Multicenter Clinical Randomized Controlled Trial of Unilateral Biportal Endoscopic Spinal Surgery for Degenerative Grade 1 Spondylolisthesis Complicated With Lumbar Spinal Stenosis

The research objective of this project is to clarify and compare the efficacy of the unilateral biportal endoscopy (UBE) technique and traditional open decompression, fusion and internal fixation surgery in the treatment of patients with Grade Ⅰ degenerative spondylolisthesis complicated with central spinal canal stenosis through high-quality, prospective, multicenter randomized controlled trials (RCTs), so as to provide high-level clinical research evidence for the expansion of UBE technique indications and its technical promotion.
