Abstract

Objectives: To evaluate the surgical outcomes and restoration of spinopelvic alignment in patients with double-level lumbar spondylolisthesis treated via percutaneous pedicle screws and posterior lumbar interbody fusion. Methods: A combined retrospective and prospective study was conducted on 34 patients (mean age 54.2 ± 11.5 years; 79.4% female) who underwent surgery at Hanoi Medical University Hospital between 2020 and 2025. Data on clinical symptoms, functional status (ODI), pain scores (VAS for back and leg), length of hospital stay, spinopelvic parameters (PI–LL mismatch, PT, SS), fusion rates, and complications were collected preoperatively and at 6 months postoperatively. Statistical analysis was performed using paired t-tests (p < 0.05 significance). Results: The average hospital stay was 10.9 ± 3.6 days. Mean back VAS decreased from 7.24 ± 0.61 to 2.00 ± 0.65 (p < 0.05), and leg VAS from 7.26 ± 0.62 to 1.85 ± 0.50 (p < 0.05). ODI improved from 54.2 ± 11.6% to 15.4 ± 9.2% (p < 0.05). PI–LL mismatch reduced from 24.6 ± 11.0° to 18.6 ± 9.4° (p < 0.001), with 6/34 patients (17.6%) achieving PI–LL ≤ 10° postoperatively. Conclusion: Percutaneous TLIF achieves significant pain relief and functional improvement, effectively restores spinopelvic alignment, shortens hospital stay, and minimizes complications in double-level lumbar spondylolisthesis.
