Although the name might sound pretty frightening, Sever’s disease is really a common heel injury that occurs in kids. It can be painful, but is only temporary and has no long-term effects. Calcaneal apophysitis is a painful inflammation of the heel?s growth plate. It typically affects children between the ages of 8 and 14 years old, because the heel bone (calcaneus) is not fully developed until at least age 14. Until then, new bone is forming at the growth plate (physis), a weak area located at the back of the heel. When there is too much repetitive stress on the growth plate, inflammation can develop. Calcaneal apophysitis is also called Sever?s disease, although it is not a true ?disease.? It is the most common cause of heel pain in children, and can occur in one or both feet. Heel pain in children differs from the most common type of heel pain experienced by adults. While heel pain in adults usually subsides after a period of walking, pediatric heel pain generally doesn?t improve in this manner. In fact, walking typically makes the pain worse.
Having flatfeet or very pronated feet can make one prone to Sever’s disease. But also patient?s that have a very high arch foot structure tend to have a very high shock and high impact heel strike. This also puts extra stress on the heel and apophysis.
The symptoms of Sever?s disease occur in the heel and the foot, and may worsen with activity. Pain and stiffness can occur in one or both heels. Symptoms can include. Swelling in the heel. Redness in the heel. Antalgic gait (such as limping). Foot pain or stiffness first thing in the morning or while walking. Pain that is worsened by squeezing the heel.
This can include physical examination and x-ray evaluation. X-rays may show some increased density or sclerosis of the apophysis (island of bone on the back of the heel). This problem may be on one side or bilateral.
Non Surgical Treatment
The initial treatment is rest, relieve the pain and treat the underlying cause. The foot and ankle should be rested so that the apophysis it is not being continually ?injured?. A small heel (sorbothane heel insert) raise can used to raise the heel and take the stretch off the Achilles tendon. It may be sufficient to stop your child playing sport but some children require a short period of bed or couch rest. Some children find resting very difficult and require the use of braces or plasters or boots to slow them down. Using crutches is advised. Severs is usually caused by tight muscles. A stretching program should be followed usually supervised by a physiotherapist. The stretching program may need to be undertaken up to 5 times a day. If flat feet are a problems orthotics (insoles) should be used. The pain should be controlled by rest (limiting activity) and ice (icing the painful area 3-4 times a day – making sure the skin is not burnt), Simple pain killers can be used such as paracetamol as well as anti-inflammatory tablets and cream. Severs disease usually goes away with time. When your child stops growing, the pain and swelling should go away because the growing (weak) area fuses and becomes solid bone which is very strong.
It may take several weeks or months for the pain to completely stop. When the pain is completely gone, your child may slowly return to his or her previous level of activity.
