The clinical study of lumber spondylolisthesis by pedicle screw and interbody fusion cage

Objective To detect the efficacy of lumber spondylolisthesis by pedicle screw and interbody fusion cage,for accumulating clinical experience and directing clinical work.Methods 80 cases with lumber spondylolisthesis were divided into observation group（40 cases）and control group（40 cases）.The control group was treated by nail-stick system and intertransverse process autograft fusion.The observation group was treated by pedicle screw and interbody fusion cage.The efficacy were observed in the two groups.Results The efficacy was obviously higher in the observation group than in the control group.Conclusion The satisfied efficacy is found in observation group.The treatment of pdeicle screw and interbody fusion cage is worthy be recommended in patients with lumber spondylolisthesis.
