Figure 5: Comparative intrinsic stability <strong>of</strong> the three unused polyethylene glenoid components with a radius <strong>of</strong> curvature <strong>of</strong> 25 mm to the average intrinsic<br />
stability <strong>of</strong> the 11 cadaveric glenoid’s in their reamed 25.0 <strong>and</strong> reamed 22.5 states. The BSAs are shown in degrees.<br />
