Sever?s disease (also known as calcaneal apophysitis) is a type of bone injury in which the growth plate in the lower back of the heel, where the Achilles tendon (the heel cord that attaches to the growth plate) attaches, becomes inflamed and causes pain. Sever?s disease is the most common cause of heel pain in children, especially those who exercise or play sports on a regular basis.
Sever?s disease is often associated with a growth spurt, when the bones grow but the muscles do not. Therefore the muscles effectively become tighter which results in increased stress at the heel. It may also be related to unusual biomechanics, for instance poor foot posture, muscle tightness or muscle weakness. Overtraining or incorrect training can also play a part. Usually, the cause is a combination of factors.
In Sever?s disease, heel pain can be in one or both heels. It usually starts after a child begins a new sports season or a new sport. Your child may walk with a limp. The pain may increase when he or she stands on tiptoe. Your child?s heel may hurt if you squeeze both sides toward the very back. This is called the squeeze test. Your provider may also find that your child?s heel tendons have become tight.
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
Treatment depends on the severity of the condition, but may include relative rest and modified activity, a physiotherapist can help work out what, and how much, activity to undertake. Cold packs, apply ice or cold packs to the back of the heels for around 15 minutes after any physical activity, including walking. Shoe inserts, small heel inserts worn inside the shoes can take some of the traction pressure off the Achilles tendons. This will only be required in the short term. Medication, pain-relieving medication may help in extreme cases, but should always be combined with other treatment and following consultation with your doctor). Anti-inflammatory creams are also an effective management tool. Splinting or casting, in severe cases, it may be necessary to immobilise the lower leg using a splint or cast, but this is rare. Time, generally the pain will ease in one to two weeks, although there may be flare-ups from time to time. Correction of any biomechanical issues, a physiotherapist can identify and discuss any biomechanical issues that may cause or worsen the condition. Education on how to self-manage the symptoms and flare-ups of Sever?s disease is an essential part of the treatment.
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.
