Comparison of the efficacy of posterior lumbar interbody fusion and transforaminal lumbar interbody fusion in the treatment of double-level lumbar spondylolisthesis combined with spinal stenosis: a retrospective comparative study
Retrospective comparative study compares clinical outcomes of PLIF and TLIF surgeries in lumbar conditions, suggesting both methods are effective.
Key Points
The study aims to compare the clinical and radiographic outcomes of PLIF and TLIF in treating double-level lumbar spondylolisthesis and spinal stenosis.
Retrospective comparative study including 44 patients who underwent surgery between April 2013 and August 2021.
Patients were divided into PLIF and TLIF groups for outcome evaluation.
Clinical outcomes were measured using VAS and ODI scores preoperatively and at multiple postoperative intervals.
Both PLIF and TLIF groups showed significant improvement in VAS scores and ODI at all follow-up points (P < 0.05).
Radiographic assessments indicated significant improvements in sagittal alignment and vertebral slippage (P < 0.05).
No significant clinical differences were found between PLIF and TLIF groups (P > 0.05).
