What is the medical term for pressure ulcers caused by skin deterioration due to prolonged pressure?

The term "decubitus ulcer" is the medically recognized term for pressure ulcers that occur due to prolonged pressure on the skin, commonly seen in individuals who are bedridden or have limited mobility. This condition develops when blood flow to a specific area of the skin is restricted for an extended period, leading to tissue damage and ulceration.

The use of "decubitus" specifically refers to the position of the body when these ulcers typically occur, often related to lying down or being in a fixed position for a long time. The other options, while frequently used in clinical settings, are more general or colloquial. "Bed sore" and "pressure sore" are common terms for the same condition, but "decubitus ulcer" is the accurate medical terminology that encompasses all aspects of the condition's definition and etiology. "Surface ulcer" does not specifically relate to the context of pressure and does not accurately describe the nature of the injury related to prolonged pressure as effectively as "decubitus ulcer."
