Question

Quizplus · Accepted Answer

The lateral forearm projection with proximal humerus elevation and wrist internal rotation is known as the Coyle method. In this projection, the capitulum is distal to the medial trochlea (option 3), and the radial head is posterior to the coronoid process (option 1). Pisiform bone is not visible in this projection as it is in the volar aspect of the wrist. Therefore, option 2 is incorrect. Option 4, stating the Pisiform bone is distal to the distal scaphoid is anatomically incorrect.
