Sever?s Disease is used to describe pain in the back of the heel that comes from an inflamed growth plate in your child?s heel. Sever?s Disease commonly occurs in children from the ages 8-15. The
muscles and tendons become tight as the bones shift and grow. This causes pain when walking or participating in athletic events that require running and jumping.
Heel pain is very common in children due to the fact they are cnstantly growing. In most children, the heel bone (the calcaneus) is not fully developed until the age of 14 or older. Until then, new
bone is forming at the growth plate of the foot (the apophysis, located at the back of the heel), an area which is softer than others due to its role in accommodating the growth. Repetitive stress on
the growth plate due to walking, running and sports causes inflammation in the heel area. Because the heel's growth plate is sensitive, repeated running and pounding on hard surfaces can result in
pediatric heel pain. Children and adolescents who take part in a lot of sport are especially vulnerable. Over-pronation (fallen arches and rolling inwards of the feet) will increase the impact on the
growth plate and is therefore a significant cause and a major contributing factor to heel pain in children.
If your child is suffering from this disease they will be experiencing pain and tenderness in the back of their foot. This soreness can also extend to the sides of the feet. Other sure signs of this
disorder include swelling and sensitivity to touch. Because of the amount of discomfort, your child may find it difficult to walk or run. Pay attention to the way your child is walking. If you notice
unusual posture or abnormal gait they may be avoiding placing pressure on the heel. These symptoms typically become apparent during activity and exercise or directly following it. If your child is
indicating pain in their heel, schedule an appointment with us today.
Sever?s disease can be diagnosed based on the symptoms your child has. Your child?s doctor will conduct a physical examination by squeezing different parts of your child?s foot to see if they cause
any pain. An X-ray may be used to rule out other problems, such as a broken bone or fracture.
Non Surgical Treatment
Treatment revolves around decreasing activity. Usual treatment has been putting children in a boot in slight equinus, or a cast with the foot in slight equinus, thereby decreasing the tension on the
heel cord, which in turn pulls on the growth plate at the heel. As the pain resolves, children are allowed to go back to full activities. Complete resolution may be delayed until growth of the foot
is complete (when the growth plate fuses to the rest of the bone of the heel). A soft cushioning heel raise is really important (this reduces the pull from the calf muscles on the growth plate and
increases the shock absorption, so the growth plate is not knocked around as much). The use of an ice pack after activity for 20mins is often useful for calcaneal apophysitis, this should be repeated
2 to 3 times a day. As a pronated foot is common in children with this problem, a discussion regarding the use of long term foot orthotics may be important. If the symptoms are bad enough and are not
responding to these measures, medication to help with inflammation may be needed. In some cases the lower limb may need to be put in a cast for 2-6 weeks to give it a good chance to heal.
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.
