Hagl and reverse hagl lesions

Abstract

Tearing of the anteroinferior glenoid labrum (Bankart lesion) and of the posteroinferior glenoid labrum (reverse Bankart lesion) are well-documented, common injuries following traumatic shoulder subluxation or dislocation. The labral injury, as well as the loss of tension of the attached capsuloligamentous structures, is known to lead to recurrent instability. Injuries to the capsuloligamentous attachments to the humerus are much less common but have recently gained attention due to advancements in arthroscopic experience and imaging techniques. In 1942, Nicola first described an acute shoulder dislocation with avulsion of the anterior band of the inferior glenohumeral ligament (IGHL).
