Comparison of glenoid lateralization (bony increased offset) reverse total shoulder arthroplasty) and humeral lateralized (cementless, curved, short-stem) reverse shoulder arthroplasty. Radiologic findings show the inserted bone graft on the glenoid in the glenoid lateralization design (A). A 4-year follow-up X-ray showing Grade 3 scapular notching on the scapular neck (B). Intraoperative photo showing that the autograft was well attached to the glenoid long post baseplate and inserted into the native glenoid (C). Radiologic findings showing the curved, short-stem insertion in the humeral lateralization design (D). A 3-year follow-up X-ray showing Grade 3 scapular notching on the scapular neck (E). Intraoperative photo showing that the chip bone autograft was inserted into the proximal humerus before stem insertion to prevent early humeral stem loosening (F)
