Clinical Study on the Therapeutic Efficacy of Biportal Endoscopic Decompression Spine Surgery and Lumbar Decompression Fusion Surgery in the Treatment of Degenerative Lumbar Spondylolisthesis

This study aims to systematically evaluate the therapeutic efficacy of dual-channel endoscopic spinal decompression versus lumbar decompression with fusion for degenerative lumbar spondylolisthesis. Patients undergoing either procedure will undergo detailed preoperative and postoperative follow-up to compare outcomes between the two techniques, specifically assessing postoperative pain relief, neurological improvement, and the incidence of surgical complications.
