MR arthrography of the shoulder
In the 6-9 o'clock position, there is a tear between the posterior glenoid labrum and glenoid articular cartilage without labral dislocation.
No Hill-Sachs injury can be detected.
The rotator cuff tendons are normal.
Tears of the labrum can develop after acute trauma or repetitive microtrauma. In the cumulative microtrauma model, a Kim lesion may develop. This is thought to occur with cumulative rim loading secondary to persistent shoulder subluxation or microtrauma. This pathologic process leads to a loss of chondrolabral containment, with subsequent development of posterior labral marginal cracks and undermining of the labrum or partial avulsions of the glenoid labrum.
