For an oblique position, rotate the hand

• A. 15
• B. 30
• C. 45
• D. 60

Answer: (C)

An oblique hand view is achieved by rotating the hand diagonally relative to the imaging plane to reduce overlap of the bones and reveal structures that sit in between. About 45 degrees provides the best balance: it sufficiently separates the carpal bones and metacarpals so you can see joints and spaces clearly, while avoiding excessive distortion that can come from turning the hand more than that. If you rotate only 15 or 30 degrees, there’s still too much superimposition; at around 60 degrees you risk losing normal relationships and introducing distortion. So 45 degrees is the standard angle that gives a clear, useful oblique view.
