A simple crack in the bone when the two parts of the bone remain together is called
(a) Green stick fracture
(b) Simple fracture
(c) Comminuted fracture
(d) Compound fracture

Options

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

Answer

To solve the question about the type of fracture described, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the name of a fracture where there is a simple crack in the bone but the two parts remain together.

2. **Evaluate the Options**:
- **Option (a) Green stick fracture**: This type of fracture occurs when there is a crack in the bone but the bone remains intact. It is often seen in children whose bones are more flexible.
- **Option (b) Simple fracture**: In a simple fracture, there is a break in the bone, but the skin remains intact. This does not fit the description since it involves breakage.
- **Option (c) Comminuted fracture**: This type involves multiple fragments of the bone being broken. Since the question specifies no breakage, this option is incorrect.
- **Option (d) Compound fracture**: A compound fracture involves a break in the bone that pierces through the skin. This does not match the description provided in the question.

3. **Identify the Correct Answer**: Based on the evaluations:
- The only option that describes a simple crack in the bone where the two parts remain together is **Option (a) Green stick fracture**.

4. **Conclusion**: Therefore, the correct answer to the question is (a) Green stick fracture.
