(A) The patient is in beach-chair position, right shoulder. Through the I portal, the coracoid process (black arrow), conjoint tendon (white arrow), and pectoralis minor are visualized. (B) With good visualization from the I portal (performed in front of the tip of the coracoid process), a disc pincer is introduced through the M portal (transpectoral medial portal) to extract the loose bodies located in the subcoracoid bursa, directing the pincer toward the lateral side to avoid injuring the plexus (asterisk). The black arrow indicates the coracoid process; white arrow, conjoint tendon.
