ABSTRACT

 In 1908, Alban Kohler was the first person to describe the condition now known as Kohler’s disease, which is avascular necrosis of the navicular bone in the foot. Kohler’s illness is a condition that only affects children and young adults. The navicular bone’s pressure before its ossification is assumed to be the root cause of the condition, although its genesis is not completely understood; this results in blood flow irregularities, leading to avascular necrosis. Males between the ages of 4 and 7 are more likely to be affected by Kohler’s disease. In most cases, Kohler’s disease affects only one side of the body; however, one study indicated that 25% of cases of Kohler’s disease affect both sides of the body. Patients will often appear with symptoms including pain on the medial side of the foot, inflammation on the medial foot, and/or a limp. On plain films, the navicular will exhibit typical signs of avascular necrosis, such as sclerosis, disintegration, and flattening of the bone. This condition is caused by the death of blood vessels. The prognosis is very favorable for patients with the self-limiting syndrome known as Kohler’s disease. There have been no examples of Kohler’s disease that have developed into long-term clinical or radiographic problems recorded.
