Sever?s disease is repetitive micro trauma or overuse of the heel in young athletes. Sever?s is caused by overloading the insertion of the Achilles tendon onto the calcaneus and the apophyseal growth plate. Active Children (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.
Sever's disease usually develops as a result of overuse and is common in active children between the ages of 8 to 12. Activities that involve running or jumping can cause undue stress on the calcaneal apophysis. This in turn leads to the development of microscopic damage to the calcaneal apophysis resulting in inflammation and pain. Poor flexibility of the calf muscles and of the Achilles tendon, overpronation (feet rolled in) and inappropriate footwear are some of the other factors that can cause Sever's disease.
If your child is suffering from this disease they will be experiencing pain and tenderness in the back of their foot. This soreness can also extend to the sides of the feet. Other sure signs of this disorder include swelling and sensitivity to touch. Because of the amount of discomfort, your child may find it difficult to walk or run. Pay attention to the way your child is walking. If you notice unusual posture or abnormal gait they may be avoiding placing pressure on the heel. These symptoms typically become apparent during activity and exercise or directly following it. If your child is indicating pain in their heel, schedule an appointment with us today.
The x-ray appearance usually shows the apophysis to be divided into multiple parts. Sometimes a series of small fragments is noted. Asymptomatic heels may also show x-ray findings of resporption, fragmentation and increased density. But they occur much less often in the normal foot. Pulling or ?traction? of the Achilles tendon on the unossified growth plate is a likely contributing factor to Sever?s disease. Excessive pronation and a tight Achilles and limited dorsiflexion may also contribute to the development of this condition.
Non Surgical Treatment
A physiotherapist will assess your pain, presentation and biomechanics. They can then treat your sever?s disease with hands on techniques which may include massage, manual therapy and taping. Your physiotherapist can then provide advice on what you can do at home to further progress your treatment, this may include stretching, strengthening and activity modification. In some cases orthotic prescription may be of benefit.
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.
