Does Calcaneal Apophysitis Always Have To Have Surgery Treatment?


Sever disease refers to a calcaneal apophysitis (an inflammation of the apophysis of the heel) which occurs in children and young adolescents. It typically presents in active young children (especially ones who engage in jumping and running sports).


During the growth spurt of early puberty, the heel bone (also called the calcaneus) sometimes grows faster than the leg muscles and tendons. This can cause the muscles and tendons to become very tight and overstretched, making the heel less flexible and putting pressure on the growth plate. The Achilles tendon (also called the heel cord) is the strongest tendon that attaches to the growth plate in the heel. Over time, repeated stress (force or pressure) on the already tight Achilles tendon damages the growth plate, causing the swelling, tenderness, and pain of Sever's disease. Such stress commonly results from physical activities and sports that involve running and jumping, especially those that take place on hard surfaces, such as track, basketball, soccer, and gymnastics.


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.


A doctor or other health professional such as a physiotherapist can diagnose Sever?s disease by asking the young person to describe their symptoms and by conducting a physical examination. In some instances, an x-ray may be necessary to rule out other causes of heel pain, such as heel fractures. Sever?s disease does not show on an x-ray because the damage is in the cartilage.

Non Surgical Treatment

Traditional treatment involved simply telling children that they can?t play sport for a year. This is not popular for children or parents and abstaining from sport leads to other problems when wanting to return. Treatments focus on improving foot and lower limb function with footwear selection, heel raises, calf stretching, prescription orthoses, run technique training and training modifications. This results in a reduced load through the growth plate and the child can perform more activity before the growth plate becomes inflamed. Rest will always reduce the Sever?s disease symptoms, however this is always the last option.


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.
