Correlation Between Single-Pulse and Pulse-Train Stimulation During Neuromonitoring of Thoracic Pedicle Screws in Scoliosis Surgery.

Background: The use of thoracic pedicle screws (TPSs) during scoliosis surgery entails an inherent risk of neurological deficit. Triggered electromyography (t-EMG) is an accurate neuromonitoring test for detection of malpositioned TPSs. However, single-pulse (SP) t-EMG stimulation has shown variable capability for detecting medial pedicle breaches, while pulse-train (PT) t-EMG could be more accurate.
