【Abstract】 Objective: For the treatment of spondylolisthesis,we designed a single segmental reduction fixation system with the following advantages:(1)less injury;(2)satisfactory reduction;(3)stable fixation.Method:20 cases of lumbar spondylolisthesis were selected for operation with this system.The mean follow up time was 2 years and 10 months.The clinical and radiological results were evaluated.Result:The preoperative slipping was grade Ⅱ in 15 cases,grade Ⅲ in 3 cases.The mean correction rate was 91%.Partial correction loss occurred in 6 cases six months after operation.Implant breakage occurred in 2 cases.18 cases have good results.2 cases have fair results.No neurological complication occurred.Conclusion:The single segmental reduction fixation system is a good method with less injury and satisfactory result on the treatment of spondylolisthesis.Long term result of reduction depends on good bone grafting and suitable lumbar protection after operation.更多还原
