wounds or sores of the skin created by pressure on the skin surface that prevents blood flow to the skin surface. They are found in bedridden individuals & those paralyzed from the waist down or from the neck down. Deeper layers are affected before the skin surface but their damage is not visible until there is skin surface breakdown. The skin surface hole is thus described as the tip of an iceberg phenomenon as the full wound is cone shaped. Prevention involves the use of special wheelchair cushions & mattresses as well as changes in position every 2 hours. The treatment for small sores is local wound care. Larger sores require surgical excision of the entire wound & closure with flaps of skin/muscle by a Plastic Surgeon.
