Figure 2.

A 12-year-old female presented with CS received posterior scoliosis correction and fixation surgery. Surgery has led to abnormal neurological function. Electrophysiological abnormality was monitored by TcMEP (B) of MIOM, while SSEP (A) was normal. The change was reversed by appropriate measures and returned to baseline at the end of the surgery. No additional postoperative neurological injury was observed. CS = congenital scoliosis, MIOM = multimodal intraoperative monitoring, SSEP = somatosensory evoked potential, TcMEP = transcranial motor evoked potential.
