Retrospective Analysis of EMG-evoked Potentials in Cortical Bone Trajectory Pedicle Screws

Conclusions:
tEMG testing is effective for medial breaches in CBT screws. In addition, there is evidence that bicortical placement of these screws causes lower stimulation values due to distal breach. Importantly, it seems that this is due in part to stimulation of the exiting nerve root at the level above.
