Clinical value of a novel V-shaped annular suture under unilateral biportal endoscopy: a retrospective comparative study with the traditional I-shaped suture

ALAng LiKWKun WangXXXin Xu

Key Points

  • The study aims to compare the clinical effectiveness of a novel V-shaped annular suture to a traditional I-shaped suture in lumbar repair.
  • Conducted a retrospective comparative analysis between the two suture techniques.
  • Evaluated closure stability and postoperative recurrence rates.
  • Utilized unilateral biportal endoscopy for the surgical procedure.
  • The V-shaped annular suture showed improved closure stability.
  • There was a lower risk of postoperative recurrence with the V-shaped technique.
  • Both techniques were found to be safe and effective despite the V-shaped suture being more technically demanding.

Abstract

The V-shaped annular suture provides improved closure stability and may reduce the risk of postoperative recurrence compared with the traditional I-shaped suture. Although technically more demanding, this technique is safe and effective, showing promising clinical applicability for lumbar annular repair.
