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.
