Objective： To explore the clinical results of the operation of posterior decompression, vertebral interbody fusion with cage and transpedicular screw fixation for the treatment of recurrent lumbar disc herniation. Methods： 51 cases treated with the operation of posterior decompression, vertebral interbody fusion with cage and transpedicular screw fixation were reviewed retrospectively. The results were evaluated with Japanese Orthopedic Association score. Results： The average operative time was 160 minutes and the average blood volumn was 580 ml. 51 cases were followed for an averge period of 3 years. There was a significant increase of JOA score in the latest follow-up（P〈0.05 ）.88% of patients＇ clinical results were excellent or good. Conclusion： Posterior decompression, vertebral interbody fusion with cage and transpedicular screw fixation for recurrent lumbar disc herniation achieved good clinical results.
