Case 3, male, 22 years old, severe rigid thoracolumbar deformity. a, b, c and d Preoperative diagnosis was kyphosis Cobb angle 102° and scoliosis Cobb angel 118° by profile, X-ray after bending, three-dimensional CT and printing model imaging. e Intraoperative osteotomy, pedicle screws fixation and correction. Yellow arrow represents the intact and slack L1 nerve root. f Normal waveforms occurred in SEP and MEP during surgery. g Postoperative kyphosis and scoliosis Cobb angle was corrected to 32° and 35°, as shown in X-ray and three-dimensional CT images
