Question

Quizplus · Accepted Answer

The humerus should be positioned in external rotation for an inferosuperior axial projection of the shoulder joint. This helps to open up the joint space and improve visualization of the humeral head and glenoid cavity. Internal rotation or neutral rotation may cause the greater tubercle to overlap the humeral head and obscure the joint space. Therefore, only option 2 is correct.
