A review of Charcot neuroarthropathy of the midfoot and hindfoot: what every radiologist needs to know.

Charcot neuroarthropathy (CN) occurs commonly in diabetic patients in the joints of the foot and ankle. Radiologists may be the first to suggest the diagnosis of CN and can facilitate prompt intervention and treatment if they are aware of the radiographic manifestations of CN and the signs of progression of disease. Radiologists should also become aware of the evolving treatment of the disease as focus is shifting toward early surgical intervention and limb salvage rather than amputation. Knowledge of preoperative assessment, the types of surgeries performed, and some of the encountered postoperative complications enable the radiologist to facilitate timely intervention by our surgical colleagues and be a valuable member of the management team.
