Objective: To report the results obtained according to the position of an anterior TLIF device. Materials and Methods: Multicenter, observational, analytical, cross-sectional, retrospective recovery study. We evaluated the pre and post-operative spinopelvic parameters of the spinograms of 20 patients who underwent surgery between September 2019 and August 2021. Patients who had undergone lumbar arthrodesis with an anterior TLIF implant were included, whereas patients without a pre or post-surgical spinogram and more than one device were excluded. Results: The mean monosegmental lordosis was 13.33° preoperatively and 18.81° postoperatively (p <0.001). The mean monosegmental lordosis was 7.32°, 2.95°, and 6.24° for positions I, II, and III, respectively. The mean disc height was 6.22 mm for the preoperative period and 11.06 mm for the postoperative period (p >0.001).Conclusion: We found encouraging results on the placement of this type of device and its relationship with segmental lordosis, understanding the importance of its placement at the anterior end of the disc space.
