A 17-year-old basketball player presents to your office with persistent shoulder soreness following a fall during a game 2 months ago. Immediately following this incident, a teammate manipulated the shoulder, which resolved his pain and allowed him to finish the game. His current radiograph is shown in Figure A.

Long head of the biceps tear
Superior labrum anterior to posterior tear
Anteroinferior labral tear
Which patient would be ideal for an open shoulder reduction and glenoid bone augmentation?

An athlete has recurrent anterior shoulder instability despite non-operative treatment including PT and bracing. He is noted to have anterior glenoid bone loss and a coracoid transfer (Latarjet) procedure is recommended. This is believed to improve stability through which of the following mechanism(s)?

Answers 1, 2 and 5 are correct.
Both 1 and 2 are correct.
