Which type of fracture results from fragments being pushed into each other?

An impacted fracture occurs when the ends of a fractured bone are driven into each other, leading to a mechanism where one fragment is forcibly driven into the other. This type of fracture often occurs during falls or in high-impact accidents, where significant force causes one bone fragment to compress into another.

In the context of fracture types, the other options represent different mechanisms:

• Spiral fractures occur when a twisting or rotational force is applied to a bone, resulting in a helical break.

• Comminuted fractures involve the bone breaking into several pieces due to high-energy trauma, but this does not specifically describe the interlocking of fragments seen in impacted fractures.

• Transverse fractures result from a bending force, leading to a straight break across the bone.

Each of these types has distinct characteristics based on the force applied and the resulting fracture pattern, but for the scenario described, where fragments are pushed into each other, the impacted fracture is the correct classification.
