In the context of head trauma, which fracture type can be caused by external compression forces?

In the context of head trauma, a compression fracture occurs when external forces compress the bone, leading to a reduction in its height or thickness. This type of fracture is particularly relevant in situations where significant force is applied to the skull, such as during a fall or blunt force trauma. The unique nature of the compression fracture allows for the bone to crumple or deform under pressure without necessarily breaking into separate pieces, which is crucial in understanding the mechanics of head injuries.

In contrast, a comminuted fracture involves the bone being shattered into several pieces, which typically requires more force and does not primarily result from direct compression. A simple fracture refers to a clean break where the bone remains aligned and does not penetrate the skin, while a compound fracture typically involves the bone breaking through the skin. Both of these fracture types do not specifically arise from compression forces, focusing instead on their connectivity and exposure to external environment.
