Final answer:
With blunt force trauma, the injury spreads over a wide area, meaning the skin typically remains unbroken, unlike injuries from sharp objects that pierce or cut the skin.
Step-by-step explanation:
With blunt force trauma, the force of the injury occurs over a broad area, and the skin is usually not broken. This kind of injury can contrast with injuries from sharp objects, which concentrate the same force on a smaller area, such as the sharp end of a needle, and are much more likely to break the skin. Examples of blunt force trauma could include being hit by a large object like a ball or falling against a broad surface.
It can be associated with different types of injuries internally, such as bruises, fractures, or internal organ damage. However, the skin may remain intact, depending on the nature and force of the impact. It's also useful to differentiate between various types of fractures in these contexts, like puncture fractures where the bone breaks through the skin, and how they may arise from different causal forces.
