Define decubitus ulcer?

A decubitus ulcer, also known as a pressure ulcer or bed sore, is a localized injury to the skin and/or underlying tissue that usually occurs over a bony prominence as a result of pressure, friction, or shear. These ulcers are common in individuals who are bedridden or have limited mobility, as they are unable to change positions frequently, leading to prolonged pressure on certain areas of the body. Decubitus ulcers can range in severity from mild redness to deep wounds that extend into the muscle and bone. Proper wound care and prevention strategies are essential in managing and treating decubitus ulcers.
