Key result
Total shoulder arthroplasty using a cemented glenoid component significantly improved mean ASES scores from 30.3 to 81.3 (P<.001) and VAS pain scores from 8 to 1 (P<.001) at 50.2 months.
Why the study?
What types of glenoid component motion occur early after TSA, and do they correlate with radiolucencies and clinical outcomes?

Case report shows score gains with cemented glenoid TSA; leaves open micromotion-radiolucency correlations and generalizability.
Observational (n=11)
What types of glenoid component motion occur early after TSA, and do they correlate with radiolucencies and clinical outcomes?
Absolute Event Rate: 81.3% vs 30.3%
p-value: p=<.001
Radiolucencies appearing around glenoid components after total shoulder arthroplasty are associated with high levels of rotational micromotion.
Streit et al. (2015) conducted an observational in Total shoulder arthroplasty (n=11). Total shoulder arthroplasty using a cemented, all-polyethylene glenoid component vs. Preoperative baseline was evaluated on American Shoulder and Elbow Surgeons (ASES) score (p=<.001). Total shoulder arthroplasty using a cemented glenoid component significantly improved mean ASES scores from 30.3 to 81.3 (P<.001) and VAS pain scores from 8 to 1 (P<.001) at 50.2 months.
