Köhler disease is a (foot) bone disorder in children. It is believed to result from stress-related compression during foetal growth, and it affects males five times more often than it does females. Typically, just one foot is affected, and the condition normally corrects itself within a year. For some, however, symptoms may last as long as two years.
The exact cause of Köhler disease is unknown, though there’s no evidence that it’s hereditary. Some specialists believe that it may be the result of delayed bone formation, leading to structural weakness.
Kohler Disease usually causes pain and swelling in the middle part of the foot, causing the patient to limp as a result. However, symptoms are typically mild, and patients wait until the pain has persisted for a while before seeking treatment.
Treatment usually involves rest, pain relievers and avoiding pressure on the foot. In acute cases, the patient may be fitted with a cast on the foot and lower leg. After the cast is taken off (6-8 weeks later), some patients are prescribed arch support for about 6 months. Moderate exercise is often beneficial, and physical therapy may also help.
