Table 4 Data of intraoperative evoked potential events and outcomes in the non-osteotomy group.
Case | Group | Gender | Age | Blood loss (mL) | EP events | Intraoperative management | Postoperative spinal cord function | Nerve injury outcome | Complication |
---|---|---|---|---|---|---|---|---|---|
1 | A1 | Female | 10 | 340 | SSEP+MEP change at pedicle screw insertion | Recovery after removing screw and lifting blood pressure | Frankel grade E | Frankel grade E | None |
2 | A1 | Female | 12 | 100 | MEP change at pedicle screw insertion | Recovery after removing screw and lifting blood pressure | Frankel grade E | Frankel grade E | None |
3 | A1 | Female | 11 | 370 | MEP change at correction | Recovery after reducing correction | Frankel grade E | Frankel grade E | None |
4 | A2 | Female | 13 | 600 | SSEP change at correction | Recovery after reducing correction | Frankel grade E | Frankel grade E | None |
EP – evoked potential; MEP – motor evoked potential; SSEP – somatosensory evoked potentials; DNEP – descending neurogenic evoked potentials. |
