Abstract

Objectives: To assess the results of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for lumbar spondylolisthesis. Subjects and methods: A descriptive study of 51 cases of patients with single level lumbar spondylolisthesis received MIS-TLIF at the Spine Surgery Department, Viet Duc university Hospital from January 2019 to December 2020. Results: 51 patients (11 men, 40 women), mean age was 47,9 ± 12,9 years (from 15 to 72). Long-term outcome after surgery was assessed according to MacNab criteria at 12 months after surgery 44/51 patients re-examined (86,3%): Excellent: 28 (63,6%), good: 14 (31, 8%), fair: 2 (4,6%), poor: 0 (0,0%). Evaluation of clinical symptoms improvement after surgery: VAS (Visual Analogue Scale) back pain improved from 6,22 ± 1,06 to 1,89 ± 1,50, VAS leg pain improved from 5,90 ± 1,40 to 1,25 ± 1,50, ODI (Oswestry Disability Index) improved from 49,41 ± 8,00 to 15,18 ± 11,58. Evaluation fusion according to Bridwell: the rate of bone healing was 97,8%. Intraoperative complications: Nerve roots injury in 2 cases (3,9%). Conclusion: MIS-TLIF is a safe and effective procedure in the treatment of single level lumbar spondylolisthesis.
