The five mismatches are depicted, at five degrees of elevation in the scapular plane (15 deg, 30 deg, 60 deg, 90 deg, and 120 deg). For each case, the contact area for an intact-muscle shoulder (black line) and a shoulder with a subscapularis tear (gray line) are drawn. The centers of pressure are represented by the cross sign.

The figure shows the values for the 6.4 mm mismatch, corresponding to a combination of a medium glenoid size and a Ø51 mm humeral head size. COP position is represented in black for the intact-muscle shoulder, and in gray for the subscapularis-tear shoulder. Figure Legend:
