Sever?s Disease is often misdiagnosed as a simple growing pains and affects boys far more often than girls, especially between the ages of 8 and 14. It is extremely common in children that play Soccer, Basketball, And Hockey. However it is not limited to these sports alone, nor is it simply a pre-season type condition related to fitness. Sever?s Disease sounds terrible, but there is no need to panic as it is not a contagious or incurable condition. In children, there is a growth plate in the heel bone, which at puberty becomes solid and forms part of the heel, however prior to puberty it can cause pain if the child?s foot rolls inwards or outwards too much, causing increased stress on this growth plate and inturn causes pain.
There are many biomechanical factors that predispose a young athlete to calcaneal apophysitis. The majority of patients will present with an ankle equinus deformity, which ultimately exerts an increased pulling force to the Achilles insertion and non-ossified apophysis. Furthermore, patients may present with hyperpronation of the rearfoot. This allows more of a ?teeter-totter? effect or lack of motion control on the frontal plane of the calcaneus.
The condition can be quite disabling and tends to affect those who are very busy with sporting activities. In the initial stages of the condition, most children displaying signs of Severs disease will tend to hobble or limp off the sports field or court and complain of sore heels near the end of activity. As the condition progresses, children may complain of pain during activity and in severe cases prior to sporting activities. Kids heel pain can be quite discouraging for active children but, early treatment can resolve this type of foot pain in children very quickly.
Low-grade inflammation of the calcaneal apophysis cannot be seen on x-ray. Therefore, although x-rays are often done to rule out bony injuries in children with Sever's disease these x-rays are usually normal. Advanced Sever's disease can be seen on x-ray but usually the problem is treated before it reaches this point. Other diagnostic tests, such as bone scans or MRI's, are not usually required in typical cases of Sever's disease. These, or other tests, may be required to rule out other conditions, such as stress fractures of the calcaneus or other bony abnormalities that can mimic Severs disease.
Non Surgical Treatment
The aim of treatment is to reduce the pain and inflammation when gently stretch the muscles. There is likely to be no magic instant cure and the young athlete may have to be patient while they grow. Rest and apply ice or cold therapy to the heel. Do not apply ice directly to the skin but wrap in a wet tea towel to avoid ice burns. Rest from activities which cause pain. If running and playing football makes it worse then reduce or stop this activity and try cycling or swimming to maintain fitness. A temporary measure is to insert a heel pad or heel raise into the shoes. This has the effect of raising the heel and shortening the calf muscles and so taking the strain off the back of the heel. However long term use of a heal raise may shorten the calf muscles when they need stretching. Stretch the calf muscles regularly. Stretching should be done pain free and very gently with this injury. See a sports injury professional who can advise on treatment and rehabilitation.
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.
