What position of the shoulder and proximal humerus best projects the lesser tubercle in profile medially?

Internal rotation
External rotation
Exaggerated rotation
Neutral rotation

The correct answer is: Internal rotation

To visualize the lesser tubercle in profile medially, internal rotation of the shoulder is the most effective position. When the arm is internally rotated, the humerus is positioned so that the lesser tubercle faces directly anteriorly, allowing it to project clearly in profile. This contrasts with the other positions: - In external rotation, the greater tubercle is highlighted instead, causing the lesser tubercle to be less visible and not in profile. - Exaggerated internal or external rotation positions can distort the alignment of the humerus further, making it less favorable for a clear view of the lesser tubercle. - With the arm in a neutral position, neither the lesser tubercle nor the greater tubercle is prominently displayed as they are not optimally positioned for a true lateral view. Thus, the internal rotation position is specifically designed to achieve this clear and focused view of the lesser tubercle, making it the correct choice in this scenario.
