Classification of wounds of the diabetic foot.

Abstract

A classification system should be thought of as a diagnostic language. Ideally, this language should be used by a large, diverse population of clinicians to guide therapy and ultimately predict outcome. The diabetic foot ulcer is widely known to be the prime precipitant of lower extremity amputations. Its description and classification is the first step toward widespread standardization of treatment and prevention. This article chronologically describes the major diabetic foot wound classification systems devised over the previous generation, discussing each of their attributes and their shortcomings, with an emphasis on an evidence basis for care. It is our hope that discussions such as this one will ultimately lead to a diagnostic and therapeutic lingua franca for diabetic foot wounds and a commensurate reduction in the unconscionably high prevalence of amputations, which we now currently face.
