What is a wound?
A wound interrupts skin continuity and integrity. It may be the result of trauma, both minor or severe, or of a pathological process. Wounds can be classified as a function of the level of damage to the different layers of the skin. The healing prognosis can be very different depending on the depth and mechanism of the lesions.
There are two types of wounds:
Pure epidermal lesion (read more...)
This is a small scratch or a scrape that will not bleed.
Heals with no residual scarring.
Superficial dermal-epidermal wound (read more...)
Abrasion to the tops of the dermal-epidermal junction, which will cause bleeding at isolated spots (Skin abrasion / Skin graft donor site / superficial 2nd degree burn).
Deep dermal-epidermal wound (read more...)
Deep dermal wound with complete rupture of the dermal-epidermal junction (deep 2nd degree burn / Surgery).
Healing will always leave superficial scarring.
Deep wound (read more...)
A deep wound affecting the full thickness of the skin and which may damage the fat cell tissue or the underlying muscle layer.
Healing will always leave a scar.
