“…4,33,43 Surgical/implant factors affecting outcomes include both technical factors (e.g., glenosphere positioning and tilt, humeral and glenosphere version) and implant-related factors (e.g., glenosphere diameter and lateral offset, humeral offset and rotation, polyethylene insert eccentricity, constraint and thickness). 3,9,16,[20][21][22][25][26][27][31][32][33] Surgeons should consider the effect of hardware selection and placement because excessive tension or offset after reverse arthroplasty may be associated with deltoid-related pain, restriction in motion, or acromial fractures. 8,14,34,42,50 To the contrary, insufficient tension or offset may be associated with instability or increased risk for scapular notching.…”
