This video will demonstrate four projections of the wrist, PA, PA oblique, lateral, and ulnar deviation. 00:00:05

The patient will be seated at a 90 degree angle to the table. 00:00:14

The elbow will be flexed 90 degrees. 00:00:18

First projection will be the PA projection where we center the wrist to the image receptor. 00:00:22

Central ray is perpendicular to the mid-carpal. 00:00:31

We're going to have the patient flex the fingers to reduce OID, collimate to include proximal 00:00:34

half of metacarpals and distal one inch of the ulna and radius. 00:00:44

Left wrist, we'll place our left marker lateral to the extremity. 00:00:53

The next projection will be a PA oblique with lateral rotation and it's a 45 degree rotation. 00:01:02

The wrist is still centered at the mid-carpal, central ray perpendicular entering mid-carpal. 00:01:11

Collimation again will include proximal half of metacarpals and distal one inch of the 00:01:22

ulna and radius, left marker on the lateral aspect of the wrist. Next projection is going 00:01:27

to be a lateral projection of the wrist and it will be a lateral medial projection. Make 00:01:39

sure that the ulna and radius are superimposed. The thumb should be adducted. Central ray 00:01:48

is perpendicular to mid-carpal. Marker is placed anterior to the wrist. Again the 00:01:59

collimation includes proximal, half of the metacarpals, distal one inch of the 00:02:09

ulnar radius. The next projection, move the patient around, is going to be ulnar 00:02:16

deviation. So we'll place the palmar surface down. Then we're going to create as much angle 00:02:26

between the metacarpals and the ulna and radius as possible. Central ray is going to be perpendicular 00:02:39

to the scaphoid or navicular because we're trying to demonstrate the scaphoid without 00:02:48

self-superimposition. If the patient cannot deviate appropriately, we can angle the central 00:02:55

ray 10 to 15 degrees, proximally or distally, still entering the scaphoid or navicular. 00:03:06

Place your left marker on the image receptor. 00:03:27
