Infections of the diabetic foot

Diabetic foot infections are frequently much worse than the initial clinical appearance would indicate. Altered immune response, peripheral vascular disease, and neuropathy are key factors in the production of infection. Treatment must be based upon careful bacteriologic analysis and individualized antibiotic therapy. Surgical debridement, when indicated, is the mainstay of treatment. Partial foot amputation and salvage are always preferred over higher amputation when possible.
