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.
Apart from age, other factors that may contribute to developing Sever?s disease include physical activity, any form of exercise that is weight bearing through the legs or stresses the soft tissue can
exacerbate the pain of the disease. External factors, for example, running on hard surfaces or wearing inappropriate shoes during sport. Overuse injury, very active children may repeatedly but subtly
injure the bones, muscles and tendons of their feet and ankles. In time, the accumulated injuries cause symptoms.
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.
Your Podiatrist or Physiotherapist will assist in diagnosing the injury and the extent of the damage. From this, they will develop a management plan which may include rest or activity modification,
soft tissue treatment such as massage and stretching, correction of biomechanics through heel raises or orthoses and the progression through a series of specific strengthening exercises.
Non Surgical Treatment
Activity Modification: to decrease the pain, limiting sporting activities is essential. Cutting back on the duration, intensity, and frequency can significantly improve symptoms. Heel cord stretching
is important if heel cord tightness is present. Heel cushions/cups or soft orthotics decreases the impact on the calcaneus by distributing and cushioning the weight bearing of the heel. Use of
NSAIDS. Ibuprofen (Nuprin, Motrin) or naproxen (Aleve) can decrease pain and secondary swelling. Ice. Placing cold or ice packs onto the painful heel can alleviate pain. Short-leg cast. For
recalcitrant symptoms a short-leg cast is occasionally used to force rest the heel.
This condition is self limiting - it will go away when the two parts of bony growth join together - this is natural. Unfortunately, Sever's disease can be very painful and limit sport activity of the
child while waiting for it to go away, so treatment is often advised to help relieve it. In a few cases of Sever's disease, the treatment is not successful and these children will be restricted in
their activity levels until the two growth areas join - usually around the age of 16 years. There are no known long term complications associated with Sever's disease.
