Application of RSS pedicle screw fixation and bone fusion in the treatment of lumbar disc herniation complicated with lumbar instability

Objective To investigate the effect of lumbar disc herniation were treated with RSS pedicle screw fixation and bone fusion and clinical effect of treatment.Methods Seventy-two patients of lumbar disc herniation and lumbar instability were selected from August 2008 to 2013 February in our hospital as the research objects,all the patients according to different operation mode were divided into the observation group and control group,with 36 cases in each group,the control group before 2010 August were treated with nucleus pulposus,processus posterior bone grafting;the observation group after 2010 August were treated with RSS pedicle screw fixation and fusion for treatment,compared the clinical effect of two groups.Results JOA score at the end of the follow-up of two groups was significantly higher than that of before operation,JOA score at the last follow-up,improvement rate and excellent and good rate of JOA,the fusion rate of bone graft in the observation group were higher than the control group,the differences were significant(P 0.05).ODI score at the last follow-up of two groups was significantly lower than preoperative,differences at the last follow-up ODI score between the two groups was significant(P 0.05).Conclusion RSS pedicle screw internal fixation and bone grafting fusion for lumbar disc herniation treatment can make the symptoms improved signif icantly,satisfactory clinical effect.
