With the developments in techniques and instruments in spinal surgery, spinal surgeons have increasingly begun to correct the complicated deformity cases. As a result, the number of spinal cord damage and associated neurological deficiency in deformity surgeries has increased. In order to reduce these complications, the use of intraoperative neuromonitoring has gained popularity in the last two decades, using the latest technology of today, Somatosensory Evoked Potential (SEP), Motor Evoked Potential (MEP), Intraoperative Electromyography (EMG) techniques improved surgical outcomes by reducing the risk of iatrogenic neural injury. It has been reported that the combined use of multimodal neuromonitoring SEP+MEP has the highest sensitivity and specificity in spinal deformity surgeries.
