Odontoid fractures: PTGWT (mean: 17.4, median: 17°, SD: ±10.1, p<0.0001) showed a significant improvement of angular deviation but not with surgical treatment (mean: 3.1, median: 1°, SD: ±7.5, p=0.24). Subluxation fractures: Preoperative reposition of angular deviation was not as successful (mean: 8, median: 4°, SD: ±10.9, p=0.10) as the intraoperative results (mean: 18.25, median: 20.5, SD: ±14.66, p=0.01).
