Sever's disease, is a musculoskeletal condition occurring in adolescence that symptomatically manifests as posterior heel pain during ambulation. Often participation in physical activity is severely limited resulting in frustration for children and parents alike. Conservative treatment options have included rest, abstinence from athletic activity, heel lifts, foot orthotic devices, ice, and calf-stretching exercise. The authors are proposing arch taping as an additional viable treatment option for controlling heel pain during athletic and other weight-bearing activities in patients with Sever's disease.
Children are at greatest risk of developing Sever's disease when they have reached the early part of a growth spurt in early puberty. For girls, this is typically around ages 8 to 10. For boys, it happens somewhere between the ages of 10 to 12. By the age of 15, the back of the heel has typically stopped growing in most children, and Sever's disease becomes rare. Any running or jumping activities can increase the odds that a child will develop Sever's disease. Soccer and gymnastics are two common sports that tend to put kids at risk.
Sharp pain will be present in the affected heel (or both heels), especially while running or walking. Pain can be heightened following activity. The area will be tender to the touch and usually becomes inflamed or reddened. It may also be painful to press on the heel with a finger from the back or to squeeze the sides together; the latter is particularly common. You might notice stiffness in some of the surrounding muscles, making regular movements more difficult to achieve. This and the pain can manifest physically in abnormal practices like tiptoeing or limping. In some cases a lump can be detected on the back of the heel, though it may be so small as to defy detection.
Sever condition is diagnosed by detecting the characteristic symptoms and signs above in the older children, particularly boys between 8 and 15 years of age. Sometimes X-ray testing can be helpful as it can occasionally demonstrate irregularity of the calcaneus bone at the point where the Achilles tendon attaches.
Non Surgical Treatment
Reduce activity, avoid going barefoot, and cushion the child's heel with shock absorbency. It is very important that your child wear shoes with padded heel surfaces and shoes with good arch supports even when not participating in sports. A heel cup or soft pediatric shoe insert is very important to reduce the pull from the calf muscles on the growth plate and to increase shock absorption and reduce irritation. The use of an ice pack after activity for 20 minutes is often useful. Your health care provider may also prescribe anti-inflammatory drugs or custom orthotics.
For children with Sever's disease, it is important to habitually perform exercises to stretch the hamstrings, calf muscles, and the tendons on the back of the leg. Stretching should be performed 2-3 times a day. Each stretch should be performed for 20 seconds, and both legs should be stretched, even if the pain is only in one heel. Heel cups or an inner shoe heel lifts are often recommended for patient suffering from Sever's disease. Wearing running shoes with built in heel cups can also decrease the symptoms because they can help soften the impact on the heel when walking, running, or standing.
