What tube tilt is required for the internal rotation of the shoulder?

For the internal rotation of the shoulder, no tube tilt is required because the positioning of the shoulder allows for proper visualization of the structures without angling the tube. When performing an internal rotation view, the patient's arm is placed in a way that the humerus is aligned with the image receptor and the shoulder joint is centered. This positioning maximizes the natural angle of the shoulder and captures the anatomy without the need for additional tilt.

In imaging practices, unnecessary tube tilt can distort the images and obscure essential anatomical details. Therefore, maintaining the tube in a horizontal position helps ensure that the captured images of the shoulder are clear and accurately represent the anatomical relationships.
