Material and Method
The authors collected the data from the
patients who had undergone chest or shoulder
computer tomographic imaging at the Department of
Radiology, Phramongkutklao Hospital between
March and July 2012. The CT images then had beenreconstructed into 3D image. The authors rotated the
reconstruct glenoid to the so-called En face view. The
bare spot was used as a reference for centering the
imagine circle. The circle was then drawn at the same
time trying to keep the circumference of the circle parallel
with the inferior edge of glenoid as possible. Then the
glenoid was measured in both anteroposterior and
superoinferior directions in millimeters by using the
landmark from the bare spot of the glenoid as a
reference
