Unilateral Biportal Endoscopy (UBE) for the treatment of lumbar spinal stenosis combines the advantages of both open surgery and minimally invasive surgery: ① Minimal surgical trauma: Only two small incisions of 0.8 cm are required, resulting in minimal damage to the paraspinal muscles; ② Aqueous medium surgical field: Radiofrequency can be used for effective and precise hemostasis under endoscopy, which significantly reduces blood loss; ③ Endoscopic operation: The surgical field is magnified, allowing clear and adequate exposure of the dura mater and nerves to avoid injury to important structural tissues; ④ Precise decompression: Under the above conditions, traditional surgical instruments and specialized tools such as endoscopic drills can be used to complete bilateral resection of the lamina and ligamentum flavum as well as spinal canal enlargement, achieving meticulous decompression of the central canal and lateral recess.

Posterior Lumbar Interbody Fusion (PLIF) adopts a midline posterior lumbar approach. On the basis of completing decompression of the spinal canal and nerve root canal, it resects the intervertebral disc tissue of the pathological segment and implants bone grafts (or interbody fusion cages) to achieve intervertebral bony fusion. Meanwhile, it is combined with a pedicle screw internal fixation system to maintain spinal alignment and stability, ultimately aiming to relieve neurological symptoms and restore the mechanical function of the spine.
