The Charcot foot in diabetes: six key points.

The Charcot foot commonly goes unrecognized, particularly in the acute phase, until severe complications occur. Early recognition and diagnosis, immediate immobilization and a lifelong program of preventive care can minimize the morbidity associated with this potentially devastating complication of diabetic neuropathy. If unrecognized or improperly managed, the Charcot foot can have disastrous consequences, including amputation. The acute Charcot foot is usually painless and may mimic cellulitis or deep venous thrombosis. Although the initial radiograph may be normal, making diagnosis difficult, immediate detection and immobilization of the foot are essential in the management of the Charcot foot. A lifelong program of patient education, protective footwear and routine foot care is required to prevent complications such as foot ulceration.
