NECROSIS (Gr. vEKpos, See also:corpse)  , a See also:term restricted in See also:surgery to See also:death of See also:bone . A severe inflammation, caused by a violent See also:blow, by See also:cold, or by the absorption of various poisons, as See also:mercury and See also:phosphorus, is the See also:general precursor of See also:necrosis . The dead See also:part, analogous to the See also:slough in the soft tissues, is called a sequestrum or exfoliation . At first it is firmly attached to the living bone around; gradually, however, the dead portion is separated from the living See also:tissue . The See also:process of separation is a slow one . New bone is formed around the sequestrum, which often renders its removal difficult . As a See also:rule the surgeon See also:waits until the dead part is loose, and then cuts down through the new See also:case and removes the sequestrum . The cavity in which it See also:lay gradually closes, and a useful See also:limb is the result .
