Correlation analysis between different preoperative diagnoses and superior facet joint violation in posterior lumbar interbody fusion
Objective To compare the incidence of superior facet joint violation in patients with different preoperative diagnoses in posterior lumbar interbody fusion.Methods The clinical data of 320 patients who underwent posterior lumbar interbody fusion from January 2018 to December 2021 in our hospital were retrospectively analyzed,and the preoperative diagnoses were including the lumbar disc herniation/lumbar spinal canal stenosis,degenerative lumbar spondylolisthesis,and isthmic lumbar spondylolisthesis.The superior facet joint violation was graded based on the postoperative lumbar CT,the incidences of superior facet joint intrusion of patients with different preoperative diagnosis were compared,and the correlations between relevant parameters(including the apical vertebrae of fixation segments,facet joint angle,depth of lamina,introversion angle of pedicle screw,axial diameter of facet joint,and slippage length of vertebrae)with superior facet joint violation and preoperative diagnoses were investigated.Results The incidence of superior facet joint violation in the patients with isthmic lumbar spondylolisthesis(57.4%)was higher than that in the patients with lumbar disc herniation/lumbar spinal canal stenosis(41.2%)and degenerative lumbar spondylolisthesis(35.9%),with statistically significant differences(P<0.05).The apical vertebrae of fixation segments,facet joint angle,axial diameter of facet joint and introversion angle of pedicle screw were related with the occurrence of superior facet joint violation(P<0.05).There were statistically significant differences in the facet joint angle,axial diameter of facet joint and apical vertebrae of fixation segments among patients with different preoperative diagnoses(P<0.05).Conclusion Patients with isthmiclumbar spondylolisthesis are more likely to occur superior facet joint violation than patients with lumbar disc herniation/lumbar spinal canal stenosis and degenerative lumbar spondylolisthesis.
