The best description for a comminuted fracture is:

• A. Multiple fractures of the bone.
• B. An incomplete fracture.
• C. A bone that is broken or crushed into small pieces.
• D. A bone that breaks the skin.

Answer: (C)

A comminuted fracture is defined by the bone being broken into multiple fragments. This fragmentation is the hallmark, distinguishing it from a simple break into two pieces or from an incomplete fracture where the bone isn’t broken all the way through. The multiple small pieces often result from high-energy trauma and make alignment and healing more complex. On imaging, you’d expect several fracture lines with several fragments rather than a single clean break. While open fractures involve the skin breaking, comminution specifically describes the fragmentation of the bone itself, which can occur with or without the skin being involved.
