Figure 2: Grade B seating - Immediate postoperative anteroposterior radiograph (a), axillary radiograph (b), and preoperative axial computed tomography scan with measured retroversion (c) illustrating an example of Grade B glenoid seating following total shoulder arthroplasty. Preoperative retroversion was incompletely corrected, leaving an uncontained area of the posterior glenoid which was filled with cement (red arrow). Incomplete contact was noted in just over 25% of the glenoid seen on the axillary radiograph
