Objective To observe the effect of threaded titanium cage and transpedical screw for the treatment of lumbar spondylolisthesis. Methods Eighteen patients with lumbar spondylolisthesis were adopted in this study. Among them, there were 8 males and 10 females, aged from 43 to 62 years old .Roentgenogram showed that there were 6 cases of Ⅰ° spondylolisthesis, 11 cases of Ⅱ° and 1 case of Ⅲ°. All patients were treated with cages for intervertebral fusion after total laminectomy and pedicle screws for the reduction. Results The cases were followed up from 6 to 12 months with an average of 11 months. The clinical results were excellent in 13 cases and good in 5 cases. All patients achieved successful fusion and bony union . There were no pedicle screw loosening or broken or peripheral nerve dysfunction in this series. Conclusion This method has been proved to be an effective and reliable procedure for treatment of lumbar spondylolithesis. It produces a high fusion rate and clinical success.
