Charcot’s foot is a complication of diabetes that almost always occurs in those with neuropathy (nerve damage). When neuropathy is present, the bones in the foot become weakened and can fracture easily, even without there being any major trauma. As the neuropathy is present, the pain goes unnoticed and the person continues to walk on it. This can lead to severe deformities of the foot. As this can be very disabling, early diagnosis and treatment is vitally important.
Another way to consider it – imagine spraining your ankle and not knowing you have done this. You will continue to walk on it – imagine the damage that this would do. This is what happens in a Charcot foot.
