Sever's Disease is one of the most common causes of heel pain in active adolescents. Hip stability is restored using a non-surgical positioning device. Symptoms of Sever's disease are relieved
through a combination of conservative treatment options and preventative measures can be taken to decrease the risk of developing the condition.
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.
This is a condition that affects the cartilage growth plate and the separate island of growing bone on the back of the heel bone. This growth plate is called the physeal plate. The island of growing
bone is called the apophysis. It has the insertion attachment of the Achilles tendon, and the attachment of the plantar fascia. This island of bone is under traction from both of these soft tissue
tendon and tendon-like attachments.
A doctor can usually tell that a child has Sever's disease based on the symptoms reported. To confirm the diagnosis, the doctor will probably examine the heels and ask about the child's activity
level and participation in sports. The doctor might also use the squeeze test, squeezing the back part of the heel from both sides at the same time to see if doing so causes pain. The doctor might
also ask the child to stand on tiptoes to see if that position causes pain. Although imaging tests such as X-rays generally are not that helpful in diagnosing Sever's disease, some doctors order them
to rule out other problems, such as fractures. Sever's disease cannot be seen on an X-ray.
Non Surgical Treatment
Treatment includes modifying activities and resting to reduce pain and inflammation and take pressure off the growth center. Ice can also be very helpful in relieving symptoms, as well as
anti-inflammatory medication. A physical therapy program should be initiated to stretch tight calf muscles and strengthen the ankle muscles to relieve tension on the growth center. Shoes with padded
heel surfaces and good arch support can decrease pain. Cleats may need to be avoided for some time to help reduce symptoms. The doctor may also recommend gel heel cups or supportive shoe
The surgeon may select one or more of the following options to treat calcaneal apophysitis. Reduce activity. The child needs to reduce or stop any activity that causes pain. Support the heel.
Temporary shoe inserts or custom orthotic devices may provide support for the heel. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and
inflammation. Physical therapy. Stretching or physical therapy modalities are sometimes used to promote healing of the inflamed issue. Immobilization. In some severe cases of pediatric heel pain, a
cast may be used to promote healing while keeping the foot and ankle totally immobile. Often heel pain in children returns after it has been treated because the heel bone is still growing. Recurrence
of heel pain may be a sign of calcaneal apophysitis, or it may indicate a different problem. If your child has a repeat bout of heel pain, be sure to make an appointment with your foot and ankle
