Kohlerâs disease is a rare condition in which the tarsal navicular bone (a bone in the arch of the foot) becomes inflamed. This bone disease is named after the German radiologist who described the condition in the early twentieth century. Kohlerâs disease usually affects children between the ages of three and five. It occurs more commonly in boys than in girls, and is often unilateral, affecting one foot. It is described as an avascular necrosis, or osteonecrosis, in which bone tissue deteriorates due to an interruption of blood supply.
