For the AP oblique projection (Grashey method) of the shoulder, the patient is rotated: 35Â° to 45Â° toward the affected side For the scapular Y projection in the anterior oblique position, the patient is rotated:
Abduction of the arm is also called abduction of/at the shoulder. This motion actually can be divided into two motions: true abduction of the arm at the shoulder and upward rotation of the scapula. Muscles: supraspinatus (initiates abduction - first 15 degrees), deltoid (up to 90 degrees), trapezius and serratus anterior (scapular rotation, for abduction beyond 90 degrees). The deltoid muscle abducts the arm, but at 90 degrees the humerus bumps into the acromion. Beyond this point, further abduction is the result of upward scapular rotation.
