Calcaneal Apophysitis (Sever's Disease)

Foot and ankle problems usually fall into the following categories:

  • Acquired from improper footwear, physical stress, or small mechanical changes within the foot.
  • Arthritic foot problems, which typically involve one or more joint.
  • Congenital foot problems, which occur at birth, are generally inherited.
  • Infectious foot problems, which are caused by bacterial, viral, or fungal disorders.
  • Neoplastic disorders, usually called tumors, which are the result of abnormal growth of tissue and may be benign or malignant.
  • Traumatic foot problems, which are associated with foot and ankle injuries.

What Is Calcaneal Apophysitis?
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.

 

Calcaneal278Calcaneal 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.

Causes
Overuse and stress on the heel bone through participation in sports is a major cause of calcaneal apophysitis. The heel’s growth plate is sensitive to repeated running and pounding on hard surfaces, resulting in muscle strain and inflamed tissue. For this reason, children and adolescents involved in soccer, track, or basketball are especially vulnerable.

Other potential causes of calcaneal apophysitis include obesity, a tight Achilles tendon, and biomechanical problems such as flatfoot or a high-arched foot.

Symptoms
Symptoms of calcaneal apophysitis may include:

  • Pain in the back or bottom of the heel
  • Limping
  • Walking on toes
  • Difficulty running, jumping, or participating in usual activities or sports
  • Pain when the sides of the heel are squeezed

Diagnosis
To diagnose the cause of the child’s heel pain and rule out other more serious conditions, the foot and ankle surgeon obtains a thorough medical history and asks questions about recent activities. The surgeon will also examine the child’s foot and leg. X-rays are often used to evaluate the condition. Other advanced imaging studies and laboratory tests may also be ordered.

Treatment
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 surgeon.

Can Calcaneal Apophysitis Be Prevented?
The chances of a child developing heel pain can be reduced by:

  • Avoiding obesity
  • Choosing well-constructed, supportive shoes that are appropriate for the child’s activity
  • Avoiding or limiting wearing of cleated athletic shoes
  • Avoiding activity beyond a child’s ability.
