Abstract

Glenoid avulsion of the glenohumeral ligament (GAGL) is a traumatic cause of shoulder instability. GAGL lesions are a rare shoulder pathology most commonly reported as a source of anterior shoulder instability, with no current reports implicating this pathology as a cause of posterior instability. Satisfactory surgical repairs of GAGL lesions with anterior shoulder instability have been well documented; however, this Technical Note highlights the successful repair of a posterior GAGL lesion through a single working portal with suture anchor fixation of the posterior capsule.
