Gangrene Decubital

Gangrene of the decubital surface. Description.

Skin gangrene is an inflammation of the skin of the nail phalanx caused by an infectious or non-infectious process. Depending on the cause of occurrence, they distinguish between ichthyosis (septic), simple (aseptic or dry), trophic and erysipelas, in turn, they can also be classified into acute or chronic. The toes and hands, as well as the feet of the lower extremities, are most susceptible to the development of defects due to the fact that the skin in these areas is subject to increased pressure as a result of wearing shoes and the use of sharp objects when walking. The occurrence of gangrene is most often associated with impaired blood supply and innervation.

Here, staphylococcus dies relatively quickly, since the cells of the interfollicular tissue are able to penetrate the epithelial barrier, localizing in the subungual space. The pathological process develops in accordance with the theory of staged inflammation. The severity of the burn phenomena indicates the degree of spread
