A torus fracture is the result of what kind of force?

1. Shearing

2. Traction

3. Compression

4. Twisting

The correct answer is: Compression

A torus fracture, also known as a buckle fracture, commonly occurs in the context of pediatric injuries where the bones are softer and more pliable. This type of fracture arises primarily from compression forces, which result in a bowing or buckling effect in the bone rather than a complete break. The mechanism involves the application of a compressive force that produces localized deformation but does not extend completely through the bone, leading to this characteristic fracture pattern. In contrast, shearing forces involve a sliding motion that can cause fractures in different patterns, traction forces pull tendons or ligaments from the bone, and twisting forces can lead to spiral fractures. Thus, these types of forces are not typically associated with the formation of a torus fracture, making compression the correct and most fitting answer.
