The clinical effect analysis of the treatment of degenerative lumbar spondylolisthesis with pedicle screw system

Objective To investigate the method and therapeutic effect of degenerative spondylolisthesis.Methods 24 cases of degenerative spondylolisthesis were treated with posterior entire vertebral lamina decompression, pedicle screws instrumentation and bone graft fusion.Results All the patients were followed up from 7 to 28 months.The clinical excellent rate was 87.5%. The rate of successful reduction of slipping vertelrral body was 95.2%,The fusion rate was 100% for interbody Cage fusion and 89.5% for PLF.No pedicle screw breakge and Cage slipping was found.Conclusion Appling the above surgery way,it can relieve nervous compression,correct spinal deformity and fix distabilzed spine. So it can restore the nervous function effectively, maintain the spinal normal shape and mechanics stability. complete the purpose of the therapy for the lumbar spondylolisthesis.
