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.
Children are at a higher risk of developing Sever’s disease when they are in the early stages of a growth spurt. During times of growth, muscles and tendons become extremely tight. Movements during athletic activities like soccer, tennis, and gymnastics can put added force on the growth plate in the heel, which is pulled tight by the Achilles tendon. Over time, the growth plate becomes inflamed and painful. There are several other factors that can increase a child’s risk of developing Sever’s disease, including the following. Excessive pronation. Flat or high arches. Short Achilles tendon. Weight gain (which results in more force on the feet).
A few signs and symptoms point to Sever?s disease, which may affect one or both heels. These include pain at the heel or around the Achilles tendon, Heel pain during physical exercise, especially activities that require running or jumping, worsening of pain after exercise, a tender swelling or bulge on the heel that is sore to touch, calf muscle stiffness first thing in the morning, limping, a tendency to tiptoe.
Sever?s disease is diagnosed based on a doctor?s physical examination of the lower leg, ankle, and foot. If the diagnosis is in question, the doctor may order x-rays or an MRI to determine if there are other injuries that may be causing the heel pain.
Non Surgical Treatment
See a Podiatrist. Minimise inflammation, by the use of ice, rest and reduction of activity. Minimise pain with the use of anti-inflammatory medications. Shoes have been shown to attenuate shock and reduce impact on the heel. Effective cushioning in the rear through specifcally placed cushioning units, such as GEL under the heel. A 10mm heel gradient that creates a more efficient foot posture and therefore reducing strain on the lower limb. Sever’s is self limiting and only possible when the growth plate is still present, and does not exist once the growth plates have closed. Podiatrists have an important role to play in preventing and managing foot problems. Prompt action is important. Problems which are left without assessment or treatment may result in major health risks.
Sever’s disease may be prevented by maintaining good joint and muscle flexibility in the years leading up to, and during, their growth spurts (eg girls 8 to 10, boys 10 to 12). Foot arch problems such as flat feet should be addressed after the age of five if they don’t appear to be self-correcting. If you are concerned, please ask your health practitioner. The most important factor is the amount of weight-bearing exercise your child is currently performing. Finally, LISTEN To Your Child! If your child is suffering heel pain between the ages of 8 to 12, suspect Sever’s disease until proven otherwise. Seek the professional opinion of your foot practitioner regarding its diagnosis and subsequent management.
