Pressure ulcers are full-thickness wounds that extend into the dermis and heal by scar formation because the deeper structures do not regenerate,hence the need for full-thickness repair.The full-thickness repair has three phases: inflammatory,proliferative,and remodeling.A wound heals by primary intention when wounds such as surgical wounds have little tissue loss; the skin edges are approximated or closed,and the risk for infection is low.Partial-thickness repairs are done on partial-thickness wounds that are shallow,involving loss of the epidermis and maybe partial loss of the dermis.These wounds heal by regeneration because the epidermis regenerates.Tertiary intention is seen when a wound is left open for several days,and then the wound edges approximated.Wound closure is delayed until risk of infection is resolved.
