Rad-104 Wrist Procedures

PA wrist position

upper arm resting on table in same plane

elbow flexed 90-degrees

wrist in center of IR

slight curling of digits

PA wrist CR

perpendicular to midcarpal area

PA wrist collimation

includes proximal half of metacarpals to distal portion of radius and ulna

PA wrist criteria

no rotation in carpals, metacarpals, or radius

no excessive flexion of digits

• no digit overlap with metacarpals

demonstrated distal radius-ulna, carpals, proximal half of metacarpals

adequate density and contrast

lateral wrist positioning

rest upper arm on table

elbow flexed 90-degrees

forearm and wrist resting on medial surface

radial and ulnar styloid superimposed and perpendicular to IR

lateral wrist CR

perpendicular to wrist joint

lateral wrist collimation

includes proximal half of metacarpals to distal portion of radius-ulna

lateral wrist criteria

superimposed radius and ulna, carpals, and proximal half of metacarpals

demonstrated distal radius and ulna, carpals, proximal half of metacarpals

adequate density and contrast

PA oblique wrist positioning

upper limb positioned as described for previous wrist projections

45 degree rotation from IR

support with wedge sponge

PA oblique wrist CR

perpendicular to midcarpal area

distal to radius

PA oblique wrist collimation

includes proximal half of metacarpals to distal radius-ulna

PA oblique wrist criteria

adequate obliquity

• slight interosseus spaces between third-to-fourth and fourth-to-fifth metacarpal shaft

• slight overlap of radius-ulna

demonstrated scaphoid and trapezium

demonstrated distal radius-ulna, carpals, proximal half of metacarpals

adequate density and contrast

PA axial scaphoid positioning

upper limb resting on table w/axilla in contact to place limb on same plane

wrist in center of IR

support with sponge

PA axial scaphoid CR

perpendicular to table entering at scaphoid

angled 20 degrees towards elbow

PA axial scaphoid collimation

includes proximal half of metacarpals to distal radius-ulna

PA axial scaphoid criteria

scaphoid without self-superimposition

no rotation in carpal, metacarpals, or radius

demonstrated distal radius and ulna, carpals, and proximal half of metacarpals

adequate density and contrast
