Which type of fracture involves the bone breaking but the skin remaining intact?

A fracture that involves the bone breaking while the skin remains intact is classified as a closed fracture. In this type of fracture, the broken bone does not protrude through the skin, which helps in reducing the risk of infection compared to open fractures where the skin is broken, exposing the bone and surrounding tissue.

Understanding the distinction between closed and open fractures is essential in first aid and medical treatment, as it dictates the immediate response and management needed. Closed fractures can typically be managed without the need for surgical intervention, while open fractures usually require more intensive treatment to prevent complications.

The other types of fractures mentioned do not accurately describe a scenario where the skin remains intact alongside a bone fracture. A complicated fracture may involve significant soft tissue damage or joint involvement, while a simple fracture can refer to a basic break in the bone that does not necessarily specify whether it is open or closed. Therefore, the classification of a closed fracture is a precise way to indicate that the fracture is contained within the body without external exposure.
