Sever's disease occurs in children when the growth plate (which is the growing part of the heel) is injured. The foot is one of the first body parts to grow to full size. This usually occurs in early
puberty. During this time, bones often grow faster than muscles and tendons. As a result, muscles and tendons become tight. The heel area is less flexible. During weight-bearing activity (activity
performed while standing), the tight heel tendons may put too much pressure at the back of the heel (where the Achilles tendon attaches). This can injure the heel and cause Sever's disease.
Contraction of the calf muscles along with the rapid growth of the leg bone (tibia), decreases ankle motion and increases strain on the heel area. This puts strain on the Achilles tendon. Injury
results from repetitive pulling through the heel bone by the Achilles and the traction forces from the plantar fascia.
The main symptom of sever's disease is pain and tenderness at the back of the heel which is made worse with physical activity. Tenderness will be felt especially if you press in or give the back of
the heel a squeeze from the sides. There may be a lump over the painful area. Another sign is tight calf muscles resulting with reduced range of motion at the ankle. Pain may go away after a period
of rest from sporting activities only to return when the young person goes back to training.
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
The aims are to reduce trauma to the heel, allow rest/recovery and prevent recurrence. Most cases are successfully treated using physiotherapy and exercises, eg to stretch the gastrocnemius-soleus
complex, to mobilise the ankle mortise, subtalar joint and medial forefoot. Soft orthotics or heel cups. Advice on suitable athletic footwear. Other modes of treatment are in severe cases,
temporarily limiting activity such as running and jumping. Ice and non-steroidal anti-inflammatory drugs (NSAIDs), which can reduce pain. In very severe cases, a short period of immobilisation (eg
2-3 weeks in a case in mild equinus position) has been suggested.
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
