Hallmarks of amputation surgery.

From the Hippocratic era until currently, the surgical approach to amputation has changed little. However, the indications for amputations have changed a lot and had been refined, especially in diabetic patients and in those with severe chronic peripheral vascular disease. An exponential decrease in mortality for an operation once fraught with complications was due to the development of the tourniquet, proper vessel ligation and repair, antisepsis, and anesthesia.
