Sever?s disease a term used to describe pain in the heel at the base of the Achilles tendon. It usually occurs during or after a growth spurt in adolescence most commonly between the ages of 8-13 in girls and 10-15 for boys. Sever?s disease is more prevalent in children who are physically active. Those with Sever?s disease commonly experience pain during or after sports that involve running and jumping, especially those that take place on hard surfaces.
The cause of Sever’s Disease is not entirely clear but it is most likely due to repeated minor trauma that occurs during high-impact activities that involve running and jumping such as soccer, basketball, and gymnastics. It may also occur when an active child regularly wears shoes with poor heel padding, shock absorbency, or poor arch support. Some additional contributing factors are excessive pronation, an overly tight calf muscle, and other flaws in the biomechanics of a child’s walking stride. Children who are overweight are also at greater risk of developing Sever’s Disease.
The symptoms of Sever?s Disease may vary but usually include generalised pain and discomfort around the back of the heel. Can be one sided or both sides. Starts after child starts a new sport season. May cause child to limp due to pain. Increases with weight bearing activity. Heel becomes red and can be swollen. X-rays are usually inconclusive and simply show the growth plate.
The doctor may order an x-ray because x-rays can confirm how mature the growth center is and if there are other sources of heel pain, such as a stress fracture or bone cyst. However, x-rays are not necessary to diagnose Sever?s disease, and it is not possible to make the diagnosis based on the x-ray alone.
Non Surgical Treatment
The following are different treatment options Rest and modify activity. Limit running and high-impact activity to rest the heel and lessen the pain. Choose one running or jumping sport to play at a time. Substitute low-impact cross-training activities to maintain cardiovascular fitness. This can include biking, swimming, using a stair-climber or elliptical machine, rowing, or inline skating. Reduce inflammation. Ice for at least 20 minutes after activity or when pain increases. Nonsteroidal anti-inflammatory drugs (NSAIDs) may also help. Stretch the calf. Increase calf flexibility by doing calf stretches for 30 to 45 seconds several times per day. Protect the heel. The shoe may need to be modified to provide the proper heel lift or arch support. Select a shoe with good arch support and heel lift if possible. Try heel lifts or heel cups in sports shoes, especially cleats. Try arch support in cleats if flat feet contribute to the problem. Take it one step at a time. Gradually resume running and impact activities as symptoms allow. Sever?s disease usually goes away when the growth plate (apophysis) matures, which should be by age 12 to 13 years in females and 13 to 14 years in males.
