Charcot foot pied de Charcot CF , first described by Jean-Martin Charcot in , is caused by a wide variety of disorders that ultimately destroy the protective mechanisms of the small joints of the foot. Leprosy and diabetes are the most common causes of this form of destructive neuroarthropathy in the developing world. If the diagnosis is missed early in the natural course of the disease, severe foot deformity and disability, ulceration, infection, and ultimately limb amputation are the expected outcomes.

Charcot foot refers to an inflammatory pedal disease based on polyneuropathy; the detailed pathomechanism of the disease is still unclear. Patients with Charcot foot typically present in their fifties or sixties and most of them have had diabetes mellitus for at least 10 years. If left untreated, the disease leads to massive foot deformation. This review discusses the typical course of Charcot foot disease including radiographic and MR imaging findings for diagnosis, treatment, and detection of complications. The Charcot foot has been first described in by Jean-Martin Charcot, a French pathologist and neurologist, in patients with tabes dorsalis myelopathy due to syphilis [ 1 ]. The detailed pathomechanisms of this disease still remain unclear: there is consensus that the cause is multifactorial and that polyneuropathy reduced pain sensation and proprioception is the underlying basic condition of this disease. In industrialized countries, diabetes mellitus is the main cause of polyneuropathy in the lower limb [ 2 ]—much more common than other causes like alcohol abuse or malnutrition. The prevalence of Charcot foot in a general diabetic population is estimated between 0. The risk of getting a Charcot foot is not related to the type I or II of diabetes mellitus. Patients with Charcot foot typically present within their fifties or sixties and most of them have had diabetes mellitus for at least 10 years [ 2 ].
