Abstract: Objective The study aimed to identify risk factors of lumbar disc herniation in patients after decompression,and provide theoretical basis for postoperaive rehabilitation.Methods A told of 169 patients with lumbar spinal stenosis underwent bilateral partial laminectomy were included in the study,24 patients in herniation group,and 145 patients without develop postoperative acute sciatica as a control group.The radiographic variables were measured.The threshold of risk factors was evaluated by multiple logistics analysis and receiver operating characteristic curve(ROC) analysis.Results The results revealed that preoperative retrolisthesis during extension was the independent risk factor for lumbar disc herniation(1.24,95％CI[1.07～1.43];P<0.01).The area under the curve(AUC) was 0.801,and the cutoff value was 6.89％.Conclusion The preoperative retrolisthesis was the risk factor of lumbar disc herniation.
