Pressure ulcers (also called bed sores or pressure sores) are injuries caused by constant pressure or friction. They usually affect people who are immobilised or find it difficult to move themselves, for example the elderly or paralysed. Pressure ulcers frequently occur on bony parts of the body, such as the heels and hips, and also on the buttocks. Prolonged pressure on these areas leads to poor circulation, followed by cell death, skin breakdown, and the development of an open wound - the pressure ulcer. Pressure ulcers take a long time to heal - and some do not heal – so, if possible, it is important to prevent them from developing.
