Severs disease (calcaneal apophysitis) is a self-limiting condition seen in physically active children. Although there is controversy about the radiographic appearance, some reports propose the importance of fragmentation of the secondary nucleus in the diagnosis of Severs disease. We studied secondary nucleus of the calcaneus with ultrasonography. Twenty-one symptomatic heels of 14 children were examined. All these heels showed fragmentation of the secondary nucleus on both conventional radiograph and sonography. Ultrasonographic examination also showed 2 retrocalcaneal bursitis. Our initial data showed that sonography may be valuable in the diagnosis of Severs disease.
The cause of Sever’s disease is not entirely clear. It is most likely due to overuse or repeated minor trauma that happens in a lot of sporting activities – the cartilage join between the two parts of the bone can not take all the shear stress of the activities. Some children seem to be just more prone to it for an unknown reason – combine this with sport, especially if its on a hard surface and the risk of getting it increases. It can be almost epidemic at the start of some sports seasons, especially winter. At the start of winter, the grounds are often harder, but soften later. Children who are heavier are also at greater risk for developing calcaneal apophysitis.
Pain is usually felt at the back and side of the heel bone. Sometimes there may be pain at the bottom of the heel. The pain is usually relieved when the child is not active and becomes painful with sport. Squeezing the sides of the heel bone is often painful. Running and jumping make the symptoms worse. One or both heels can be affected. In more severe cases, the child may be limping.
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
If your child suffers from Sever?s Disease, it is important you take him or her to see your podiatrist, as it can take some time for the condition to completely resolve. Possible treatment options for Sever?s disease may include. Rest from aggravating activities. Ice massage to reduce localised inflammation. Heel lifts placed inside the shoe to reduce the strain on the growth plate. Athletic footwear advice, poor footwear can sometimes be the major contributing factor in the development of Sever?s disease. Orthotic therapy, if your child has an abnormal foot posture that is contributing to the development of Sever?s disease, this will need to be treated with orthotic therapy. Orthotics for Sever?s disease may need to be prescription (custom-made) or non-prescription foot orthotics depending on your child?s foot posture, Exercise program, stretching exercises to improve flexibility of the leg muscles and strengthening exercises to address any foot muscle weakness or imbalance. Avoid barefoot walking, hill running and training on hard surfaces.
Although Sever’s disease generally heals quickly, it can recur if long-term measures are not taken to protect the heel during a child’s growing years. One of the most important is to make sure that kids wear proper shoes. Good quality, well-fitting shoes with shock-absorbent (padded) soles help to reduce pressure on the heel. The doctor may also recommend shoes with open backs, such as sandals or clogs, that do not rub on the back of the heel. Shoes that are heavy or have high heels should be avoided. Other preventive measures include continued stretching exercises and icing of the affected heel after activity.
