Overview
Sever's disease is a common cause of heel pain in adolescence. Developing, physically active ?kids? are more prone to Sever's. During puberty the calcaneus consist of two developing sites of bone known as ossification centres. These two areas are seperated by an area of cartilage known as the calcaneal apophysis. The Achilles tendon attaches the triceps surae (calf muscles) to the calcaneus (heel bone). As a child grows the calcaneus grows faster than the surrounding soft tissue, which means the Achilles tendon is pulled uncomfortably tight. This increase in strain causes inflammation and irritation of the calcaneal apophysis (growth plate) which is known as Sever's Disease. The pain is exacerbated by physical activities, especially ones involving running or jumping. Sever's disease most commonly affects boys aged 12 to 14 years and girls aged 10 to 12 years, which corresponds with the early growth spurts of puberty.
Causes
Sever?s disease is most likely to occur during the growth spurt that occurs in adolescence. For girls, growth spurts usually occurs between 8 and 13 years of age. For boys, it?s typically between 10 and 15 years of age. The back of the heel hardens and becomes stronger when it finishes growing, which is why Sever?s rarely occurs in older adolescents and teenagers.
Symptoms
Sharp pain will be present in the affected heel (or both heels), especially while running or walking. Pain can be heightened following activity. The area will be tender to the touch and usually becomes inflamed or reddened. It may also be painful to press on the heel with a finger from the back or to squeeze the sides together; the latter is particularly common. You might notice stiffness in some of the surrounding muscles, making regular movements more difficult to achieve. This and the pain can manifest physically in abnormal practices like tiptoeing or limping. In some cases a lump can be detected on the back of the heel, though it may be so small as to defy detection.
Diagnosis
Sever?s disease can be diagnosed based on your history and symptoms. Clinically, your physiotherapist will perform a "squeeze test" and some other tests to confirm the diagnosis. Some children suffer Sever?s disease even though they do less exercise than other. This indicates that it is not just training volume that is at play. Foot and leg biomechanics are a predisposing factor. The main factors thought to predispose a child to Sever?s disease include a decrease in ankle dorsiflexion, abnormal hind foot motion eg overpronation or supination, tight calf muscles, excessive weight-bearing activities eg running.
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.
