Kohler disease (or "Köhler") is a rare bone disorder of the foot found in children between six and nine years of age. It was first described in 1908 by Alban Kohler (1874-1947), a German physician. It is caused when the navicular bone temporarily loses its blood supply. As a result, tissue in the bone dies and the bone collapses. When treated, it causes no long term problems. As the navicular bone gets back to normal, symptoms typically abate.

[edit] Symptoms
Sufferers experience pain and swelling in the middle part of the foot and usually limp as a result. The disease typically affects boys, but it can also affect girls. Five is the age of boys most often affected and patients often complain of pain over the apex. X-ray of both feet is used to diagnose disease. The affected foot has dense flattened navicular bone.
[edit] Causes
Although no definitive cause has been found yet, the disease may be due to strain on a weak navicular bone.
[edit] Treatment
The patient is often fit with a cast that stops below the knee. Moderate exercise is often beneficial.
