Anatomy coverage

Distal third of radius/ulna through proximal half of metacarpals.

Tech pearls

  • Slight finger flexion opens carpal interspaces.
  • Equal radius/ulna concavity = no rotation.

Image evaluation

  • Open carpal interspaces on PA
  • No rotation: equal concavity of radius and ulna
  • True lateral superimposes distal radius and ulna
  • Scaphoid elongated on ulnar deviation view

Common mistakes

Closed carpal spaces

Why: Fingers fully extended flattens the carpal arch.

Fix: Curl fingers slightly until the palm just lifts off the IR.

Rotation

Why: Elbow above shoulder level twists the forearm.

Fix: Drop the shoulder to table level — humerus, forearm and wrist in one plane.

Trauma modifications

  • If unable to pronate, image in position of comfort and add cross-table lateral.
  • Add Stecher / scaphoid views if FOOSH mechanism.
