OBLIUQE WRIST

Pathology Demonstrated : 

Fx of distal radius and ulna, Isolated fx of radial or ulnar styloid processes , arthirts

IR Size :

18*24

IR Position :

Crosswise / tabletop

Sheilding :

Place lead shield over pt’s lap

Pateint Position : 

Set pt at end table , with both hands extended and pronated on IR 

Part Position : 

Hand , wrist align and center long axis of IR 

From pronated position,rotate wrist and hand laterally 45°. 

For stabillety, place a 45° support under thumb side of hand , or partially flex fingers to arch hand so that figertips rest slightly on cassette 

CR : 

Direct midcarpal area

Collimation : 

Collimate to wrist on 4 sides ; include distal raduis and ulna an MC area . 

Criteria : 

Structure shown: distal radius , ulna ,carpals , and at least to midmetacarpal area . The trapezium and scaphoid should be well visualized. Other carpals slightly superimpostions 

Position: long axis of the hand , wrist , forearm should be aligned with IR 

True —> wrist should be evident by ulnar head being paritally superimposed by distal radius 

2- proximal third ,fourth,fifth metacarpals should appear mostly superimposed.
