To investigate the cervical spinal canal diameters variance under positional MRI, and also the relationship between cervical canal diameter variance rate and grade of degeneration. ⋯ C5/6 and C4/5 is of higher risk of suffering SCI than other levels, C4/5 level predispose SCI at earlier stage than C5/6, patients presenting with intermediate signal and slight decreased disc height on T2 weighted MRI at C4/5 level should be paid attention.

We present a case of C6 mesenchymal chondrosarcoma and discuss safe posterior to anterior approach subtotal en-bloc spondylectomy. ⋯ Based on the Grand Round case and relevant literature, we discuss the case of mesenchymal chondrosarcoma occurring from the C6 cervical spine treated with cervical subtotal en-bloc spondylectomy. Successful en-bloc resection of the tumor was achieved using posterior to anterior approach.

This project describes a morphology-based subaxial cervical spine traumatic injury classification system. Using the same approach as the thoracolumbar system, the goal was to develop a comprehensive yet simple classification system with high intra- and interobserver reliability to be used for clinical and research purposes. ⋯ The AOSpine subaxial cervical spine injury classification system demonstrated substantial reliability in this initial assessment, and could be a valuable tool for communication, patient care and for research purposes.
