Cervical Spinal Cord Injury as a Result of Axial Tension

Research to improve the understanding, prevention, and repair of spinal cord injury (SCI) is necessary in order to reduce SCI incidence, improve a patients’ quality of life, and relieve the economic impact of this injury. The authors have performed in vitro studies that examine the effects of tensile loading to the cervical spine of adult non-human primates by measuring the strains in both the vertebral column and in the spinal cord, and analyzing the injured spinal cord using histology. Current neck injury thresholds are based upon the structural failure of the vertebral column. However, neurologic SCI may occur prior to vertebral column failure in axial tension. Injury thresholds can be improved with a more in-depth understanding of the strain relationship between the vertebral column and the spinal cord. The techniques developed in this study set the groundwork for further testing which will include pediatric specimens as we attempt to recreate spinal cord injury without radiographic abnormality (SCIWORA) in the laboratory. A comparison between pediatric and adult spine biomechanics will help design biofidelic anthropometric test dummies and treatment protocols following SCI.
