Article Figures & Data
Figures
- Figure 1
(a) Preoperative clinical photograph showing “cock robin” position and (b) immediately postoperative clinical photograph showing resolution of neck tilt. (c–e) Postoperative images at 2 years show no residual deformity and minimal restriction of rotation.
- Figure 2
Preoperative MRI: (a) Coronal scans showing lateral tilt. (b) T2 weighted axial scans showed intact transverse alar ligament.
- Figure 3
Preoperative x-ray: (a) Note eccentric position of the odontoid. (b) Lateral x-ray showing rotation at C1-2 with elliptical appearance of the C1 arch.
- Figure 4
(a) Preoperative computed tomography angiography with 3-dimensional recon showing atlantoaxial rotatory dislocations. (b) Parasagittal view showing dislocation of facet joints. (c) Axial view showing maintained atlanto-dental interval with rotatory atlanto-axial dislocation.
- Figure 5
(a) Initial exposure depicting severe rotation of sub-axial spine in relation to C1. (b) Following opening of joint spaces C1-2 realignment noted. (c) Postoperative computed tomography scan.
- Figure 6
Postoperative x-ray images at 2 years in extension, neutral, and flexion.
- Figure 7
Postoperative MRI images at 3 years: (a) Sagittal scans of brainstem. (b) T2 weighted axial scans at foramen magnum level. (c) T2 weighted axial scans at C2 level.
