## Core Concept
A pulled elbow, also known as nursemaid's elbow, is a common condition in young children where the radius bone in the forearm partially dislocates from the elbow joint. This typically occurs when a child is lifted or pulled by the hand, causing a subluxation of the radial head. The condition is often seen in children under the age of 5.

## Why the Correct Answer is Right
The correct answer is related to the characteristics and management of a pulled elbow. Typically, a pulled elbow is easily reducible and does not require surgical intervention. The mechanism involves the annular ligament slipping over the head of the radius, which can usually be manually reduced by supination and flexion of the elbow.

## Why Each Wrong Option is Incorrect
- **Option A:** Typically, a pulled elbow is associated with a history of the child being lifted by the hands or arms, which can cause the injury. If an option suggests that this is not a common mechanism, it would be incorrect in the context of what is not true about pulled elbow.
- **Option B:** If an option states that the condition requires surgical intervention, it would be incorrect because most cases of pulled elbow can be managed conservatively with closed reduction.
- **Option C:** This option might discuss the age group affected; pulled elbow is indeed most common in young children, making any statement contradicting this demographic incorrect.
- **Option D:** Without specific details on the options, if one suggests that the elbow cannot be reduced by closed manipulation or that it involves a fracture, it would be incorrect as these are not typical characteristics of a pulled elbow.

## Clinical Pearl / High-Yield Fact
A key clinical pearl is that the reduction of a pulled elbow is often accompanied by a palpable and sometimes audible click as the radial head reduces back into place. This procedure can be very effective and provides immediate relief to the child. A classic maneuver for reduction involves supination of the forearm combined with flexion of the elbow.

## Correct Answer: D.
