Lateral movement of the hand toward the radius (thumb).

Lateral movement of the hand toward the radius (thumb).

• A. Ulnar deviation
• B. Pronation
• C. Radial deviation of the wrist
• D. Radius

Answer: (C)

Radial deviation of the wrist is the movement of the hand toward the thumb side. The radius is the forearm bone on that side, so moving toward it means moving laterally toward the thumb. Ulnar deviation would be toward the little finger side (ulna). Pronation is rotating the forearm to turn the palm down (or back). Radius is a bone, not a movement. So the described motion is radial deviation of the wrist.
