MR arthrography of the glenohumeral joint.

This article explores MR arthrography of the glenohumeral joint, including normal anatomy of the glenoid labrum, glenohumeral ligaments, and biceps labral complex. Examples of glenohumeral joint instability include the Bankart lesion, anterior labroligamentous periosteal sleeve avulsion, glenolabral articular disruption, humeral avulsion of the glenohumeral ligament, and Bennet lesion. Normal variations include the sublabral foramen, the Buford complex, and cord-like middle glenohumeral ligament. Labral tears and paralabral cysts are also discussed.
