Illustration showing common sites of decubitus ulcers, or bed sores, on an elderly patient. They most commonly occur on soft tissue that covers a bony prominence. While bed sores are treatable if found early, they can become fatal especially in frail elderly patients who may have other factors including compromised healing ability, incontinence, and diabetes or infection. Pressure sores are caused by three different tissue forces - friction, pressure and sheer force.
