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.
Sever?s disease is an osteochondrosis caused by overloading the insertion of the Achilles tendon onto the calcaneus and the apophyseal growth plate in this area. This C-shaped growth zone can become inflamed secondary to repetitive traction stress of the Achilles tendon. Calcaneal apophysitis is a common injury in young athletes and is believed to be caused by running and jumping. Active Children and adolescents (usual age of occurrence 7 to 15 years), particularly during the pubertal growth spurt or at the beginning of a sport season (e.g. gymnasts, basketball and football players), often suffer from this condition. This disease occurs most commonly during the early part of the growth spurt. A boy-to-girl ratio is 2-3:1. None of these causative factors has been tested prospectively and, where tested, none of the measurements has been carried out systematically, and reliability or validity of the measurements has not been considered.
Symptoms include heel pain related to sports activities and worsen after those sport and exercise activities. However, some children who are not in a sport may also get this if they are physically active. If you notice that your child is ?walking on their toes? this is a sign of possible heel pain. The pain is usually on the back of the heel, the sides of the heel, the bottom of the heel, or a combination of all of these. We typically don't see swelling with this, however if pressure is applied to the sides of the heel pain may be reported. Sometimes the pain is so bad the child will have to limp, or take a break from sports activity either for a few days or few months.
Children or adolescents who are experiencing pain and discomfort in their feet should be evaluated by a physician. In some cases, no imaging tests are needed to diagnose Sever?s disease. A podiatrist or other healthcare professional may choose to order an x-ray or imaging study, however, to ensure that there is no other cause for the pain, such as a fracture. Sever?s disease will not show any findings on an x-ray because it affects cartilage.
Non Surgical Treatment
Orthotics or special shoe inserts can also be used to cushion the heel and reduce pain. Physical Therapy. If avoiding physical activities fails to clear up Sever?s disease Genesis Orthopedics & Sports Medicine may proceed with physical therapy. Physical therapy strengthens the muscles and tendons in the heel, releasing pressure and eventually reducing pain.
The surgeon may select one or more of the following options to treat calcaneal apophysitis. Reduce activity. The child needs to reduce or stop any activity that causes pain. Support the heel. Temporary shoe inserts or custom orthotic devices may provide support for the heel. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation. Physical therapy. Stretching or physical therapy modalities are sometimes used to promote healing of the inflamed issue. Immobilization. In some severe cases of pediatric heel pain, a cast may be used to promote healing while keeping the foot and ankle totally immobile. Often heel pain in children returns after it has been treated because the heel bone is still growing. Recurrence of heel pain may be a sign of calcaneal apophysitis, or it may indicate a different problem. If your child has a repeat bout of heel pain, be sure to make an appointment with your foot and ankle surgeon.
