Edge of Wound- Monitoring Healing. In a wound that is healing normally, new skin cells are formed and added to the edges and the base until it closes up. In many chronic wounds, this does not happen and the wound fails to close. Reasons for this include abnormal skin cells at the edges and base of the wound, or inhibitory factors in the wound exudate (fluid). In Diabetic ulcers or Pressure injuries, the wound edge may be worn away or damaged (i.e. undermined) so that new skin cells cannot attach properly.
Stab wound: injury from sharp weapon that is deeper than it is wide. 1  Common weapons include knife, ice pick, scissors, fork. 2  Stab wound on the skin should be examined to determine if it has sharp or blunt margins; this can be used to determine if the weapon had a single edged or double edged blade.
