Bed sore (decubitus ulcer)

Bed sore, pressure ulcer, pressure  sores, decubitus ulcer, are names given to the same condition in which there is localised damage to skin and underlying tissue which are usually over a prominence as a result of presure. The most common sites are  sacrum, coccyx, heels, hips, elbows, knees, ankles, back of shoulder, back of cranium. Complete or  partial blockage of blood supply to soft tissue  is the usual cause. Other factors which make the condition more likely to occur include microenvironment in which the tissue is surrounded by wet environment,  reduction in blood flow to tissue in conditions of atherosclerosis, reduction of sensation to the area such as in paralysis or neuropathy, protein calorie malnutrition etc. Age of the patient may slow down the process of healing  to include diabetes mellitus, smoking, atherosclerosis, and the use of anti inflammatory drugs.
