  • Hand and wrist in lateral position, thumb up
Critique

Positioning
  • The wrist in a lateral position demonstrated by:
    • Super-imposition of distal end of scaphoid and pisiform
    • Super-imposition of the radius and ulna
  • Long axis of first metacarpal is aligned parallel with forearm
  • Ulna styloid in profile posteriorly
  • Trapezium with no super-imposition of first metacarpal
Area Covered
  • Distal radius and ulna, carpals, mid metacarpal area
Collimation
  • Centre: Mid-carpal area
  • Shutter A: Half the metacarpals to one quarter of distal radius and ulna
  • Shutter B: Skin margin
Exposure
  • Bony trabecular patterns and cortical outlines are sharply defined
  • Soft tissues are visualised
  • Sufficient contrast and density to demonstrate posterior fat stripe
