In recent years, the morbidity of lumbar disc herniation (LDH) has been increasing. For patients who do not respond to conservative treatment, lumbar discectomy is currently the most common surgical procedure in clinical practice. However, surgery may damage or require incision of the annulus fibrosus, which inevitably compromises the integrity of the annulus fibrosus. This not only leads to a decline in its biomechanical function but also accelerates disc degeneration, causes intervertebral space narrowing, and even leads to postoperative recurrence. How to effectively reduce the recurrence rate of LDH has gradually become a research hotspot in the field of spinal surgery. In recent years, with the significant advancement of optical electronic endoscopy and minimally invasive surgical techniques, the use of spinal endoscopic lumbar discectomy combined with annulus fibrosus suture for the treatment of LDH has become a research hotspot. In particular, annulus fibrosus suture via uni⁃portal non⁃coaxial spinal endoscopic surgery (UNSES) has demonstrated significant advantages in terms of operation duration, intraoperative bleeding volume, incision length, and prevention of postoperative complications. This paper provides a review of the current research status of annulus fibrosus suture techniques via UNSES.
