Effect observation of different bone graft materials in the treatment of lumbar spondylolisthesis

Objective To explore the application effect of different bone graft materials in the treatment of lumbar spondylolisthesis. Methods 96 cases with lumbar spondylolisthesis in our hospital were selected and divided into three groups according to different materials of the cervical interbody fusion,32 cases in each group.Group A was treated with host bone,group B was treated with allograft bone and group C was treated with BMP artificial synthetic bone.The height of intervertebral space,bone graft fusion rate and nerve function of three groups was compared respectively. Results The height of intervertebral space in group A and group C after 6,12 months was higher than that in group B,with significant difference(P0.05).The fusion rates of bone graft,the total effective rate of the improvement of the nerve function in group A and group C after 12 months was higher than that in group B,with significant difference(P0.05).There was no significant difference in the fusion rates of bone graft,the total effective rate of the improvement of the nerve function between group A and group C(P 0.05). Conclusion Artificial bone and host bone in the treatment of lumbar spondylolisthesis has the equivalent therapeutic effect,it is worthy of clinical promotion and application.
