Lumbar disc herniation is a common clinical disease with multiple morbidities. Patients suffer from back pain and leg pain, which seriously affect their work and life. 90% of patients can be cured by regular conservative treatment, while 10% of patients need surgical treatment. There are various methods of surgery, minimally invasive lumbar discoscopy is suitable for simple lumbar disc herniation, while for lumbar disc herniation combined with spinal stenosis requires extensive decompression, but decompression can lead to narrowing of the intervertebral space, narrowing of the nerve root canal, re-compression of the nerve root and recurrence of back and leg pain! In order to prevent the occurrence of long-term complications, we have carried out lumbar discectomy interbody fusion implantation since 2000, which has maintained the height of the intervertebral space and stabilized the vertebral body, preventing the occurrence of postoperative complications and receiving excellent results.
