General Discussion
Kohler disease is a rare bone disorder of the foot in children that may be the result of stress-related compression at a critical time during the period of growth. It is characterized by limping caused by pain and swelling in the foot. It most often occurs in children between the ages of three and seven, and it affects males five times more often than it does females. Typically, just one foot is affected.

Children appear to grow out of the disorder, and the affected bones regain their size, density and structure within a year. For some, however, symptoms may last as long as two years.
