title: Diabetic foot ulcers: pathogenesis and management.
abstract: Foot ulcers are a significant complication of diabetes mellitus and often precede lower-extremity amputation. The most frequent underlying etiologies are neuropathy, trauma, deformity, high plantar pressures, and peripheral arterial disease. Thorough and systematic evaluation and categorization of foot ulcers help guide appropriate treatment. The Wagner and University of Texas systems are the ones most frequently used for classification of foot ulcers, and the stage is indicative of prognosis. Pressure relief using total contact casts, removable cast walkers, or "half shoes" is the mainstay of initial treatment. Sharp debridement and management of underlying infection and ischemia are also critical in the care of foot ulcers. Prompt and aggressive treatment of diabetic foot ulcers can often prevent exacerbation of the problem and eliminate the potential for amputation. The aim of therapy should be early intervention to allow prompt healing of the lesion and prevent recurrence once it is healed. Multidisciplinary management programs that focus on prevention, education, regular foot examinations, aggressive intervention, and optimal use of therapeutic footwear have demonstrated significant reductions in the incidence of lower-extremity amputations.
