Rocking horse loosening in a superiorly unstable total shoulder

Recently we found this interesting Grashey view that nicely demonstrates superior rocking horse glenoid component loosening associated with superior instability after a total shoulder.
While no clinical information was available, the image is interesting in that it demonstrates the possible consequence when the humeral head is not centered in the prosthetic glenoid. This film also shows a substantial amount of backside cement, which we've found to predispose to glenoid component loosening.
