Overview
Sever?s disease is also known as calcaneal apophysitis, which is a medical condition that causes heel pain In one or both feet. The disease is known to affect children between the ages of 8 and 14. Sever?s disease occurs when part of the child?s heel known as the growth plate (calcaneal epiphysis) is attached to the Achilles tendon. This area can suffer injury when the muscles and tendons of the growing foot do not keep pace with bone growth. Therefore, the constant pain which one experiences at the back of the heel will make the child unable to put any weight on the heel. The child is then forced to walk on their toes. Toe gait- develops in which the child must change the way they walk to avoid placing weight on the heel. This can lead to other problems as well in the future.
Causes
The calcaneal apophysis develops as an independent center of ossification (possibly multiple). It appears in boys aged 9-10 years and fuses by age 17 years, it appears in girls at slightly younger ages. During the rapid growth surrounding puberty, the apophyseal line appears to be weakened further because of increased fragile calcified cartilage. Microfractures are believed to occur because of shear stress leading to the normal progression of fracture healing. This theory explains the clinical picture and the radiographic appearance of resorption, fragmentation, and increased sclerosis leading to eventual union. The radiographs showing fragmentation of the apophysis are not diagnostic, because multiple centers of ossification may exist in the normal apophysis, as noted. However, the degree of involvement in children displaying the clinical symptoms of Sever disease appears to be more pronounced. In a study of 56 male students from a soccer academy, of whom 28 had Sever disease and 28 were healthy control subjects, findings suggested that higher heel plantar pressures under dynamic and static conditions were associated with Sever disease, though it was not established whether the elevated pressures predisposed to or resulted from the disease. Gastrocnemius ankle equinus also appeared to be a predisposing factor.
Symptoms
The most common symptoms of Sever?s involves pain or tenderness in one or both heels. This pain usually occurs at the back of the heel, but can also extend to the sides and bottom of the heel. A child with Sever?s may also have these common problems, Heel pain with limping, especially after running. Difficulty walking, Discomfort or stiffness in the feet upon awaking. Swelling and redness in the heel, Symptoms are usually worse during or after activity and get better with rest.
Diagnosis
A physical exam of the heel will show tenderness over the back of the heel but not in the Achilles tendon or plantar fascia. There may be tightness in the calf muscle, which contributes to tension on the heel. The tendons in the heel get stretched more in patients with flat feet. There is greater impact force on the heels of athletes with a high-arched, rigid foot.
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.
Recovery
It may take several weeks or months for the pain to completely stop. In most cases severs disease goes away on its own with a little rest and time. However if you ignore the pain and play through it, the condition may get worse and may be more difficult to treat. When the pain is completely gone, you can slowly return to your previous level of activity. With future growth spurts the pain may return therefore keep up with the stretches and follow the advice given.
