Clinical Study of Bilateral Decompression With Interbody Fusion for Spondylolisthesis

Not Applicable

• Conditions: Lumbar Spondylolisthesis

• Registration Number: NCT02972190
• Lead Sponsor: Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University

Brief Summary

Laminectomy with PLIF has been shown to achieve satisfactory clinical outcomes, but it leads to potential adverse consequences associated with extensive disruption of posterior bony and soft-tissue structures. The investigators plan to compare the clinical and radiographic outcomes of bilateral decompression with transforaminal lumbar interbody fusion and laminectomy with posterior lumbar interbody fusion in the treatment of degenerative spondylolisthesis.
