Deep Tissue Injury


(Depending on size)

  • Deep tissue injuries can have the same outward appearance as decubitus ulcers, but the underlying etiology is different. These injuries happen and progress quickly.
  • The mechanism of this injury is pressure to the skin and soft tissue, within a short period of time, that compromises tissue perfusion and results in ischemia and damage to the deeper subcutaneous tissues.
  • The initial injury is not visible on the surface of the skin and only manifests later as the underlying tissue starts to necrose, first forming what appears to be a bruise before progressing to an external/visible skin wound.
  • This type of wound evolves upward towards the skin as well as deeper, so once the external wound becomes apparent, it is frequently already a deep injury often with the appearance of a Stage 3–4 decubitus ulcer.
