Abstract

STUDY DESIGN:

Retrospective review.

OBJECTIVE:

To report on the safety of repetitive transcranial electric stimulation (RTES) for eliciting motor-evoked potentials during spine surgery.

SUMMARY OF BACKGROUND DATA:

Theoretical concerns over the safety of RTES have hindered broader acceptance of transcranial electric motor-evoked potentials (tceMEP), despite successful implementation of spinal cord monitoring with tceMEPs in many large spine centers, as well as their apparent superiority over mixed-nerve somatosensory-evoked potentials (SSEP) for detection of spinal cord injury.

METHODS:

The records of 18,862 consecutive patients who met inclusion criteria and underwent spine surgery with tceMEP monitoring were reviewed for RTES-related complications.

RESULTS:

This large retrospective review identified only 26 (0.14%) cases with RTES-related complications; all but one of these were tongue lacerations, most of which were self-limiting.

CONCLUSIONS:

The results demonstrate that RTES is a highly safe modality for monitoring spinal cord motor tract function intraoperatively.
