When a bone breaks into more than two pieces, such a fracture is called

Options

A. simple fracture
B. Green stick fracture
C. Comminuted fracture
D. Compound fracture

Answer

To answer the question, "When a bone breaks into more than two pieces, such a fracture is called," we will analyze the options provided and determine the correct answer step by step.

### Step 1: Understand the Types of Fractures
We have four options to consider:
1. **Simple Fracture**: This type of fracture involves a bone breaking either partially or completely, but without any injury to the surrounding tissue.
2. **Greenstick Fracture**: This type occurs primarily in children, where the bone bends and partially breaks, resembling the way a green twig bends and breaks.
3. **Comminuted Fracture**: This type of fracture occurs when the bone breaks into more than two pieces. It is characterized by multiple fragments of bone.
4. **Compound Fracture**: This fracture is when the bone breaks completely and protrudes through the skin, often causing damage to surrounding tissues and bleeding.

### Step 2: Identify the Correct Definition
The question specifically asks for a fracture where the bone breaks into more than two pieces.
- The **Comminuted Fracture** is defined as a fracture where the bone breaks into multiple fragments, which fits the description given in the question.

### Step 3: Eliminate Incorrect Options
- **Simple Fracture** does not involve multiple pieces.
- **Greenstick Fracture** involves bending and partial breaking, not multiple pieces.
- **Compound Fracture** involves complete breaking but does not specify multiple fragments.

### Conclusion
Based on the definitions and the analysis of the options, the correct answer to the question is:
**Comminuted Fracture**.

### Final Answer
When a bone breaks into more than two pieces, such a fracture is called a **Comminuted Fracture**.
