Abstract

Abstract : ➢ 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.
