Sever's Disease, also known as calcaneal apophysitis, is a disease of the growth plate of the bone and is characterized by pain in the heel of a child's foot, typically brought on by some form of injury or trauma. This condition is most common in children ages 10 to 15 and is frequently seen in active soccer, football, or baseball players. Sport shoes with cleats are also known to aggravate the condition. The disease mimics Achilles tendonitis, an inflammation of the tendon attached to the back of the heel. A tight Achilles tendon contributes to Sever's Disease by pulling excessively on the growth plate of the heel bone (calcaneus). Treatment includes cutting back on sports activities, calf muscle stretching exercises, heel cushions in the shoes, icing, and/or anti-inflammatory medications.
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.
Sever?s disease is a clinical diagnosis based on the youth?s presenting symptoms, rather than on diagnostic tests. While x-rays may be ordered in the process of diagnosing the disease, they are used primarily to rule out bone fractures or other bone abnormalities, rather than to confirm the disease. Common Characteristics of Sever?s Disease include Posterior inferior heel pain. Pain is usually absent when waking in the morning. Increased pain with weight bearing, running, or jumping (or activity-related pain). Area often feels stiff or inflexible. Youth may limp at the end of physical activity. Tenderness at the insertion of the tendons. Limited ankle dorsiflexion range that is secondary to tightness of the Achilles tendon. Activity or sport practices on hard surfaces can also contribute to pain, as well as poor quality shoes, worn out shoes, or the wrong shoes for the sport. Typically, the pain from this disease gradually resolves with rest.
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
Orthotics or special shoe inserts can also be used to cushion the heel and reduce pain. Physical Therapy. If avoiding physical activities fails to clear up Sever?s disease Genesis Orthopedics & Sports Medicine may proceed with physical therapy. Physical therapy strengthens the muscles and tendons in the heel, releasing pressure and eventually reducing pain.
Because there are several theories as to the actual cause of the disease, there is no definitive answer on prevention. Experts agree, though, that youth athletes can help minimize the risk of Sever's disease by maintaining good joint and muscle flexibility while engaging in sports or physical activities.
