Between June of 1987 and August 1988 we evaluated 31 diabetic patients hospitalized for severe foot infections to determine the etiologic agents, the value of the bacteriologic samples obtained, the benefits of conservative surgery and variable predictors of a major amputation. Sixteen patients suffered from necrosis, 16 osteomyelitis, 14 ulcers, 5 cellulitis, and/or abscesses and 22 had vascular compromise. Samples were taken from these infections excluding necrotic material. We isolate 76 microorganisms (2.4/pt), 57% Gram-positive cocci (predominantly S. aureus and enterococci), and 43% Gram-negative bacilli. Anaerobes were not isolated probably secondary to the exclusion of necrotic samples. There was high incidence of skin and soft tissue sampling (79%) bone (13/16) and surgical curettage (11/11). In 9 patients the correlation of soft tissue sampling and bone sampling was assessed with a positive correlation with respect to Gram-positive cocci. Twenty-one patients required conservative surgeries of the foot (9 underwent revascularization), 67% of which avoided a mayor amputation. However no significant variables predictive of a major amputation were detected in this study. In summary, the conservative surgery allowed to 2 out of 3 patients to preserve the foot.
