Abstract
This study sought to define a point on the anterior glenoid surface to serve as a marker for glenoid orientation and to present the concept of a glenoacromial version angle. Twenty fresh-frozen cadaver scapulas were examined. A line perpendicular to the glenoid surface exited the anterior scapular cortex in all specimens at an average distance of 29.3 +/- 3.9 mm. The average glenoacromial version angle was 60 degrees +/- 110 degrees. These numbers may allow better intraoperative assessment of glenoid version.
