Sever?s disease, also known as calcaneal apophysitis or Osgood-Schlatter syndrome of the foot. This traction apophysitis is secondary to repetitive microtraumata or overuse of the heel in young athletes. The calcaneus is situated at the most plantar posterior aspect of the foot. The Achilles tendon inserts to the lower, posterior and slightly medial aspect of the calcaneus. The plantar fascia originates from the medial tubercle on the plantar aspect of the calcaneus. Proximal to the epiphysis is the apophysis, where the Achilles tendon actually inserts. The calcaneal growth plate and apophysis are situated in an area subject to high stress from the plantar and Achilles tendon.
Sever's disease is a common cause of heel pain in physically active growing kids. It usually occurs during the growth spurt of adolescence, the approximately 2-year period in early puberty when kids grow most rapidly. This growth spurt can begin anytime between the ages of 8 to 13 for girls and 10 to 15 for boys. Peak incidences are girls, 8 to 10 years old. boys, 10 to 12 years old.
Sever?s disease is a clinical diagnosis based on the youth?s presenting symptoms, rather than on diagnostic tests. While x-rays may be ordered in the process of diagnosing the disease, they are used primarily to rule out bone fractures or other bone abnormalities, rather than to confirm the disease. Common Characteristics of Sever?s Disease include Posterior inferior heel pain. Pain is usually absent when waking in the morning. Increased pain with weight bearing, running, or jumping (or activity-related pain). Area often feels stiff or inflexible. Youth may limp at the end of physical activity. Tenderness at the insertion of the tendons. Limited ankle dorsiflexion range that is secondary to tightness of the Achilles tendon. Activity or sport practices on hard surfaces can also contribute to pain, as well as poor quality shoes, worn out shoes, or the wrong shoes for the sport. Typically, the pain from this disease gradually resolves with rest.
Children or adolescents who are experiencing pain and discomfort in their feet should be evaluated by a physician. In some cases, no imaging tests are needed to diagnose Sever?s disease. A podiatrist or other healthcare professional may choose to order an x-ray or imaging study, however, to ensure that there is no other cause for the pain, such as a fracture. Sever?s disease will not show any findings on an x-ray because it affects cartilage.
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.
Perform a well rounded dynamic warm up before activity. Perform a good static stretching routine after activity. Increase core strength. Perform exercises that emphasize active lengthening of the calf muscles. Use proper footwear. Avoid excessive running or jumping on hard surfaces like concrete by using better surfaces such as asphalt, gymnasium floors or grass.
