Abstract
Aim: The purpose of this study was to review a single surgeon’s preliminary experiences with minimally invasive
single lateral position anterior-to-psoas lumbar interbody fusion with multiple techniques of percutaneous pedicle
screws and present perioperative results and complication rates.

Methods: After obtaining Institutional Review Board approval, thirty-five consecutive patients undergoing, in 2018-
2020, single position lateral interbody fusion with posterior fixation after obtaining written informed consent.
Pedicle screw accuracy, screw-related complications, overall and segmental lumbar lordosis, intraoperative data,
perioperative complications, and Visual Analog Pain Scale (VAS) at 6 months follow-up were collected.

Results: One hundred sixty-nine pedicle screws were placed in 35 patients with a 95.3% accuracy rate. 6/7
breaches measured < 2 mm. No complications or reoperations were performed in relation to screw malposition.
Mean preoperative overall lumbar lordosis was 45.6° ± 12.5° (range, 19°-71°), and 50.3° ± 9.6° (range, 25°-67°) at
6 months follow up. Mean preoperative VAS scores were 7.3 ± 1.2 (range, 5-10) and 7.3 ± 1.3 (range, 5-10) for the
back and leg, respectively and at 6 months follow up, 2.6 ± 2.3 (range, 0-7) and 2.6 ± 2.2 (range, 0-7) for the back
and leg, respectively. The mean total operative time was 152.2 ± 54.8 min (range, 80-320 min).
