It is important to recongnize that the finding of Clostridia in a wound does not establish the diagnosis of gas gangrene. Clostridia may be present in traumatic wound under three circumstances: (1) simple contamination, (2) anaerobic cellulitis, and (3) gas gangrene. Confusion between clostridial cellulitis and gas gangrene may be avoided by remembering that clostrdial cellulitis is not associated with muscle invasion, and seldom produce swelling, pain, toxemia, or shock. Authors had been treated a case of clostridial infection with a vascularized groin flap followed by good result.
