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

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.
