Percutaneous unilateral biportal endoscopy versus uniportal endoscopy for lumbar spinal stenosis: a single-centre, prospective, non-randomised cohort trial protocol.

ABSTRACT:

Introduction

Unilateral biportal endoscopic (UBE) technique and uniportal endoscopic (UE) technique have both been used to treat lumbar spinal stenosis (LSS) with satisfactory outcomes. Although previous studies have reported no difference in clinical outcomes between UBE and UE techniques, the evidence was weak due to the lack of a prospective design. Therefore, the present prospective study aimed to compare the efficacy and safety of UBE and UE for treating patients with LSS.

Methods and analysis

This single-centre, prospective, non-randomised cohort trial is designed to compare the efficacy and safety of UBE and UE in treating patients with LSS. We will include 120 participants (60 per group) with single-level or double-level LSS. The primary outcome will be determined us
