What is 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 is characterized by the bone being broken or crushed into several small pieces. This type of fracture typically results from high-impact trauma, such as a severe fall or car accident. The nature of the injury causes the bone to shatter, leading to multiple fragments rather than a clean break.

Understanding the distinction between this and other types of fractures is key in medical contexts. For example, while multiple fractures of the same bone may involve a more complex situation, a comminuted fracture specifically implies the crush of bone material into pieces – a critical aspect that affects treatment and healing processes. An incomplete fracture refers to a bone that has not fully broken through, which is different from the complete shattering of a comminuted fracture. Lastly, a fracture that breaks the skin describes an open fracture, which is again different from the internal fragmentation seen in comminuted fractures. By grasping these distinctions, one can better appreciate the severity and implications of different fracture types in medical diagnosis and treatment.
