Abstract
Diabetes is associated with various complications and reduced quality of life. Of the many complications, some are life-threatening. Among these, foot complications remain an important concern. The major foot complications include foot ulceration, cellulitis, abscess, wet gangrene, dry gangrene, and necrotizing fasciitis, with different pathophysiological concepts behind each of them. Gangrene occurs due to reduced blood supply in the body tissues that leads to necrosis. This condition may arise because of an injury, infection, or other health conditions, majorly diabetes. Gangrene is classified as dry, wet, and gas gangrene. In case of wet and gas gangrene, surgical amputation is usually performed to prevent the spread of infection to other tissues. In dry gangrene, due to the presence of clear demarcation, autoamputation is preferred in certain parts of the globe. The present review aims to analyze the mode of dry gangrene management in diabetic patients based on previous evidence and plans to highlight various management strategies available for dry gangrene and the advantages/disadvantages of different treatments with special consideration to autoamputation.
