From: No correlation between radiolucency and biomechanical stability of keeled and pegged glenoid components

Fig. 4

With an eccentric inferior force, we would expect a negative displacement for the component and a positive displacement in the superior aspect of the glenoid (a), but we saw a negative displacement (b) suggesting a deformation phenomenon. Furthermore, the anchor design would support this phenomenon, showing a more compact anchorage in the keeled component with equal force distribution (c) compared to the pegged glenoid with an unequal force distribution (d)
