Sever?s disease is the most common cause of heel pain in the growing athlete and is due to overuse and repetitive microtrauma of growth plates in the heel. It occurs in children ages 7 to 15, with the majority of patients presenting between 10 and 14 years of age. Sever?s disease will go away on its own when it is used less or when the bone is through growing, but it can recur (for example, at the start of a new sports season). Traditionally, the only known cure was for children to outgrow the condition, with recurrences happening an average of 18 months before this occurs.
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).
Athletes with Sever?s disease are typically aged 9 to 13 years and participate in running or jumping sports such as soccer, football, basketball, baseball, and gymnastics. The typical complaint is heel pain that develops slowly and occurs with activity. The pain is usually described like a bruise. There is rarely swelling or visible bruising. The pain is usually worse with running in cleats or shoes that have limited heel lift, cushion, and arch support. The pain usually goes away with rest and rarely occurs with low-impact sports such as bicycling, skating, or swimming.
Physical examination varies depending on the severity and length of involvement. Bilateral involvement is present in approximately 60% of cases. Most patients experience pain with deep palpation at the Achilles insertion and pain when performing active toe raises. Forced dorsiflexion of the ankle also proves uncomfortable and is relieved with passive equinus positioning. Swelling may be present but usually is mild. In long-standing cases, the child may have calcaneal enlargement.
Non Surgical Treatment
The primary method of treating Sever?s disease is taking time off from sports and other physical activities to alleviate the pressure on the heel bone. During the healing period, your child?s doctor may also recommend physical therapy or any type of exercise that involves stretching and strengthen leg muscles and tendons. Wrapping ice in a towel and placing it under the child?s heel will also help to alleviate and reduce pain and swelling.
Perform a well rounded dynamic warm up before activity. Perform a good static stretching routine after activity. Increase core strength. Perform exercises that emphasize active lengthening of the calf muscles. Use proper footwear. Avoid excessive running or jumping on hard surfaces like concrete by using better surfaces such as asphalt, gymnasium floors or grass.
