FILM WRIST + FOREARM projections/positions

projection/position?

extra: SID? field? grid? kVp? CR? collimation?

PA projection of right wrist

SID = 40in, field = 8×10 portrait, NONgrid, kVp = 55-65

CR is perpendicular to IR + directed to the midcarpal area

when collimating, want to see mid+proximal metacarpals, carpals, distal radius + ulna

projection/position?

extra: angle degree? SID? field? grid? kVp? CR? collimation?

PA projection oblique position (lateral rotation)

SID = 40in, field = 8×10 portrait, NONgrid, kVp = 60-70, 45° lateral rotation

CR perpendicular to IR + directed to midcarpal area

when collimating, want to see mid+proximal metacarpals, carpals, distal radius + ulna

projection/position?

extra: SID? field? grid? kVp? CR? collimation?

lateromedial projection of left wrist (lateral = THUMB up)

SID = 40in, field = 8×10 portrait, NONgrid, kVp = 60-70

CR is perpendicular to IR + directed to midcarpal area

when collimating, want to see mid+proximal metacarpals, carpals, distal radius + ulna

projection/position?

extra: SID? field? grid? kVp? CR? collimation?

PA axial scaphoid projection, with ulnar deviation position

SID = 40in, field = 8×10 portrait, NONgrid, kVp = 55-65

ulnar deviation pointing hand towards ulna side = pinky side

CR is angled 10-15° proximally toward elbow + centered to scaphoid (which is ¾ in (2cm) distal + medial to radial styloid process)

when collimating, you want distal radius + ulna, carpals and proximal metacarpals [want scaphoid demonstrates clearly]

projection/position?

extra: SID? field? grid? kVp? CR? collimation?

PA scaphoid hand-elevated and ulnar deviation of wrist

SID = 40in, field = 8×10 portrait, NONgrid, kVp = 55-65

place hand + wrist elevated on 20° angle sponge

CR is perpendicular to IR + directed to scaphoid [CR is NOT angled since sponge angels for us]

when collimating, you want distal radius + ulna, carpals and proximal metacarpals [want scaphoid demonstrate clearly]

projection/position?

extra: angle degree? SID? field? grid? kVp? CR? collimation?

carpal canal - tangential, inferosuperior projection of the wrist

ALSO known as the Gaynor Hart method

SID = 40in, field = 8×10 portrait, NONgrid, kVp = 55-65

rotate hand+wrist 10° internally (toward radial side, thumb)

CR is angled 25-30° proximally + direct it to 1 INCH distal to base of 3rd metacarpal (so the center of palm of hand)

when collimating, you want carpals + midmetacarpals

projection/position?

extra: SID? field? grid? kVp? CR? collimation?

AP projection of right forearm

SID = 40in, field = 14×17in portrait, NONgrid, kVp = 65-75

CR is perpendicular to IR + directed to midforearm

collimate need minimum of 1-1 ½ INCH distal to wrist and elbow joints

when collimating, want to see entire radius + ulna, minimum of proximal row carpals, distal humerus w pertinent sodt tissues (fat pads/stripes)

extra: SID? field? grid? kVp? CR? collimation?

lateromedial projection of (right) forearm

SID = 40in, field = 14×17in portrait, NONgrid, kVp = 65-75

CR is perpendicular to IR + directed to midforearm

collimate need minimum of 1-1 ½ INCH distal to wrist and elbow joints

when collimating, want to see entire radius + ulna, minimum of proximal row carpals, distal humerus w pertinent sodt tissues (fat pads/stripes)
