Pressure ulcers, also known as pressure sores, bedsores, and decubitus ulcers, are localized injuries to the skin and/or underlying tissue that usually occur over a bony prominence as a result of pressure, or pressure in combination with shear and/or friction.
The most common sites are the skin overlying the sacrum, coccyx, heels, and hips, but other sites such as the elbows, knees, ankles, or the back of the cranium can be affected. Pressure ulcers may range in severity from superficial redness to deep tissue damage and can be life-threatening if left untreated. Treatment usually involves off-loading the area of pressure, providing appropriate wound care, and preventing further injury.
