Three-Dimensional Quantitative Analysis of Spinal Cord Dynamics during Anterior Cervical Decompression and Fusion
This first quantitative three-dimensional analysis of spinal cord motion during ACDF revealed that craniocaudal sliding motion exceeded anteroposterior pulsation. The preferential direction from cranial to caudal indicated the brain pulsation to be the major origin. The C4/5 level exhibited maximum anteroposterior motion, which may be related to C5 palsy pathophysiology. Increased cervical lordosis promoted both types of motion, particularly craniocaudal sliding. These findings may guide intraoperative neural assessments during cervical decompression procedures.
