Study design: Retrospective case analysis.
Purpose: To investigate the application of neuroelectrophysiological monitoring in Posterior
Percutaneous Endoscopic Cervical Discectomy (P-PECD).
Overview of literature: There is an injury risk of nerve root and spinal cord during P-PECD.
Intraoperative neuroelectrophysiological monitoring can dynamically monitor the function of the
nerve roots and spinal cord, providing real-time data for the surgeon to avoid the risks during
Methods: A retrospective review was performed on 25 patients in an average of 45.9 years +/- 10.9
years old with single segment of cervical disc herniation between May 2018 and June 2019. All the
patients underwent a P-PECD and Free-run Electromyography (f-EMG), Motor Evoked Potential
(MEP), and Somatosensory Evoked Potential (SEP) were used to monitor the function of nerve
roots and spinal cords in the operation. The monitoring results were recorded and analyzed.
Results: When placing operation channels and grinding vertebral plates, f-EMG displayed no
obvious reactions, MEP could be induced on both sides, and bilateral SEP waveforms were stable,
showing the function of nerve roots and spinal cords was normal. f-EMG detected a series of changes
in the motion unit waveform on the patient's diseased side when the removal of the ligamentum
flavum and the inner layer of the vertebral plate. The waveforms of f-EMG returned to normal
following the surgical tools were removed from the nerve root and dural sac. The double-sided
waveforms can be induced in MEP, and were stable in SEP. The true positive rate was 96% and the
false negative rate was 4% during the operation. No nerve damages were found in all patients.
Conclusion: Combined applications of free-EMG, MEP and SEP can provide objective functional
indicators of the nerve root and spinal cord for surgery, thereby improving the efficiency and safety
of the operation.
