Abstract:
Objective To investigate the curative effect for lumbar spondylolisthesis by posterior lumbar intervertebral compression bone graft fusion and pedicle screw internal fixation.Method All 39 cases with lumbar spondylolisthesis accepted treatment during January 2003 to October 2007.There were cataplasia spondylolisthesis in 14 cases and isthmic spondylolisthesis in 25 cases.Twenty-two cases had spondylolisthesis in L4 and 17 cases had spondylolisthesis in L5.According to Meyerding grading,11 patients were classified as degree Ⅰ lesion.27 patients as degree Ⅱ lesion and 1 patient as degree Ⅲ lesion.By the help of X-ray machine,pedicle screw Was embedded in the vertebral spondylolisthesis and it Was lower vertebra.Laminectomy decompress was administered in vertebral spondylolisthesis and hold-down bars was placed to open intervertebral space.Then restored the vertebral spondylolisthesis and fixed it temporary.Next,intervertebral compression bone graft fusion was finished and was adjusted.Results Follow-up period was 5 months to 4 years.Clinical outcomes were measured with Prolo evaluation scale,35 cases were cured,4 cases were good effect.Conclusions This operation has been found to be asafe,rapid and effective method for lumbar spondylolisthesis and it produces a high fusion rate and lower expense.
