"centring point1st metacarpophalangeal joint space."
"1st digit is positioned obliquely. Ideally the long axis of the thumb should run parallel to the image receptor. There should be no foreshortening of the phalanges, the joint spaces should not be completely open."
"It is best not to overthink this projection, think of it as PA hand with some slight ulnar deviation and a tight collimation over the thumb. It's best to do dedicated thumb views when there is thumb pathology suspected, centring at the hand cause problems with beam divergence."
"This projection will demonstrate the thumb in its natural 'AP' position, it is the thumb radiograph you would observe on an AP hand radiograph. It is a great projection to assess the thumb for the base of thumb fractures."
