What type of trauma occurs without penetration of the body?

Blunt trauma refers to injuries that occur from a forceful impact or collision without any penetration of the skin or body tissues. This type of trauma often results from incidents such as falls, collisions, or blows from objects, leading to internal injuries, bruising, or fractures while the outer skin remains intact.

In contrast, puncture trauma involves objects that penetrate the skin, creating an entry point into the body, which is not the case with blunt trauma. Penetrating trauma is characterized by wounds that break through the skin, allowing external objects to enter the body. Open trauma refers to injuries where the skin is broken, which again does not apply to blunt trauma. Thus, blunt trauma is defined by its lack of skin penetration and the nature of the forces involved.
