Comparison of biportal endoscopic vs minimally invasive transforaminal lumbar interbody fusion for single-level low-grade lumbar spondylolisthesis: A retrospective cohort study

Figure 3 A 54-year-old female patient with L4 lumbar spondylolisthesis (Meyerding grade I) from the biportal endoscopic transforaminal lumbar interbody fusion group. A and B: Preoperative anteroposterior and lateral radiographs; C and D: Postoperative 3-month anteroposterior and lateral radiographs; E and F: Anteroposterior and lateral X-ray at the final follow-up after operation showed good reduction; G and H: Computed tomography scans at the final follow-up after operation showed that the reconstruction of the trabeculae between the upper and lower endplates, and the position of the Cage was good.
