Optimal treatment for patients with significant glenoid bone loss after severe shoulder dislocation remains a topic of discussion, as there are many autograft and allograft techniques for glenoid augmentation. Several studies have identified scapular spine autograft to be a potential option for restoring glenohumeral stability, however, there is limited clinical data for this procedure. We present two cases in which patients suffered from anterior glenoid bone loss and recurrent shoulder instability who underwent open glenoid augmentation with scapular spine autograft. Both patients report a full return to activity with no functional limitations. Open glenoid augmentation with a scapular spine autograft is a viable option for patients with anterior glenoid bone loss and recurrent shoulder instability.
