T2-weighted sagittal MRI scans. In the early phase of the disease, only the luxation of C1-C2 seems relevant (A). The follow-up MRI reveals basilar impression (B).

The postoperative CT scan showed the reconstruction of the sagittal alignment and a correct position of implanted material and reposition of C0-C2 with regularly angulation in all planes (Figs 1, 2, 3).
The importance of close radiological follow-up is illustrated here. The sagittal and transversal CT scan showed an increase in C0/C1 subluxation over a period of 4 months (column 1 and 2). The postoperative sagittal CT scan confirmed successful dorsal decompression and reconstruction of the sagittal alignment (column 3).

The postoperative CT scan showed the reconstruction of the sagittal alignment and a correct position of implanted material and reposition of C0-C2 with regularly angulation in all planes (Figs 1, 2, 3).
Two years postoperatively, plain X-ray shows unchanged position of material and no evidence for resubluxation.
