Glenoid avulsion of the glenohumeral ligaments as a cause of recurrent anterior shoulder instability.

摘要

Although the Bankart lesion is accepted as the primary pathology responsible for recurrent shoulder instability, recognition of other soft-tissue lesions has improved the surgical treatment for this common problem. Whereas humeral avulsion of the glenohumeral ligaments has been acknowledged as a cause of anterior shoulder instability, we have not found any reported cases of glenoid avulsion of the glenohumeral ligaments. We describe 3 cases of recurrent anterior shoulder instability due to glenoid avulsion of the glenohumeral ligaments. The avulsed ligaments were repaired to the labrum and glenoid, restoring the glenohumeral ligament-labral complex.
