The preoperative and postoperative imaging data of patient who received VTT involving TELF. (A) preoperative sagittal MRI image showed L4-L5 very highly up-migrated lumbar disc herniation. (B) postoperative sagittal MRI image showed that the protruding tissue in the spinal canal was completely removed. (C) preoperative sagittal CT reconstruction. (D) postoperative sagittal CT reconstruction demonstrated the ventral part of SAP of the inferior vertebra be partially resected, not offending the articular surface. (E) preoperative axial MRI image showed L4-L5 very highly up-migrated lumbar disc herniation located in left side. (F) postoperative axial MRI image showed that the protruding tissue in the spinal canal was completely removed. (G) preoperative axial CT at L4 level. (H) postoperative axial CT demonstrated the trench which we dig in the posterior surface of L4 vertebral body
