“Glenoid” is Latin for “pear shaped”—an apt description. The glenoid has a relatively flat subchondral surface with much of the depth of the glenoid made up by articular cartilage and the circumferential labrum. The average superior tilt is 5° and the mean retroversion is 6°, though the version to the axis of the scapular body can vary from 5° of anteversion to 10° of retroversion.
