Which of the following statements is true regarding fractures?

The statement that not all fractures involve skin rupture is accurate. Fractures can be classified as either open or closed, depending on whether the bone breaks through the skin. An open fracture, also known as a compound fracture, does indeed involve the skin being ruptured, which can expose the bone and lead to a higher risk of infection. In contrast, a closed fracture does not break the skin and generally poses a lower risk of complications. Therefore, it's essential to understand that many fractures occur without any disruption to the skin, making this statement true.

The other options present misconceptions about fractures. For instance, not every fracture requires surgical intervention; many can be treated conservatively with immobilization and rest. The idea that all fractures heal quickly without treatment isn't accurate either, as healing time depends on the fracture type and treatment. Lastly, while fractures are common in adults, they can also occur in children, often due to different causes such as sports injuries or falls, illustrating that they are not exclusive to one age group.
