Objective:To investigate the technique of single-segment fixation with stabilizing bone graft to the defect and its value in treating the lumbar vertebral spondylolysis. Method:Forty-six patients were treated with pedical screw,lamina hook,bone-planting in the isthmic spondylolysis,with follow-up after operation ,and investigated the union of spondylolysis the improvment of symptom and the ability recovery of work and motion.Result:After mean 16 months follow-up, 43 patients with low back pain or radicular pain experience significantly relieved,the spondylolysis union and the recovery of ability was good ,the excellent-good rate was 93.5%.There were no complications of infection,breakage of internal fixation and the nerve root injury. Conclusion:The method used for direct repair of the defect of the pars interarticularis in these patients is proved to be simple and effective.
