What tear was identified on the MRI of the right shoulder?

Explanation:
The key idea is identifying a soft-tissue tear of the shoulder structure and whether it is displaced. The described MRI finding points to a posterior labral tear that is detached from the glenoid rim but remains in its normal position (nondisplaced). This means the labrum has separated from the rim, creating a tear, but the fragment hasn’t shifted into the joint space or away from the rim—hence nondisplaced. This matches a posterior labral injury, which is different from a full-thickness rotator cuff tear that would involve the rotator cuff tendon itself and show complete tendon disruption, or a biceps tendon tear, which would involve the biceps tendon. An AC joint separation would show widening or ligament disruption at the acromioclavicular joint, not a labral detachment.
