The difference in the functional outcomes, ROM, and sagittal alignment parameters according to the 2 groups.
| Last Follow-Up | Neck Disability Index | VAS score | ROM | Cobb C2–C7 | Spinocranial Angle | |
| Neck Pain | Radicular Pain | |||||
| Anterior group (n = 15) | 13.1 (9.7–22) | 2.7 (1.9–3.4) | 2.8 (2.3–3.3) | 10.6° (6.9°–14.3°) | 13.2° (8.8°–17.4°) | 76.7° (72°–84.4°) |
| Posterior group (n = 10) | 14.9 (10.4–21.7) | 2.7 (1.5–2.9) | 2.1 (1.4–2.6) | 11.1° (9.5°–12.6°) | 18.3° (9.4°–22.7°) | 70.9° (65.8°–7.1°) |
| P value | 0.57 | 0.93 | 0.97 | 0.89 | 0.19 | 0.13 |
Abbreviations: ROM, range of motion; VAS, visual analog scale.
