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.

One neuropathic joint radiology used method is the treatment of patients with custom-made removable total contact casts Fig. Furthermore, CT and PET-CT may be used as an alternative cross-section imaging tool in patients with contraindications for MR examination pacemaker, severe claustrophobia, etc.

At the time the article was last revised Mohammadtaghi Niknejad had no financial relationships to ineligible companies to disclose. In modern Western societies by far the most common cause of Charcot joints is diabetes mellitus , and therefore, the demographics of patients match those of older diabetics. 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.

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.

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.

Clinical and radiological examinations were suggestive of osteomyelitis of the left great toe. Charcot foot is characterized by four different disease stages Fig. At the time the article was created The Radswiki had no recorded disclosures. Acknowledgements This work was not sponsored by grants or any funding organization or company. Conclusion The Charcot foot is a rare disease, associated with polyneuropathy, in industrialized countries most commonly seen in the long-term diabetic population. Treatment 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. The pathogenesis of a Charcot joint is thought to be an inflammatory response from a minor injury that results in osteolysis. These patterns can be present in isolation or in combination. Neuropathic arthropathy of the foot with and without superimposed osteomyelitis: MR imaging characteristics. Bone marrow edema can be present very common in middle-stage Charcot foot or absent, depending on disease activity. Christian W. Zone I: metatarsophalangeal and interphalangeal joints, zone II: tarsometatarsal joints, zone III: tarsal joints, zone IV: ankle and subtalar joints, and zone V: calcaneus. Establishing an early diagnosis and therefore an early off-loading treatment is crucial for the prognosis and outcome of an acute Charcot foot.
