What defines a compound fracture?

• A. Fracture of the radius
• B. Fracture from repetitive use
• C. Fracture with a broken bone protruding through the skin
• D. Fracture with the bone splintered into many pieces

Answer: (C)

A compound fracture is characterized by a broken bone that penetrates through the skin, making it an open fracture. This type of fracture poses a greater risk for infection due to the exposure of bone and internal tissues to the external environment. The presence of a wound at the fracture site is what distinguishes a compound fracture from a simple, or closed fracture, where the skin remains intact. Understanding this definition is crucial as it highlights the severity and treatment considerations associated with compound fractures.

In contrast, the other options describe different types of fractures or conditions. A fracture of the radius pertains to a specific bone, rather than the nature of the fracture itself. A fracture from repetitive use refers to a stress fracture, which occurs due to overuse and is typically a small crack rather than a break that protrudes through the skin. Lastly, a fracture where the bone is splintered into many pieces is classified as a comminuted fracture, which again is distinct in its characteristics. Recognizing these distinctions is important for understanding fracture types and their implications for treatment and recovery.
