**Core Concept**
Pauwel’s angle is a radiographic measurement in pediatric femoral neck fractures, defined as the angle between the femoral neck and the shaft on a radiograph. It reflects the degree of femoral neck angulation and is a key predictor of fracture stability and outcome.

**Why the Correct Answer is Right**
An increase in Pauwel’s angle (>30°) indicates a more vertical femoral neck, which correlates with increased risk of displacement due to the reduced stability of the fracture site. This occurs because a steep angle reduces the mechanical resistance of the femoral head to displacement forces. Higher Pauwel’s angles are associated with greater likelihood of malalignment and complications, especially in children with open growth plates.

**Why Each Wrong Option is Incorrect**
Option A: A higher Pauwel’s angle does not indicate a good prognosis; rather, it is linked to worse outcomes due to instability and increased displacement risk.
Option B: Impaction refers to the compression of bone fragments, which is not directly related to Pauwel’s angle. This is a misinterpretation of fracture mechanics.
Option D: While trabecular alignment can be affected, Pauwel’s angle is not a direct measure of trabecular displacement; it reflects mechanical angulation, not microarchitectural changes.

**Clinical Pearl / High-Yield Fact**
In pediatric femoral neck fractures, Pauwel’s angle >30° is a strong predictor of displacement and poor healing — remember: **"Higher angle = higher displacement risk."**

✓ Correct Answer: C. More chances of displacement
