For the latter, there are also two methods to express the defect size: Bankart lesion Bankart lesions are labral tears without an osseus fragment.
Glenohumeral stability from concavity-compression: In Bankart repairs, the labral fragment is sutured back to the glenoid rim using suture anchors. They are frequently seen in association with a Hill-Sachs lesion.
