Sever?s disease is also known as calcaneal apophysitis, which is a medical condition that causes heel pain In one or both feet. The disease is known to affect children between the ages of 8 and 14. Sever?s disease occurs when part of the child?s heel known as the growth plate (calcaneal epiphysis) is attached to the Achilles tendon. This area can suffer injury when the muscles and tendons of the growing foot do not keep pace with bone growth. Therefore, the constant pain which one experiences at the back of the heel will make the child unable to put any weight on the heel. The child is then forced to walk on their toes. Toe gait- develops in which the child must change the way they walk to avoid placing weight on the heel. This can lead to other problems as well in the future.
Sever disease, like other similar conditions (eg, Osgood-Schlatter disease, little-leaguer’s elbow, and iliac apophysitis), is believed to be caused by decreased resistance to shear stress at the bone-growth plate interface. Studies have indicated that traction apophyses have a higher composition of fibrocartilage than epiphyses subjected more to axial load, which are composed predominantly of hyaline cartilage. The anatomy of the calcaneal apophysis lends to significant shear stress because of its vertical orientation and the direction of pull from the strong gastrocnemius-soleus muscle group.
The pain associated with Sever’s disease is usually felt along the back of the heel and becomes worse when running or walking. In some children, the pain is so severe they may limp when walking. One of the diagnostic tests for Sever’s disease is the “squeeze test”. Squeezing both sides of the heel together will produce immediate discomfort. Many children feel pain immediately upon waking and may have calf muscle stiffness in the morning.
A physical exam of the heel will show tenderness over the back of the heel but not in the Achilles tendon or plantar fascia. There may be tightness in the calf muscle, which contributes to tension on the heel. The tendons in the heel get stretched more in patients with flat feet. There is greater impact force on the heels of athletes with a high-arched, rigid foot.
Non Surgical Treatment
If your child lets you know that his heels are hurting, schedule a doctor’s appointment. Your family doctor may or may not refer you to a podiatrist. Treatment for Sever’s Disease typically consists of one or more of the following steps. Reducing physical activity. Because Sever’s Disease appears to be most common in athletic children, reducing exercise periods will relieve pressure on the heel bones, thereby reducing pain. Your doctor may recommend that your child take a complete break from athletic activity for a set amount of time. Icing the heel bones can help to lower both inflammation and pain levels. Use a cold pack or wrap ice in a towel and apply it to the heels. A new exercise regimen that involves simple stretches designed to lengthen the calf muscles and tendons. Your doctor may prescribe the use of orthotic shoe inserts that will assist your child in maintaining a good level of physical activity. HTP Heel Seats may be an excellent option and have been purchased by many parents as an effective aide for children suffering from Sever’s Disease. Read about HTP Heel Seats here and ask your doctor if they are right for your child’s unique case. In extreme cases, a doctor may recommend a plaster cast or boot, but typically only if other less cumbersome solutions fail to reduce pain. Some doctors may prescribe anti-inflammatory medications. Never give these to a child yourself, without first seeking a doctor’s advice. Some medications carry the risk of serious side effects for children. Only give medications if specifically prescribed your child’s physician.
Stretching exercises can help. It is important that your child performs exercises to stretch the hamstring and calf muscles, and the tendons on the back of the leg. The child should do these stretches 2 or 3 times a day. Each stretch should be held for about 20 seconds. Both legs should be stretched, even if the pain is only in 1 heel. Your child also needs to do exercises to strengthen the muscles on the front of the shin. To do this, your child should sit on the floor, keeping his or her hurt leg straight. One end of a bungee cord or piece of rubber tubing is hooked around a table leg. The other end is hitched around the child’s toes. The child then scoots back just far enough to stretch the cord. Next, the child slowly bends the foot toward his or her body. When the child cannot bend the foot any closer, he or she slowly points the foot in the opposite direction (toward the table). This exercise (15 repetitions of “foot curling”) should be done about 3 times. The child should do this exercise routine a few times daily.
