapy, Open back shoe are best and avoid high heel shoe. The Strickland Protocol has shown a positive response in patients with a mean return to sport in less than 3 weeks.
Can Calcaneal Apophysitis Be Prevented? The chances of a child developing heel pain can be reduced by avoiding obesity. Choosing well-constructed, supportive shoes that are appropriate for the child?s activity. Avoiding or limiting wearing of cleated athletic shoes. Avoiding activity beyond a child?s ability.
