Glenoid retroversion is the abnormal posterior angulation of the articular surface of the glenoid of the scapula and is of importance as it predisposes to posterior glenohumeral instability and tears of the posterior labrum.
The normal shoulder demonstrates neutral glenoid version, where the articular surface of the glenoid is perpendicular to the axis of the scapular body.
The glenoid version angle can be calculated via various methods.
Treatment and prognosis
There is no standard proven surgical treatment and as such numerous surgical methods have been trialled with various successes, including soft-tissue repairs, glenoplasty, and bone augmentation techniques.
The rate of success of the surgical treatment is inversely proportional to the severity of retroversion.
