Also called bedsores, decubitus ulcers, and pressure sores, these wounds form when a patient is bedridden, in a wheelchair or unable to change position at least every two hours. The ulcers usually form where bones are close to the skin — on the back, heels, elbows, hips and ankles. Pressure reduces the blood flow to these areas, which causes the tissue and skin to break down. Difficult-to-heal sores form and increase the risk of life-threatening infection.
