Abstract：BACKGROUND:Recurrent lumbar disc herniation is very common in the clinic. Most patients have adjacent segment degeneration at the same time, and second operation is more difficult than first time. <br> OBJECTIVE:To investigate the more than 6-month fol ow-up results of posterior interbody fusion and pedicle screw fixation in the repair of recurrent lumbar disc herniation. <br> METHODS:Complete fol ow-up data of 40 patients with recurrent lumbar disc herniation, who were treated from January 2010 to January 2012, were retrospectively analyzed. Al secondary surgeries received posterior laminectomy, discectomy, interbody fusion and pedicle screw fixation. Japanese Orthopaedic Association (29 scores) and low back pain Visual Analog Scale were used to assess neurological functions and rational symptoms before and after treatment and during final fol ow-up. Therapeutic effects after treatment were assessed and improvement rate was calculated. <br> RESULTS AND CONCLUSION:40 patients were fol owed up from 6 to 36 months. Japanese Orthopaedic Association scores were significantly improved at 2 months after treatment and during final fol ow-up compared with pre-treatment (P<0.05). Visual Analog Scale scores were significantly improved at 2 months after treatment and during final fol ow-up compared with pre-treatment (P<0.05). These data suggested that first surgery destroys stability of spine, speeds up adjacent degeneration. Posterior interbody fusion and pedicle screw fixation in the repair of recurrent lumbar disc herniation can solve some problems such as complete decompression,stable integration, scar adhesion and oppression, and obtain good repair effects.
