Unilateral biportal endoscopy (UBE) is a new spinal minimally invasive technique improved for the treatment of lumbar spondylolisthesis (LSP). The present study aims to establish a multicenter, large sample, randomized controlled study to explore the technical advantages and surgical indications of this new technique in the treatment of LSP by comparing with the classical minimally invasive posterior spinal interbody fusion; to compare the postoperative clinical and imaging results and analyze the surgical complications and preventive measures.
