What is penetrating injury?
Penetrating trauma is an open wound injury caused by an object piercing the skin and entering a body tissue, resulting in a deep but relatively narrow entry wound. A blunt or non-penetrating trauma, on the other hand, may cause some deep damage, but the overlying skin is not necessarily broken, and the wound remains closed to the outside environment. The penetrating object may remain in the tissues, return through the same path it entered, or pass through the entire thickness of the tissues and exit from another location.
