During a growth spurt, your child?s heel bone grows faster than the muscles, tendons, and ligaments in her leg. In fact, the heel is one of your child?s first body parts to reach full adult size. When the muscles and tendons can?t grow fast enough to keep up, they are stretched too tight. If your child is very active, especially if she plays a sport that involves a lot of running and jumping on hard surfaces (such as soccer, basketball, or gymnastics), it can put extra strain on her already overstretched tendons. This leads to swelling and pain at the point where the tendons attach to the growing part of her heel.
This condition is more common in boys than girls. It generally presents between the ages of 9-14 and peaks between ages 10-12 years. This injury can reoccur up until the age of 17, when the growth plate of the calcaneous generally closes. These types of injuries will commonly occur during periods of rapid growth. Sever?s Disease occurs more frequently in child with flat feet, but all children with flat feet will not get Sever?s.
The most obvious sign of Sever's disease is pain or tenderness in one or both heels, usually at the back. The pain also might extend to the sides and bottom of the heel, ending near the arch of the foot. A child also may have these related problems, swelling and redness in the heel, difficulty walking, discomfort or stiffness in the feet upon awaking, discomfort when the heel is squeezed on both sides, an unusual walk, such as walking with a limp or on tiptoes to avoid putting pressure on the heel. Symptoms are usually worse during or after activity and get better with rest.
Children or adolescents who are experiencing pain and discomfort in their feet should be evaluated by a physician. In some cases, no imaging tests are needed to diagnose Sever?s disease. A podiatrist or other healthcare professional may choose to order an x-ray or imaging study, however, to ensure that there is no other cause for the pain, such as a fracture. Sever?s disease will not show any findings on an x-ray because it affects cartilage.
Non Surgical Treatment
The immediate goal of treatment is pain relief. Because symptoms generally worsen with activity, the main treatment for Sever's disease is rest, which helps to relieve pressure on the heel bone, decreasing swelling and reducing pain. As directed by the doctor, a child should cut down on or avoid all activities that cause pain until all symptoms are gone, especially running barefoot or on hard surfaces because hard impact on the feet can worsen pain and inflammation. The child might be able to do things that do not put pressure on the heel, such as swimming and biking, but check with a doctor first.
The following exercises are commonly prescribed to patients with Severs disease. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 1 - 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate, advanced and other exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head as far as you can go without pain and provided you feel no more than a mild to moderate stretch in the back of your calf, Achilles tendon or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Calf Stretch with Towel. Begin this exercise with a resistance band around your foot and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 - 20 times provided the exercise is pain free. Once you can perform 20 repetitions consistently without pain, the exercise can be progressed by gradually increasing the resistance of the band provided there is no increase in symptoms. Bridging. Begin this exercise lying on your back in the position demonstrated. Slowly lift your bottom pushing through your feet, until your knees, hips and shoulders are in a straight line. Tighten your bottom muscles (gluteals) as you do this. Hold for 2 seconds then slowly lower your bottom back down. Repeat 10 times provided the exercise is pain free.
