Retrospectively Analysis of 240 Cases of Failed Back Surgery Syndrome

Abstract：Objective To analyze the cause and the method of primary operation of failed back surgery syndrome(FB-SS). Methods Patients with failed back surgery syndrome during January 2003 to December 2013 in the Department of ortho-pedic surgery of my Hospital were retrospectively enrolled. According to the different primary diagnosis before the primary oper-ation,patients were divided into three groups. Group one received 182 patients whose primary diagnosis are lumbar disc hernia-tion. Group two received 31 patients whose primary diagnosis are lumbar spinal stenosis. Group three received 27 patients whose primary diagnosis are lumbar spondylolisthesis. We reviewed all patients' medical records,including sex,age,course of the recurrent symptom,the method of primary operation,the location of the first surgical segment and diagnosis. We analyzed the causes of FBSS and the relationship with method of primary operation. Results 240 were enrolled in this study including 136 males and 104 females. The the most frequent causes of three groups were recurrent lumbar disc herniation,lumbar spinal stenosis and instrumentation failure,respectively. The most failed methods of primary operation of three groups were fenestration laminectomy and discectomy,laminectomy,internal fixation and posteriolateral fusion,respectively. Conclusion The causes of FBSS are complex,including recurrent lumbar disc herniation accounting,lumbar spinal stenosis,complications,adjacent seg-ment disease,the failure of instrumentation. Using right surgical method may can reduce the incidence of FBSS.
