Ulcer

Decubitus ulcer or bed sore is a type of sore which is developed on portions of body which have immediate contact with force and pressure contact with surfaces.
The inflammation and rough ruptures on sacrum, elbows, knees and ankles are the targeted areas, where the wear and tear often occurs, and boils are developed. The odontoid and cartilaginous areas of body which experience the major strain are prone to this type of sores. Decubitus ulcers are also caused due to the side effects of adverse drug therapy and its allergic drug interference. The sores are affected by deep piercing and shear straining of tissues, causing less oxygen, impaired blood supply, and consequent necrosis in the particular loci.
The photos of pressure ulcers show in certain cases that they are open sores and are the environmental adverse conditions affect the sore to greater extent.
There are two levels of operation in case of decubitus ulcer the deep generative theory and the top to bottom lesion theory. In the former case the sore starts at bottom level and comes to upper surface, in latter case the sore starts at epidermis and is impregnated into deep levels of dermis up to blood vessel surface.
The treatment of decubitus ulcer relates to the conventional treatment of negative pressure theory where counter pressure is developed where the wound is covered by the air tight seal and consequently the dead matter the exudates are removed and helps the body to produce granular tissue which leads to the formation of new dermal cells and hence forth closing the sore cavity.
