Overview
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).
Causes
Sever condition is caused by sprain injury where the Achilles tendon attaches to the calcaneus bone at the back of the heel. Sever condition occurs in adolescent or older children, particularly active boys. It can be very painful. It is one of those conditions commonly referred to as "growing pains." Patients are evaluated for signs of conditions that can mimic Sever condition, such as ankylosing spondylitis and other forms of arthritis. Usually Sever condition is self-limited; that is, it disappears as the child ages.
Symptoms
The symptoms include pain, tenderness, swelling or redness in the heel, and they might have difficulty walking or putting pressure on the heel. If you notice that your child suddenly starts walking around on their toes because their heels hurt, that?s a dead giveaway. Kids who play sports might also complain of foot pain after a game or practice. As they grow, the muscles and tendons will catch up and eventually the pressure will subside along with the pain. But in the meantime, it can become very uncomfortable.
Diagnosis
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
The treatment of Sever's disease depends upon the severity of symptoms experienced by the patient. Care is initiated with a simple program of stretching and heel elevation to weaken the force applied to the calcaneus by the Achilles tendon. If stretches and heel elevation are unsuccessful in controlling the symptoms of Sever's disease, children should be removed from sports and placed on restricted activities. Mild Symptoms. Wear a 3/8 heel lift at all times (not just during physical activity). It is important to use a firm lift and not a soft heel pad. Calf stretches 6/day for 60 seconds each. Calf stretches are best accomplished by standing with the toes on the edge of a stretching block. Moderate Symptoms. Follow the directions for minor symptoms and decrease activity including elimination of any athletic activity. In addition to stretching by day, a night stretching splint can be worn while sleeping. Severe Symptoms. Follow the directions for mild and moderate symptoms. Children should be removed from sports activities such as football, basketball, soccer or gym class. A below knee walking cast with a heel lift or in severe cases, non-weight bearing fiberglass cast, may be indicated for 4-6 weeks. The cast should be applied in a mildly plantar flexed position. Cam Walkers should not be used for Sever's Disease unless they have a built in heel lift.
Exercise
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.
