Criteria :
Anatomy Demonstrated:
• PA projection of entire hand and wrist and about 2.5 cm (1 inch) of distal forearm are visible. • PA projection of hand demonstrates oblique view of the thumb.
Position:
• Long axis of hand and wrist aligned with long axis of IR.
• No rotation of hand, as evidenced by symmetric appearance of both sides or concavities of shafts of metacarpals and phalanges of digits 2 through 5 and the appearance of equal amounts of soft tissue on each side of phalanges 2 through 5.
• Digits should be separated slightly with soft tissues not overlapping.
