Although the name might sound pretty frightening, Sever’s disease is really a common heel injury that occurs in kids. It can be painful, but is only temporary and has no long-term effects. Calcaneal apophysitis is a painful inflammation of the heel?s growth plate. It typically affects children between the ages of 8 and 14 years old, because the heel bone (calcaneus) is not fully developed until at least age 14. Until then, new bone is forming at the growth plate (physis), a weak area located at the back of the heel. When there is too much repetitive stress on the growth plate, inflammation can develop. Calcaneal apophysitis is also called Sever?s disease, although it is not a true ?disease.? It is the most common cause of heel pain in children, and can occur in one or both feet. Heel pain in children differs from the most common type of heel pain experienced by adults. While heel pain in adults usually subsides after a period of walking, pediatric heel pain generally doesn?t improve in this manner. In fact, walking typically makes the pain worse.
The usual cause is directly related to overuse of the bone and tendons in the heel. This can come from playing sports or anything that involves a lot of heel movement. It can be associated with starting a new sport, or the start of a new season, or too much weight bearing on the heel. Also, excessive traction could cause this, since the bones and tendons are still developing. Many children who over pronate their feet exhibit symptoms and in most patients, it usually involves both heels.
The patient complains of activity related pain that usually settles with rest. On Examination the heel bone – or calcaneum – is tender on one or both sides. The gastrocnemius and soleus muscles (calf muscles) may be tight and bending of the ankle might be limited because of that. Foot pronation (rolling in) often exacerbates the problem. There is rarely anything to see and with no redness or swelling and a pain that comes and goes mum and dad often wait before seeking advice on this condition. The pain may come on partway through a game and get worse or come at the end of the game. Initially pain will be related only to activity but as it gets worse the soreness will still be there the next morning and the child might limp on first getting up.
A Podiatrist can easily evaluate your child?s feet, to identify if a problem exists. Through testing the muscular flexibility. If there is a problem, a treatment plan can be create to address the issue. At the initial treatment to control movement or to support the area we may use temporary padding and strapping and depending on how successful the treatment is, a long-term treatment plan will be arranged. This long-term treatment plan may or may not involve heel raises, foot supports, muscle strengthening and or stretching.
Non Surgical Treatment
Primary treatment involves the use of heel cups or orthotics with a sturdy, supportive plastic shell. Treatment may also include cutting back on sports activities if pain interferes with performance, calf muscle stretching exercises, icing, and occasionally anti-inflammatory medications. Severe cases may require the short term use of a walking boot or cast.
