Sever's disease (calcaneal apophysitis) is a common cause of heel pain, particularly in physically active young people who are about to begin puberty. The cause is uncertain, but it is thought that
the long calf bones of the leg grow faster than the surrounding muscle and soft tissue, causing the Achilles tendon to pull uncomfortably tight.
Mechanically, the heel takes a beating. And the apophyseal bone is located near the point of impact for the heel bone at heel strike and with most weight bearing activities. This includes running,
jumping and walking. Heavy impact activities like soccer, football and gymnastics are commonly associated with this problem. In addition to this, there is traction on this apophyseal bone and the
associated physeal line of growth cartilage. This traction on the apopysis (island of bone) along with the impact of weight bearing activities can lead to inflammation and pain. Tight Achilles and
calf muscles also can contribute to this problem, and why stretching is discussed later.
Activity-related pain that occurs on the back of the heel, where the Achilles tendon attaches on to the heel bone. Tenderness, pain & swelling on the heel bone. Difficulty walking or walking with
a limp or on tiptoes.
Most often, a healthcare professional can diagnose Sever?s disease by taking a careful history and administering a few simple tests during the physical exam. A practitioner may squeeze the heel on
either side; when this move produces pain, it may be a sign of Sever?s disease. The practitioner may also ask the child to stand on their tiptoes, because pain that occurs when standing in this
position can also be an indication of Sever?s disease.
Non Surgical Treatment
See a Podiatrist. Minimise inflammation, by the use of ice, rest and reduction of activity. Minimise pain with the use of anti-inflammatory medications. Shoes have been shown to attenuate shock and
reduce impact on the heel. Effective cushioning in the rear through specifcally placed cushioning units, such as GEL under the heel. A 10mm heel gradient that creates a more efficient foot posture
and therefore reducing strain on the lower limb. Sever's is self limiting and only possible when the growth plate is still present, and does not exist once the growth plates have closed. Podiatrists
have an important role to play in preventing and managing foot problems. Prompt action is important. Problems which are left without assessment or treatment may result in major health risks.
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.
