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.
Overuse and stress on the heel bone through participation in sports is a major cause of calcaneal apophysitis. The heel?s growth plate is sensitive to repeated running and pounding on hard surfaces, resulting in muscle strain and inflamed tissue. For this reason, children and adolescents involved in soccer, track, or basketball are especially vulnerable. Other potential causes of calcaneal apophysitis include obesity, a tight Achilles tendon, and biomechanical problems such as flatfoot or a high-arched foot.
The most common symptoms of Sever?s involves pain or tenderness in one or both heels. This pain usually occurs at the back of the heel, but can also extend to the sides and bottom of the heel. A child with Sever?s may also have these common problems, Heel pain with limping, especially after running. Difficulty walking, Discomfort or stiffness in the feet upon awaking. Swelling and redness in the heel, Symptoms are usually worse during or after activity and get better with rest.
A doctor can usually tell that a child has Sever’s disease based on the symptoms reported. To confirm the diagnosis, the doctor will probably examine the heels and ask about the child’s activity level and participation in sports. The doctor might also use the squeeze test, squeezing the back part of the heel from both sides at the same time to see if doing so causes pain. The doctor might also ask the child to stand on tiptoes to see if that position causes pain. Although imaging tests such as X-rays generally are not that helpful in diagnosing Sever’s disease, some doctors order them to rule out other problems, such as fractures. Sever’s disease cannot be seen on an X-ray.
Non Surgical Treatment
Treatment is initially focused on reducing the present pain and limitations and then on preventing recurrence. Limitation of activity (especially running and jumping) usually is necessary. In Micheli and Ireland’s study, 84% of 85 patients were able to resume sports activities after 2 months. If the symptoms are not severe enough to warrant limiting sports activities or if the patient and parents are unwilling to miss a critical portion of the sport season, wearing a half-inch inner-shoe heel lift (at all times during ambulation), a monitored stretching program, presport and postsport icing, and judicious use of anti-inflammatory agents normally reduce the symptoms and allow continued participation. If symptoms worsen, activity modification must be included. For severe cases, short-term (2-3 weeks) cast treatment in mild equinus can be used.
Recovery time will vary from patient to patient. Age, health, previous injuries, and severity of symptoms will affect recovery time. Your compliance with the stretching program and the other recommendations made by your doctor will also determine your healing time. Heel pain often completely resolves after a child?s heel bone has stopped its period of growth.
