A Bankart lesion is an injury involving the glenoid labrum of the shoulder. Its cause is an anterior shoulder dislocation.1 It is named after a British orthopedic surgeon, Arthur Sydney Blundell Bankart.2 A Bankart lesion is often accompanied by a Hill-Sachs lesion, which is a cortical depression on the posterolateral head of the humerus.
Bankart lesions result from the detachment of the anterior inferior labrum from the underlying glenoid.2 There are two common forms of bankart lesions, the bony Bankart and the soft Bankart. A bony Bankart lesion is a form of a Bankart lesion wherein there is a fracture of the anterior-inferior glenoid cavity of the scapula bone.3 While the bony Bankart involves the bony margin the soft Bankart lesion involves the labral only.2
