Final answer:
A bedsore, also known as a decubitis ulcer, is a skin disorder that occurs in bedridden individuals due to long-term, unrelieved pressure on the skin.
Step-by-step explanation:
The skin disorder that can occur in people who are bedridden is called a bedsore, also known as a decubitis ulcer. Bedsores result from constant, long-term, unrelieved pressure on certain parts of the body, typically bony areas, which causes a reduction in blood flow and can lead to necrosis or tissue death. This skin disorder is most commonly found in the elderly or those with conditions that lead to prolonged immobility. Healthcare facilities usually implement measures such as turning patients every few hours to prevent the development of bedsores. Untreated bedsores can become infected and may even be fatal.
