Abstract：【Objective】To study the applied anatomy of lumbar intervertebral disc nucleus pulposus in the treatment of lumbar disc herniation.【Methods】Ten adult cadaver specimens of lumbar spine were selected to measure the length, width and height of the lumbar intervertebral foramen. In addition, 46 patients with transplanted nucleus pulposus resections under their lumbar discs who were in our hospital were selected to evaluate the curative effect.【Results】From L1to L5, the intervertebral foramen width gradually decreased (P<0.05), the height gradually increased (P<0.05), and the distance from the lower edge of nerve root to the lower edge of intervertebral foramen gradually increased (P<0.05). The same intervertebral foramen width, height, length, and the distance from the inferior edge of nerve root to the lower edge of intervertebral foramina had no statistical significance (P>0.05). There was no significant difference between the medial and lateral sagittal plane of the pedicle, upper and lower articular process to the sagittal plane, and distance from the isthmus of the vertebral arch to the sagittal plane on the left and right sides (P>0.05). The postoperative clinical efficacy rate was 93.5% (43/46) in the 46 patients. The JOA score and the height of the intervertebral space were significantly higher than those before operation (P<0.05).【Conclusion】The intervertebral foramen has its unique anatomical structure. Cervical intervertebral foramen endoscopic discectomy has good clinical curative effect, simple operation procedure, and less surgical trauma. It is a better surgical method for the treatment of lumbar disc herniation.
