[Charcot arthropathy and diabetic foot].

Diabetes mellitus is a major chronic degenerative disease, which currently is taking on alarming proportions in the population of our country. Neuropathic arthropathy is one of the most interesting degenerative joint disorders and increasingly common within the orthopedic pathology. It is defined as a progressive degenerative arthropathy, chronic and affecting one or more peripheral joints, and develops as a result of the lack of sensory perception normal in the innervation of joints. As a result the joints of the feet are subjected to trauma and repetitive injury causing a neurotraumatic effect with progressive damage to the joints of the hindfoot, midfoot and forefoot. Diagnosis includes a proper medical history, careful examination of the affected limb, conventional X-ray, scintigraphy, computed tomography and magnetic resonance imaging in some cases. Conservative treatment includes: drugs, rest of the affected limb, and the use of appliances like total-contact cast, orthotics or special shoes. Surgical treatment depends on the stage of the disease, and may require one or more surgical procedures, in order to achieve a full foot plantar support to prevent ulcers. One of the surgeries performed most often is the fusion of damaged joints. Surgery must be performed only in the coalescence phase of the disease, using internal, or external fixation or both.
