Our study focuses on single-level lumbar spondylolisthesis patients who had minimally invasive surgery treatment with percutaneous screws and intervertebral fusion cage transforaminal system for 5 years (1/2019 - 12/2023) at Hanoi Medical University Hospital. The study was conducted on 110 patients that matched the criteria, in which 88.1% had grade 1 spondylolisthesis and 11.9% had grade 2 spondylolisthesis. The average age was 48.53 ± 8.13 years old, female/male ratio 1.62; the common cause was par defect at 29.1% and degenerative at 70.9%. The most common level was L4L5 at 57.27%. 100% had back pain with VAS average 6.7 ± 3.2, radiculopathy leg pain got 95.5% with VAS average 6.5 ± 3.8. ODI pre-operation was 43.5 ± 14%, the average time of surgery was 115 ± 23 minutes, the average blood loss was 150 ± 43ml; Complication: 1 case with small epidural tear recovered by only placement of muscle and hemostatic material, 2 cases K-wire passing through the anterior border of the vertebral during tap driver to pedicle; Hospital stay average time was 4.2 ± 2.6 days; the postoperative average time for return to walking was 2.1 ± 0.8 days. Results after 9 months postoperative follow-up: Very good 35.5%, Good 40.9%, Medium 22.7%, Bad 0.9%. Results after 24 months postoperative: Very good 57.7%: Good 21.7%, Medium 20.6%. Compared to traditional procedures with open spinal fixation and interbody fusion, minimally invasive surgery helps reduce blood loss, shorten hospital stay, and early recovery for patients.
