What is New About Pressure Ulcers?

Pressure sores, pressure ulcers, pressure wounds, decubitus ulcers bedsores all names of what we commonly include as skin breakdown. These wounds and their terms have been around for a long time – so what is new?

Here is a new term – Deep Tissue Injury (DTI). In several articles published in Mobility Management in 2014 there is new light on tissue deformation and how this internal deformation can cause Deep Tissue Injuries that can be even more insidious than traditional pressure ulcers. DTI is harder to identify and observe than the typical pressure ulcer. Research by Amit Gefen, Ph.D. and professor of biomedical engineering at Tel Aviv University has adopted an unconventional, but very effective approach to understanding the forces from within the body that eventually lead to skin breakdown.

What is a Pressure Wound?

A pressure wound is known by various names: pressure sore, pressure ulcer, decubitus ulcer and skin breakdown – to name a few. It is an injury to the skin and/or tissues under the skin. Constant pressure on an area of skin reduces blood supply to the area. Over time, it can cause the skin to break down and form an open sore or ulcer. Pressure wounds are more likely to occur if an individual is confined to a bed or wheelchair.

Pressure sores most often form on the skin over bony areas where there is little cushion between the bone and the skin. Most pressure sores form on the lower part of the body, including over the tailbone and on the back along the spine, on the buttocks and on the hips. They also can form in other areas of the body such as the heels or back of the head – wherever constant pressure is exerted on the skin. For the purposes of this article, we will focus our attention to the pressure wounds that can occur at the tailbone (coccyx) and the butt bones (ischial tuberosity’s).
