Which type of fracture results from the bone being splintered into many pieces?

• A. Greenstick fracture
• B. Simple fracture
• C. Comminuted fracture
• D. Compound fracture

Answer: (C)

A comminuted fracture is characterized by the bone being broken into multiple fragments or pieces. This type of fracture typically results from a high-impact force or trauma, which causes the bone to shatter rather than break cleanly. It is particularly severe and can complicate the healing process due to the multiple fragments that need to be aligned and stabilized.

In contrast, a greenstick fracture involves an incomplete fracture of a bone, commonly seen in children, where one side of the bone bends while the other side breaks. A simple fracture, also known as a closed fracture, refers to a clean break that does not break the skin, making it less complicated than a comminuted fracture. A compound fracture, on the other hand, is one where the bone breaks through the skin, posing significant risks for infection and requiring immediate medical attention. Overall, the defining characteristic of a comminuted fracture is the fragmentation of the bone, which is why it is the correct choice.
