Table 2 Reduction in sacroiliac joint range of motion (°) between transarticular and inline orientation groups
| Orientation | Implants (positions) | Superior implant ending point | Reduction in SI joint ROM (°) (%) | ||
| Flexion-extension | Lateral bending | Axial rotation | |||
| Transarticular vs inline | 3 (S, M, I) | Mid-ala | 0.11° (16%) | 0.04° (9%) | 0.07° (17%) |
| Mid-sacrum | 0.11° (17%) | 0.03° (7%) | 0.07° (18%) | ||
| 2 (S, -, I) | Mid-ala | 0.13° (16%) | 0.05° (11%) | 0.08° (18%) | |
| Mid-sacrum | 0.11° (16%) | 0.04° (9%) | 0.08° (20%) | ||
| 2 (S, M, -) | Mid-ala | 0.16° (16%) | 0.05° (10%) | 0.09° (18%) | |
| Mid-sacrum | 0.12° (16%) | 0.04° (9%) | 0.08° (19%) | ||
| 2 (-, M, I) | -1 | 0.15° (16%) | 0.06° (11%) | 0.09° (16%) | |
| 1 (-, M, -) | -1 | 0.21° (16%) | 0.05° (8%) | 0.03° (4%) | |
| 1 (-, -, I) | -1 | 0.20° (16%) | 0.07° (10%) | 0.06° (8%) | |
| Median (°) (Range) | 0.13° (0.11-0.21) | 0.05° (0.03-0.07) | 0.08° (0.03-0.09) | ||
