Sever's disease, also called calcaneal apophysitis, is a painful bone disorder that results from inflammation (swelling) of the growth plate in the heel. A growth plate, also called an epiphyseal plate, is an area at the end of a developing bone where cartilage cells change over time into bone cells. As this occurs, the growth plates expand and unite, which is how bones grow.
The pain of Severs usually occurs because of inflammation and micro-trauma to the growth plate of the heel bone. This can be caused by a sudden increase in activity, running on very hard surfaces, a growth spurt, tight muscles or feet that roll in.
The most common symptoms of Sever?s involves pain or tenderness in one or both heels. This pain usually occurs at the back of the heel, but can also extend to the sides and bottom of the heel. A child with Sever?s may also have these common problems, Heel pain with limping, especially after running. Difficulty walking, Discomfort or stiffness in the feet upon awaking. Swelling and redness in the heel, Symptoms are usually worse during or after activity and get better with rest.
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.
Non Surgical Treatment
Activity Modification: to decrease the pain, limiting sporting activities is essential. Cutting back on the duration, intensity, and frequency can significantly improve symptoms. Heel cord stretching is important if heel cord tightness is present. Heel cushions/cups or soft orthotics decreases the impact on the calcaneus by distributing and cushioning the weight bearing of the heel. Use of NSAIDS. Ibuprofen (Nuprin, Motrin) or naproxen (Aleve) can decrease pain and secondary swelling. Ice. Placing cold or ice packs onto the painful heel can alleviate pain. Short-leg cast. For recalcitrant symptoms a short-leg cast is occasionally used to force rest the heel.
