Type I represents a frayed or degenerative labrum with attachment of the labrum to the glenoid. Type II represents detachment of the superior labrum and biceps from the glenoid rim. Type III represents a bucket-handle tear of the labrum with an intact biceps anchor. Finally, type IV represents a bucket handle tear of the labrum that extends into the biceps tendon.
