Decubitus ulcers, also known as pressure sores, are a condition in which the tissue is compressed, resulting in localized tissue ischemia and necrosis. It is most common in patients who are bedridden for long periods of time or in a compressive position, for example, in patients who are bedridden for long periods of time, and in patients who are lying on their sides for long periods of time, there are bedsores of the greater trochanter of the femur, also called pressure sores. Decubitus ulcers are more common in patients who are thin and have bony protrusions, and in patients who cannot change positions frequently. If the patient cannot be turned and massaged regularly, or if the contact area is under pressure for a long time and does not receive timely blood circulation, the tissues in this area are prone to necrosis, which is the most common problem in the elderly and is called decubitus ulcer.
