Figure 1. Digitised landmarks used to define the relative position of the glenoid bone relative to the scapular blade.

On the left is shown the digitized points used to establish the glenoid surface plane and the scapula plane. On the right is shown the digitized points outlining the glenoid surface and scapula. Also shown are the lines labelled LBL (Lateral Border Line) and SFL (Supraspinatus Fossa Line) used to determine the scapula plane as well as the inclination.
