If a bone splinters at the site of impact and smaller bone fragments lie between the two main fragments, it is called

Options

A. compound fracture
B. impacted fracture
C. stress fracture
D. comminuted fracture

Answer

To answer the question, "If a bone splinters at the site of impact and smaller bone fragments lie between the two main fragments, it is called," we need to analyze the options provided and understand the definitions of different types of fractures.

### Step-by-Step Solution:

1. **Understanding the Question**: The question describes a scenario where a bone has splintered at the site of impact, and smaller bone fragments are present between the two main fragments. This indicates a specific type of fracture.

2. **Identifying the Options**:
- **Compound Fracture**: This type of fracture involves the bone breaking and piercing through the skin, but it does not specifically mention the presence of small fragments between the main pieces.
- **Impacted Fracture**: This occurs when one fragment of bone is driven into another, but again, it does not refer to the presence of smaller fragments.
- **Stress Fracture**: This is a small crack in the bone that occurs due to repetitive force or overuse, and it does not involve splintering or fragments.
- **Communicated Fracture**: This type of fracture involves the bone being broken into multiple pieces, with smaller fragments lying between the main fragments.

3. **Analyzing the Correct Option**: Given the definitions, the scenario described in the question aligns perfectly with a communicated fracture, where the bone is splintered, and smaller fragments are present at the site of impact.

4. **Conclusion**: Therefore, the correct answer to the question is **communicated fracture**.

### Final Answer:
The type of fracture described is called a **communicated fracture**.
