Pressure ulceration grade 3

**Definition:** Pressure ulcer with full thickness skin loss. Subcutaneous fat may be visible but bone, tendon or muscle are not exposed. Slough may be present but does not obscure the depth of tissue loss. There may be undermining and tunnelling into adjacent structures. The depth varies by anatomical location: grade 3 pressure ulcers can be shallow in areas with little or no subcutaneous fat (e.g. bridge of the nose, ear, occiput and malleolus). In contrast, grade 3 pressure ulcers can be extremely deep in areas of significant adiposity.

**Inclusions:** - pressure injury stage 3 with full thickness skin loss
