The rate of adjustment for guide wires under the assistance of electromagnetic navigation was 1.78%, and the frequency of X-ray exposure was 8.27 ± 1.83. According to postoperative CT scans and 3D reconstructions, the excellent and good rate of pedicle screws was 96.4%. The mean age of the patients was 56.1 ± 9.26 years, with a female/male ratio of 25:17. The mean follow-up for 42 patients was 11.9 ± 3.1 months. The rate of adjustment for guide wires, frequency of X-ray exposure, operative time, accuracy of pedicle screw location, and clinical outcomes were recorded. The procedures were assisted under electromagnetic navigation. Clinical information from 42 patients who had received Endo-TLIF with percutaneous pedicle screw fixation from May 2019 to November 2020 was analyzed retrospectively. This retrospective study explored the effects of electromagnetic navigation on improving Endo-TLIF with percutaneous pedicle screw fixation. However, repeated radiation exposure from X-rays and the steep learning curve remain to be improved. Uniportal full endoscopic posterolateral transforaminal lumbar interbody fusion (Endo-TLIF) with percutaneous pedicle screw fixation is a promising, minimally invasive method for the treatment of lumbar spondylolisthesis.
