Lumbar disc herniation is a common clinical condition, with a predilection for age 20-50 years, mainly manifesting as low back and leg pain. The traditional treatment method is laminectomy for disc nucleus pulposus removal, but after surgery some patients have recurrence of disc herniation and need to operate again; some other patients have intervertebral degeneration and instability, resulting in back pain and need to operate again for fixed fusion. Therefore, at present, decompression and fixed fusion is often used for patients with huge disc herniation requiring extensive laminectomy that may cause intervertebral instability, as well as for patients with recurrent recurrences and with intervertebral instability. However, although the incidence of postoperative lumbar pain is reduced in this procedure, patients experience stiffness and weakness in the lumbar region, and the incidence of degeneration of the adjacent segment is significantly increased. Some patients have undergone a second, third, or even fourth surgery due to the prominence of degeneration of the adjacent segmental discs. To overcome the disadvantages of spinal fusion, the Dynesys Dynamic Stabilization System was created. This system adopts inter-arch dynamic fixation and preserves the synovial joint, which not only maintains a certain degree of stability between the vertebral bodies and effectively avoids the disc to avoid recurrence of herniation, but also preserves the flexion and extension mobility of the intervertebral joints, so that the patient’s postoperative lumbar stiffness is significantly reduced and the flexion and extension function is greatly preserved, and the incidence of degeneration of the adjacent segments is greatly reduced. It has been applied for 16 years abroad and 13 years in China with satisfactory results.
