Abstract

Objectives:To evaluate the accuracy of the transpedestal screw-in lumbar spondylolisthesis using the O-arm assisted PLIF/TLIF method. Methods: This is a cross-sectional study conducted on 47 patients diagnosed with lumbar spondylolisthesis, surgically treated during the study period (1/2018-1/2019) at the Department of Orthopedic Trauma and Trauma Spine - Bach Mai Hospital. Results: In 47 study subjects, more than half of the patients (53.19%) suffered a leg pain threshold of more than 5 points. The total number of screws to be captured is 204 screws. There are 40 patients with 1-stage lumbar spondylolisthesis corresponding to 160 screws and 6 patients with 2-stage lumbar spondylolisthesis corresponding to 36 screws. In addition, there is a 3-stage surgical object corresponding to the number of screws and 8 screws. According to the assessment of the accuracy of screws that have been captured in surgery according to the standards of Gertzbeinn - Robbins, we have the precision of group A is 95.05%, group B is 4.95%. Each level of sliding is placed with 1 artificial graft, and there are 55 synthetic grafts placed in 47 patients. 90.9 % of the pieces met the excellent standard, and 9.1% of the samples had a good position. Conclusion: The control study has shown that using the PLIF/TLIF method with O-arm supports the high accuracy of squeezed screws.
