Cervical Posterior Spinal Fusion
PROCEDURE
Stabilization of posterior spine with lateral mass screws, typically accompanied with a laminectomy and decompression.
ELECTRODES
Corkscrews - 10: Fz, Cz, CP3, CP4, CS5, M1, M2, M3, M4, GND
Needles - 20 (40);Trapezius, Deltoid, Biceps, Triceps, Brachioradialis, Thenar/Hypothenar, Tibialis Anterior/Gastrocnemius, Extensor Hallucis/Abductor Hallucis, ULN x 2, PTN x 2, GND
MODALITIES
EMG - All muscle groups
tEMG - Cervical muscle groups
SEP - UlN, PTN, cortical and subcortical
MEP - Responses from all muscle groups listed
EEG - 2 Channels: Fpz - CP3, FPz - CP4
T04 - For anesthetic depth of muscle relaxant
NOTES:
Additional electrodes can be placed at Erb's point for accuracy of stimulus delivery for SEPs, Xiphoid for extra cervical coverage of vagus nerve innervation. A pre-rotation to prone baseline may be requested by the surgeon, balance anesthesia accordingly.
