Results of posterior lumbar interbody fusion in post-laminectomy pain syndrome
摘要
Background: Patients who were diagnosed with failed back surgery syndrome (FBSS) underwent posterior lumbar interbody fusion (PLIF) with instrumentation at our hospital. Purpose: The aim of this study was to analyze the clinical and radiologic outcomes of PLIF for post-laminectomy pain syndrome and determine whether any single operation can be used to overcome most of these complications. Methods: The surgical technique consisted of wide decompression with further laminectomy over the ongoing fusion level, nearly total discectomy, end-plate preparation, bone graft packing, insertion of a dual intervertebral spacer, and rigid pedicle screw instrumentation. Results: The mean visual analog scale (VAS) pain score improved from 8.5 preoperatively to 1.9 at the final follow-up. The mean Japanese Orthopaedic Association (JOA) score improved from 9.3 preoperatively to 23.1 at the final follow-up (p ＜ 0.001). The mean recovery rate at the final follow-up was 70.1% (range, 21.0-94.1%). Complications were seen because of perioperative dural tears in six cases, but there were no cases of nerve root injury. A satisfactory result was achieved in 79.7% of our patients, while the overall fusion rate was 88.7%. Conclusion: According to the results of our series, we believe that PLIF can be a reasonable and effective procedure for post-laminectomy pain syndrome with different surgically correctable structural causes.
