The Effect of the Loading Condition Corresponding to Functional Shoulder Activities on Trabecular Architecture of Glenoid

Schematic of the location of the regions of interest (ROIs) in the mediolateral (above), supero-inferior (center), and anteroposterior (bottom) views

Predominant trabecular directions (average angle) and their distributions (standard deviation) in the ROIs. The values are obtained from 12 cadaveric specimens. Straight, dashed, and dotted arrows represent the predominant directions in the upper, bare, and lower regions, respectively. The values in the first, second, and third rows in the ROIs are the predominant numerical angles in the upper, bare, and lower regions, respectively.

The trajectories (direction) and magnitudes of the primary principal stresses computed from the FE model under the validation procedure. The straight, dashed, and dotted arrows on each ROI represent the direction of the primary principal stress in the upper, bare, and lower regions, respectively. The values in the first, second, and third rows, to the right of each ROI, are the numerical values of the primary principal stress directions in the upper, bare, and lower regions, respectively. The values in the first, second, and third rows below each ROI indicate the principal stress magnitudes (MPa) in the upper, bare, and lower regions, respectively.
