Table 3 Accuracy of reproducing the intraoperative validated angle as assessed by the post-operative radiographs1. Data are presented as means ± standard deviation (95% confidence intervals)
Intra-operative Validated Angle | Post-operative Radiographs | P-value | Mean Absolute Error | |
|---|---|---|---|---|
Anteversion | 19.7° ± 3.0° (18.2° – 21.1°) | 21.0° ± 3.9° (19.04° – 22.9°) | 0.241 | 3.1° ± 2.5° (1.9° – 4.4°) |
Inclination | 40.6° ± 2.2° (39.5° – 41.6°) | 43.56° ± 4.13° (41.5° – 45.6°) | < 0.001 | 3.9° ± 2.2° (2.8° – 5.0°) |
