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.
Heel pain can also be caused by a stress fracture in the heel, bursitis, tendonitis, bone cysts, and rheumatologic disorders. If the athlete is not active in impact sports or is not between age 9 and 13 years, other conditions should be considered.
Some of the most common signs and symptoms associated with Sever?s disease include. Heel pain or tenderness in one or both heels, usually at the back of the heel. Pain or discomfort upon waking, or when the heel is squeezed. Heel pain that is worse during or following activity. Limping. Heel swelling or redness. Tight calf muscles. Decreased ankle range of motion.
A doctor can usually tell that a child has Sever’s disease based on the symptoms reported. To confirm the diagnosis, the doctor will probably examine the heels and ask about the child’s activity level and participation in sports. The doctor might also use the squeeze test, squeezing the back part of the heel from both sides at the same time to see if doing so causes pain. The doctor might also ask the child to stand on tiptoes to see if that position causes pain. Although imaging tests such as X-rays generally are not that helpful in diagnosing Sever’s disease, some doctors order them to rule out other problems, such as fractures. Sever’s disease cannot be seen on an X-ray.
Non Surgical Treatment
The treatment of Sever’s disease depends upon the severity of symptoms experienced by the patient. Care is initiated with a simple program of stretching and heel elevation to weaken the force applied to the calcaneus by the Achilles tendon. If stretches and heel elevation are unsuccessful in controlling the symptoms of Sever’s disease, children should be removed from sports and placed on restricted activities. Mild Symptoms. Wear a 3/8 heel lift at all times (not just during physical activity). It is important to use a firm lift and not a soft heel pad. Calf stretches 6/day for 60 seconds each. Calf stretches are best accomplished by standing with the toes on the edge of a stretching block. Moderate Symptoms. Follow the directions for minor symptoms and decrease activity including elimination of any athletic activity. In addition to stretching by day, a night stretching splint can be worn while sleeping. Severe Symptoms. Follow the directions for mild and moderate symptoms. Children should be removed from sports activities such as football, basketball, soccer or gym class. A below knee walking cast with a heel lift or in severe cases, non-weight bearing fiberglass cast, may be indicated for 4-6 weeks. The cast should be applied in a mildly plantar flexed position. Cam Walkers should not be used for Sever’s Disease unless they have a built in heel lift.
In some cases, children will simply outgrow Sever’s Disease when they reach a certain age, but this does not mean that symptoms should be ignored. If children express that they are in pain, this should always be taken seriously by their parents or guardians. Heel pain may be a sign of Sever’s Disease and this condition should not be left untreated, due to the damage it can cause to the growing heel bones. Scheduling a doctor’s appointment is always the first step to take in gaining a diagnosis of symptoms and speedy help for the child.
