Kohler’s disease is a rare bone disorder affecting young children. It’s more prevalent among boys, but girls can suffer from it, as well. Those with Kohler’s disease experience abnormal growth of foot arteries that supply blood to the bones. This can weaken the foot bones and make them more vulnerable to fractures and other injuries. It also causes pain in the mid-foot area, and children will sometimes limp as a result of the discomfort. Treatment is focused on resting the affected foot, the use of a cast or braces, and mild painkillers while healing takes place. Most cases are resolved within 18-24 months.
