Which of the following is classified as a major injury?

A bone fracture is classified as a major injury due to the significant impact it can have on a person's health and mobility. Fractures often require medical intervention such as casting or surgery, and they can lead to complications if not properly treated. The severity of a fracture can range from simple hairline fractures to complex breaks that may damage surrounding tissues or lead to further injury.

In contrast, minor cuts, bruising, and fatigue generally do not result in the same level of immediate risk to a person's health or require intensive medical treatment. While these conditions can certainly be painful or uncomfortable, they typically involve less severe physical trauma than a fracture, which can immobilize a person and necessitate a longer recovery period. Therefore, classifying a bone fracture as a major injury reflects its potential for long-term implications on a person’s functionality and overall health.
