a Sagittal CT showed reduction and restoration 1 month after operation. b MRI sagittal T2-weighted films 1 month after operation showed ventral medullary decompression with CMA recovery to approximately 152.00°. c At 13 months follow-up, sagittal CT showed no instrument loosening, no loss of reduction, and evidence of bony fusion. d At 13 months follow-up, MRI sagittal T2-weighted image showed CMA recovery to approximately 162.00°. e, f Postoperative X-ray showed good internal fixation
