INTRODUCTION

Sever's disease or Calcaneal apophysitis is a condition that affects children between the ages of 10 and 13 years. It is characterized by pain in one or both heels with walking. During this phase of life, growth of the bone is taking place at a faster rate than the tendons. Hence there is a relative shortening of the heel-cord compared to the leg bones. As a result, the tension the heel-cord applies to the heel bone at its insertion is very great. Moreover, the heel cord is attached to a portion of the calcaneus (heel bone) that is still immature, consisting of a mixture of bone and growing cartilage, called the calcaneal apophysis, which is prone to injury. Compounding to this is the fact that all these changes are happening in a very active child, prone to overuse. The end result is therefore an overuse syndrome of injury and inflammation at the heel where the heel cord (Achilles Tendonitis) inserts into the heel bone (Calcaneal apophysitis).

The typical patient is a child between 10 and 13 years of age, complaining of pain in one or both heels with running and walking. The pain is localized to the point of the heel where the tendo-Achilles inserts into the calcaneus, and is tender to deep pressure at that site. Walking on his toes relieves the pain.

The actual pathology of the condition is one of more of an overuse syndrome in which the growth plate of the heel may become slightly displaced, causing pain. Biopsies of similar conditions have shown changes consistent with separation of the cartilage. The condition is very similar to Osgood-Schlatter’s disease which occurs at the knee.

• Help an overweight child lose weight.
• Encourage moderate exercise, avoiding extremes.

• Ignore the pain. You can not grow out of this disease!

WHAT THE CHIROPODIST/ FAMILY DOCTOR WILL DO

Treatment revolves around decreasing activity. Our usual treatment has been putting children in a boot in slight equinus, or a cast with the foot in slight equinus, thereby decreasing the tension on the heel cord, which in turn pulls on the growth plate at the heel. As the pain resolves, children are allowed to go back to full activities.

• Complete resolution my be delayed until growth of the foot is complete -- when the growth plate fuses to the rest of the bone of the heel.
