"articulation between the distal radius and the ulna is open or has little superimposition."
"The scaphoid posteroanterior axial view is part of a four view series of the scaphoid, wrist and surrounding carpal bones. This view is a complementary projection to the PA view."

"The scaphoid does not sit 100% flush with the image receptor when the hand is resting (see Figure 1), the scaphoid has a natural palmar tilt, therefore angling to that tilt will result in a 'truer' PA radiograph."
"Ulnar deviation is necessary as it moves the scaphoid away from the radius and rotates it in the palmer aspect, minimising superimposition and achieving a pure PA projection 1-3. However, patients with a fractured scaphoid will be in a lot of pain so deviating their hand to the ulna can be quite a task; only deviate the hand as much as the patient can bear it."

"The scaphoid posteroanterior axial view is part of a four view series of the scaphoid, wrist and surrounding carpal bones. This view is a complementary projection to the PA view."
"This view aims to show the scaphoid in its true anatomical appearance without any superimposition or foreshortening. As the scaphoid sits in a slight volar tilt, the angle of the axial view ensures there is no superimposition hence allowing the visualisation of any subtle distal, middle or proximal fractures 1 of the scaphoid."
