Which type of fracture is defined as bone broken into multiple pieces?

• A. Comminuted Fracture
• B. Greenstick Fracture
• C. Impacted Fracture
• D. Spiral Fracture

Answer: (A)

When a bone breaks into multiple pieces, that pattern is called a comminuted fracture. The defining feature is fragmentation into several bone fragments at the fracture site, which can complicate alignment and healing because there are more pieces to manage.

Greenstick fracture describes an incomplete crack, usually in children, where the bone bends and cracks on one side but doesn't break into separate pieces. An impacted fracture involves one fragment driven into another, causing compression rather than separate fragments. A spiral fracture results from a twisting mechanism and forms a spiraling break line around the bone, not necessarily characterized by multiple fragments.
