Case Discussion

Glenoid avulsion of the glenohumeral ligament (GAGL) is the avulsion of the inferior glenohumeral ligament (IGHL) from its glenoid insertion.

It can lead to traumatic anterior shoulder instability.

GAGL most often results from anterior shoulder dislocation due to forced hyperabduction and external rotation of the arm.
