Clinical outcomes of unilateral biportal endoscopic discectomy for the treatment of far lateral lumbar disc herniation: a retrospective comparative study

 

Purpose

This retrospective study aims to evaluate the efficacy and safety of unilateral biportal endoscopic discectomy (UBED) in patients with far lateral lumbar disc herniation (FLLDH).

Methods

A total of 25 patients with single-level FLLDH who underwent UBED between April 2023 and January 2024 were retrospectively analyzed, while 30 patients with paracentral LDH served as the control group. Primary outcomes were assessed using operation time, hospital stay, volume of drainage, complications, postoperative hospitalization duration, visual analogue scale (VAS) scores for back pain (VAS-BP) and leg pain (VAS-LP), the Oswestry Disability Index (ODI), and the modified MacNab criteria. Demographic, symptom-related, and radiographic data were also analyzed.
