Sever?s disease is a condition occurring in pre-adolescents that causes pain, swelling and soreness in the heel bone, also known as the calcaneus. Sever?s disease causes pain on either side of and/or
on the bottom of the heel. During a period of pre-adolescent development, the growing heel bone can be overused when the child is involved in a lot of running and jumping activities. Impact on the
heel bone and repeated traction on the growing bone from the Achilles tendon can lead to swelling in the area.
Severs disease is often associated with a rapid growth spurt. As the bones get longer, the muscles and tendons become tighter as they cannot keep up with the bone growth. The point at which the
achilles tendon attaches to the heel becomes inflamed and the bone starts to crumble (a lot like osgood schlatters disease of the knee). Tight calf muscles may contribute as the range of motion at
the ankle is reduced resulting in more strain on the achilles tendon. Sever's disease is the second most common injury of this type which is known as an apophysitis.
Most children with Sever's complain of pain in the heel that occurs during or after activity (typically running or jumping) and is usually relieved by rest. The pain may be worse when wearing cleats.
Sixty percent of children's with Sever's report experiencing pain in both heels.
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 have Sever's disease, the following is suggested, cut back on sporting activities, don't stop, just reduce the amount until symptoms improve (if the condition has been present for a
while, a total break from sport may be needed later) avoid going barefoot, 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). Stretch the calf muscles, provided the stretch does not cause pain in the area of the growth plate). 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.
With proper care, your child should feel better within 2 weeks to 2 months. Your child can start playing sports again only when the heel pain is gone. Your doctor will let you know when physical
activity is safe.
