NCT07250581

Brief Summary

The goal of this study is to explore the indications and application scope of spinal endoscopy combined with annulus fibrosus repair technology, with a focus on verifying the effectiveness of annulus fibrosus suture technology and evaluating its safety, so as to further support the promotion of annulus fibrosus repair technology in patients with lumbar disc herniation.

Outcome Measures

Primary Outcomes (4)

  • Recurrence rate

    The proportion of lumbar intervertebral disc protrusion recurring at the surgical segment within a certain period after surgery, including short-term recurrence and long-term recurrence.

    Within one year

  • Postoperative therapeutic effect

    The change of the quality of life of postoperative patients was evaluated by using the VAS(Visual Analog Score), Zero to ten points indicates the degree of pain from mild to severe

    Within one year

  • Postoperative therapeutic effect

    The change of the quality of life of postoperative patients was evaluated by using the JOA score(Japanese Orthopaedic Association), In the JOA score, a range from 0 to 29 points is interpreted as indicating a progression from poor to good.

    Within one year

  • Postoperative therapeutic effect

    The change of the quality of life of postoperative patients was evaluated by using the ODI (Oswestry Disability Index), 0% represents the least severe condition, while 100% indicates the most severe condition.

    Within one year

Secondary Outcomes (1)

  • Nerve injury

    Within one year
