Combined anterior and posterior instrumentation in severe fracture-dislocation of the lower cervical spine with help of navigation: a case report.

The authors report a case of severe fracture-dislocation of C6-C7 with dural and spinal cord damage causing quadriplegia. The patient was treated surgically with circumferential stabilisation. Intense spinal instrumentation with pedicle screw fixation in addition to anterior decompression and plate fixation was essential for restoring the original vertebral column. This technique of internal fixation provided a more rigid anchor, however the risk to the neurovascular structures could not be completely eliminated. Therefore, the combined anterior and posterior stabilisation assisted with a navigation system was a safer and reasonable surgical treatment for this patient with severe cervical injuries.
