Which statement best describes a comminuted fracture?

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

Answer: (A)

A comminuted fracture occurs when a bone is broken into multiple pieces, typically three or more, with fragments that may be crushed. The statement describes this fragmentation into small pieces, which is the hallmark of a comminuted fracture. In contrast, simply having multiple fracture lines in one bone isn’t necessarily fragmentation within a single event. An incomplete fracture means the bone is not fully broken through (like a greenstick), and an open fracture involves the skin being breached, which is about soft-tissue injury rather than fragmentation. Comminuted fractures are often the result of high-energy trauma and may require surgical fixation to realign all the fragments.
