The influence of anterior or posterior pelvic tilt on anteversion (n = 619)
| Pelvic tilt | Hips | Adjust* | Adjust coefficient† |
|---|---|---|---|
| Posterior tilt greater than 10° | 78 (12.6%) | 10.4 ± 2.5 (7–20) | 0.8 |
| Posterior tilt 1° to 9° | 250 (40.4%) | 3.6 ± 2 (1–9) | 0.8 |
| No tilt (0°) | 53 (8.6%) | NA | NA |
| Anterior tilt 1° to 9° | 208 (33.6%) | −3.3 ± 1.8 (−7 to −4) | −0.8 |
| Anterior tilt greater than 10° | 31 (4.8%) | −8.3 ± 2.1 (−13 to −4) | −0.7 |
* Adjusted anteversions (expressed as average ± standard deviation with range in parentheses) when converting the anteversion from the anterior pelvic plane to the coronal plane; a positive value is increase and a negative value is decrease; †how many degrees of the anteversion are adjusted by the change of 1° of anteroposterior pelvic tilt; a positive value is increase and a negative value is decrease; NA = not applicable.
