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.

Prevalence differs depending on the severity of diabetes mellitus 1 :. Patients present insidiously or are identified incidentally, or as a result of investigation for deformities. Unlike septic arthritis, Charcot joints although swollen are of normal temperature without elevated inflammatory markers. Importantly, they are painless. The pathogenesis of a Charcot joint is thought to be an inflammatory response from a minor injury that results in osteolysis. In the setting of peripheral neuropathy, both the initial insult and inflammatory response are not well appreciated, allowing ongoing inflammation and injury 1. There are two patterns of Charcot joint: atrophic and hypertrophic. Sensorimotor and autonomic neuropathies of various etiologies are the primary predisposing factors.

A nonsmoking, man with no previous comorbidities, attended to us for painless inflammation and edema of left ankle and foot for at least 7 months, without fever or other joint swellings. There was no history of trauma. He was seen in the emergency department 2 months ago, he was diagnosed with cellulitis and oral antibiotics were prescribed. Physical examination revealed edematous, hyperemic leg and foot, with absent arch mid-foot collapse , hyperpigmentation, and calluses at pressure points. He had undiagnosed diabetes. White arrow: There is an increased joint space between metatarsal bone I and II indicating Lisfranc's joint dislocation with lateral displacement of the metatarsal bones. Navicular Yellow and medial cuneiform Red are dislocated The navicular cuneiform joint is dislocated medially. Blue arrow : Erosion of the lateral surface of the lateral cuneiform and 5 th metatarsal base. Charcot neuroarthropathy is a progressive, noninfectious, destructive inflammatory process of joints associated with a deficit of pain sensation and proprioception. At the foot and the ankle, diabete s and polyneuropathy are the most frequent causes 1.

During the less active or inactive phase, the foot is not red any more, but some soft tissue and bone marrow edema may last. Current state-of-the art treatment is the off-loading of the affected foot—as soon as possible—so that the mentioned four disease stages run-through while the foot is protected from major shape changes Fig. Table 1 MRI features for differentiating an active Charcot foot from osteomyelitis. Furthermore, the enhancement pattern in DCE-perfusion seems to be different between osteomyelitis and osteoarthropathic changes, increasing the potential of differencing lesions with bone marrow edema [ 30 ]. This might take up to 18 months [ 4 ].
