Posterior Humeral Avulsion of the Glenohumeral Ligament: A Critical Analysis Review

Research output: Contribution to journalReview articlepeer-review


Posterior humeral avulsions of the inferior glenohumeral ligament represent an increasingly recognized but likely underdiagnosed source of posterior shoulder instability and pain.Injuries are commonly reported in athletic individuals who have sustained injury by either traumatic or atraumatic mechanisms; the ligament is most susceptible to injury with the shoulder in flexion, adduction, and internal rotation.Posterior humeral avulsions of the glenohumeral ligament often occur in the setting of concurrent injuries to the posterior or inferior labrum.Diagnosis is often challenging due to nonspecific symptoms and physical examination findings; a magnetic resonance arthrogram generally is utilized to identify avulsion from the humeral attachment; however, a definitive diagnosis is often made at the time of arthroscopic evaluation.In patients with persistent discomfort and limitations following nonoperative management, operative fixation, primarily utilizing arthroscopic techniques, can be performed to restore motion and glenohumeral stability.
