- Abstract:
- Objective To compare the results of intraoperative neurophysiological monitoring (IONM) during posterior spinal correction surgery for adolescent idiopathic scoliosis (AIS) patients with different curve patterns and examine the impact of curve pattern on IONM results.Methods From June 2015 to December 2019,400 AIS females undergoing operations were retrospectively reviewed,including single thoracic curve (ST,n=100),thoracolumbar/lumbar curve (TL/L,n=100),double thoracic curve (DT,n=100) and double major curve (DM,n=100).Absolute values of latency and amplitude for somatosensory evoked potential (SSEP) and transcranial electric motor evoked potential (TCeMEP) between bilateral lower limbs and the incidence of asymmetric SSEP between patients with different curve patterns were compared.Results The latencies and amplitudes of SSEP and TCeMEP demonstrated marked asymmetry between left and right lower limbs (P>0.05).The latency of TCeMEP was longer in left lower limb than right lower limb in TL/L group (P=0.032) while the latencies of SSEP-P37(t=3.166,P=0.002) and SSEP-N45 (t=4.089,P<0.001) were significantly longer in left lower limb than right lower limb in DM group.The incidence of asymmetric SSEP was 33% in ST group,34% in TL/L group,27% in DT group and 37% in DM group(P=0.495).Conclusion Asymmetric latencies and amplitudes of SSEP and TCeMEP between bilateral lower limbs are frequently noted in AIS patients.Therefore curve pattern is not a risk factor for asymmetric SSEP in AIS.
