Intradural occupational disease accounts for approximately 15% of CNS occupational disease and is divided into three categories: epidural, extramedullary subdural, and intramedullary tumors according to their location. Epidural lesions are commonly metastatic cancer, malignant lesions, and inflammatory diseases; intramedullary diseases are commonly ventricular meningioma and glioma; extramedullary subdural lesions are the most common, and several benign lesions, including neurofibroma and spinal meningioma, are the most common. Surgery is the most effective method of treating occupying intradural disease. In the past, neurosurgeons did not pay attention to the stability of the spine and often used total laminectomy to remove intradural tumors, resulting in a lack of spinal stability, kyphosis and other consequences, and patients often had local pain, soreness, deformity and other symptoms, as well as leaving postoperative dead space and complications of infection (Figure 1). In recent years, as the concept has been updated neurosurgeons are paying more and more attention to the stability of the spine. The three-column theory of the spine now considers that the stability of the spine is supported by three columns: (1) the anterior column: the anterior longitudinal ligament, the vertebral body, and the anterior and middle 2/3 of the disc; (2) the middle column: the posterior longitudinal ligament, the vertebral body, and the posterior 1/3 of the disc; and (3) the posterior column: many structures behind the pedicle (including the articular eminence, the ligamentum flavum, the supraspinous ligament, and the interspinous ligament). Maintaining the stability of the spine during surgery, or restoring as much stability as possible to the disrupted spine, is an issue that must be addressed by the neurosurgeon during the removal of intravertebral tumors. Current methods of maintaining spinal stability include reducing damage to stability and reducing surgical invasiveness, commonly using a hemivertebral approach to remove the tumor (Figure 2), or even using the natural channel of the tumor without removing the vertebral plate; if invasion of stability is necessary, then repairing the stability of the spine as much as possible. The most common method is spondylolisthesis laminoplasty, in which the lamina and ligaments are cut down and returned after surgery to maintain spinal stability (Figure 3). In cases of severe bone destruction, nail rod system fixation is also required.
