Any scaphoid view requires the scaphoid to be in Ulnar Deviation. What is the purpose of Ulnar Deviation?
Scaphoid without superimposition and foreshortening
The Stetcher:
Elevate the part 20 degrees
Or

Acromion Process
How do you properly position for an AP scapula?
The patient supine, the arm is abducted at a right angle with the chest, elbow is flexed with the hand brought to the forehead, CR is directed perpendicular 5 cm inferior to the coracoid process, quiet breathing
For an AP Axial Clavicle the degree of angulation is:
