Wrist xrays are done not only for trauma but also for other wrist pathologies. Following wrist xrays are generally done in afflictions of wrist.
Some of these xrays are routinely done whereas others have their special indication.
Also known as palmar dorsal view, this view demonstrates the carpal joint spaces more clearly and is quite helpful in evaluating a scapholunate dissociation.
Antreoposterior view is taken by placing the dorsum of the hand over xray filmm cassette and the palm faces towards the xray machine tube. The xray beam passes from palmar to dorsal. [In PA film, palmar surface lies flat on film & x-ray beam passes from the dorsal to palmar surface]
PA view: Ulnar styloid is peripheral.
AP View: Ulnar styloid points centrally.
PA View with Ulnar side of the hand elevated 20°
This view is helpful in better demonstrating the articular surfaces between the scaphoid and lunate because the articular surfaces are parallel to the central ray in this projection.
45 Degree Oblique view in Pronation.
The hand and forearm are positioned on a 45° wedge of foam rubber
This view is helpful primarily for imaging the dorsal aspect of the triquetrum, the radiopalmar part of the scaphoid, and the hamate.
It also helps in evaluation of the radial styloid and the articulations between the scaphoid & trapezium and trapezium & trapezoid.
35 Degree Oblique View in Supination
The ulnar edge of the hand rests on the film cassette. For visualizing the pisiform and the articulation between the pisiform and triquetrum.
Ulnar and Radial Deviation Views
Changes in the width of the intercarpal joint spaces may occur because of increased intercarpal mobility and the findings are better demonstrated in these views. In short these views can provide information on the integrity of the carpal ligament system.
Flexion and Extension Views
Clenched Fist PA views
Useful additional view for evaluating suspected intercarpal ligament damage. Widening of the joint space (>2 mm) is considered significant.
