Experimental Studies on the Spinal Cord Evoked Potentials in Cervical Spine Distraction Injuries

  • Conference paper
Spinal Cord Monitoring and Electrodiagnosis

Summary

Effects of stepwise distraction of the spinal cord on the spinal cord evoked potentials (SEP) were studied in cats. During the distraction between two adjacent cervical vertebrae, the SEP was examined upon single electric shocks to the lower spinal cord level (ascending SEP). The SEP was recorded from three points in the epidural space of the distracted spinal cord. Among the three sites the central site showed suppression of the ascending SEP earliest and most severely. The critical point for reversibility of spinal cord function should be set at a 30% amplitude decrease from the control SEP. Monitoring of the SEP at the central site of two cervical vertebrae seems to be best during corrective surgery to avoid possible damage to the spinal cord.
