Sever's disease, also known as calcaneal apophysitis, is a medical condition that causes heel pain in one or both feet of children during the period when their feet are growing. Sever's disease occurs most commonly in boys and girls between the ages of 8 and 14 years of age. Sever's disease occurs when the part of the child's heel known as the growth plate, or the calcaneal epiphysis, an area attached to the Achilles tendon, suffers an injury or when the muscles and tendons of the growing foot do not keep pace with bone growth. The result is constant pain experienced at the back of the heel and the inability to put any weight on the heel, forcing the child to bear weight on their toes while walking. A toe gait develops in which the child must change the way they walk to avoid placing weight on the painful heel, a position that can lead to other developmental problems.
Sever's Disease is a repetitive strain injury caused by the following. High impact injury activities and sport like netball, football, soccer, hockey, basketball, running, jumping and tennis. Tight calf muscles. Poor mechanics, structure and function of the foot. Excessive pronation. Rapid growth spurt. The above causes tension, inflammation and pain where the Achilles tendon inserts onto the calcaneus (Back/bottom surface of the heel bone). It is important that this problem is treated and monitored until the growth plate ossifies in the heel. This could occur between the ages of 14 and 16 years of age. In extreme cases the growth plate can become separated from the calcaneus.
Unilateral or bilateral heel pain. Heel pain during physical exercise, especially activities that require running or jumping. Increased pain level after exercise. A tender swelling or bulge on the heel that is painful on touch. Limping. Calf muscle stiffness first thing in the morning.
A Podiatrist can easily evaluate your child?s feet, to identify if a problem exists. Through testing the muscular flexibility. If there is a problem, a treatment plan can be create to address the issue. At the initial treatment to control movement or to support the area we may use temporary padding and strapping and depending on how successful the treatment is, a long-term treatment plan will be arranged. This long-term treatment plan may or may not involve heel raises, foot supports, muscle strengthening and or stretching.
Non Surgical Treatment
First, your child should cut down or stop any activity that causes heel pain. Apply ice to the injured heel for 25 minutes three times a day. Your child should not go barefoot. If your child has severe heel pain, ibuprofen (Advil) will help. It is important that your child performs exercises to stretch the hamstring and calf muscles, and the tendons on the back of the leg. The child should do these stretches five times each, two or three times a day. Each stretch should be held for 20 seconds. Your child also needs to do exercises to strengthen the muscles on the front of the shin. To do this, have your child stand facing a wall to stretch the calves and the heel cord. Place one foot a shoulder?s width in front of the other, both feet facing the wall. The front knee is bent and the back knee is straight during the calf stretch. Then have your child push against the wall and feel the stretch in his or her back leg. To stretch out the heel cord, have him or her stay in the same position and bend the back knee. Repeat three times. Practice this stretch twice daily.
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.
