**Core Concept**
Children's bones are more flexible and have growth plates, making them prone to specific types of fractures. These fractures are often a result of the unique anatomy and physiology of growing bones.

**Why the Correct Answer is Right**
The correct answer is a fracture that is uncommon in children due to their bone structure. Children's bones are more prone to fractures that occur at the growth plates, such as physeal fractures, or fractures that involve the metaphysis, like greenstick fractures. However, certain types of fractures are less common in children due to their bone density and growth patterns.

**Why Each Wrong Option is Incorrect**
**Option A:** This type of fracture is actually common in children due to their bone structure and growth patterns.
**Option B:** This fracture type is also common in children, especially in those with open growth plates.
**Option C:** This fracture is more commonly seen in adults, particularly in the elderly population with osteoporosis.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that children's fractures often involve the growth plates, and their bones are more prone to greenstick fractures due to their flexibility.

**Correct Answer: D.**
