Pressure Ulcers of the Lower Limb
- First Online:
Pressure ulcers are a type of injury that breaks down the skin and underlying tissue when an area of skin is placed under constant pressure for certain period of time causing tissue ischemia, cessation of nutrition and oxygen supply to the tissues, and eventually tissue necrosis. Constant pressure resulting in “distortion or deformation damage” is probably the most accurate description of a pressure ulcer . Pressure ulcers can range in severity from patches of discolored skin to open wounds that expose the underlying muscles, bones, and joints.
