Dry gangrene
A patient found themselves in a distressing situation when both of their hands became trapped in the car's hood for a half-hour before receiving assistance. Unfortunately, as a consequence of this ordeal, the fifth finger experienced dry gangrene and had to be surgically removed. Dry gangrene is a manifestation of coagulative necrosis that arises in tissue deprived of adequate blood supply, often due to underlying medical conditions. It is not an ailment in itself but rather a symptom of other health issues. The afflicted area typically appears dry, contracted, and takes on a dark reddish-black hue. The natural course of dry gangrene usually leads to complete separation, with the affected tissue eventually falling off if not addressed through surgical removal, a process referred to as autoamputation.
