Charcot’s neuroarthropathy is a relatively common disease in patients with diabetic neuropathy. If unrecognized or left untreated, Charcot’s neuroarthropathy can result in a severely misshapen and unstable foot and ankle. Ulceration, soft-tissue infection, and osteomyelitis frequently ensue, and partial or complete amputation of the foot is not uncommon. A high index of suspicion and proper interpretation of clinical and diagnostic findings are essential to establish a timely and accurate diagnosis and to institute appropriate treatment. The pathogenesis of neuroarthropathy is reviewed and diagnosis and treatment of the stage 0 diabetic Charcot foot are presented. (J Am Podiatr Med Assoc 92(4): 210-220, 2002)
