+/- fracture at the anteroinferior aspect of the glenoid.glenoid labrum is not commonly visualized by CT, although CT arthrography may demonstrate labral avulsion 4.+/- fracture of the anteroinferior aspect of the glenoid 4.glenolabral articular disruption (GLAD): associated anteroinferior articular cartilage and labral injury.anterior labroligamentous periosteal sleeve avulsion (ALPSA): mobilized labrum remains attached to the glenoid periosteum.Perthes lesion of the shoulder: chondrolabral detachment with periosteal stripping of the scapula with the labral fragment attached to the periosteum without significant displacement 2.

Bankart and Hill-Sachs defects are 11x more likely to occur together than isolated injuries 5. The same mechanism of compression can result in a Hill-Sachs defect. 'Soft' Bankart lesions are more common than 'bony' Bankart lesions 5. There is detachment of the anteroinferior labrum from the underlying glenoid, and the labral tear may extend further superiorly or posteriorly. Impaction fracture of the anteroinferior glenoid margin commonly co-occurs. Bankart lesions occur as a direct result of anterior dislocation of the humeral head, whereby the humerus is compressed against the labrum.
