Trends in 3D Planning and Navigation in Shoulder Arthroplasty: Analysis of 70,137 Cases Over 8 Years

This study aims to retrospectively evaluate TSA planning patterns over an 8-year period, examining nearly 70,000 cases. For both aTSA and rTSA, over half of the planned cases are navigated, with most adhering to the planned procedure. Practitioners who plan both procedures are more likely to navigate the case, particularly in aTSA. For aTSA, neutral inclination and slight retroversion are consistent targets. In rTSA, 0° inclination is the aim, with significant inferior corrections and greater version adjustments using posterior augments. Augmented implants help maintain planned residual angles while addressing severe deformities. No notable differences were observed between low- and high-volume surgeons.
