Bedsores are wounds of the body, which are created in places of long-term pressure mainly in elderly people, but also in younger bedsores. Prolapse is due to tissue necrosis in the area under pressure. A recumbency can in some cases appear very quickly. Even during e.g. 2 days in a supine position in an elderly patient, recumbency may occur. Prolapses occur more often at older ages, and tissue perfusion is worse at older ages. Swelling often occurs in the area of the coccyx, heels, hips, and other parts of the body. In a recumbency, as mentioned there are dead tissues (necrosis). Tissue necrosis usually rapidly expands in width and depth, and an abscess (collection of pus) may form. In neglected cases it is possible to spread the inflammation even to the bones of the lying area. In this case, an X-ray or CT scan is required to detect any osteolysis.
