ABSTRACT
Objective To investigate the clinic technique and effect of treating lumbar disc herniation (LDH) with decompressor and ozone injection combined lumbar traction after surgery.Methods 110 contained LDH patients were randomly divided into two group:decompressor and ozone group,decompressor and ozone combined lumbar traction after surgery group.Under the guidance of CT,fifty-five patients in group A were treated by disc decompression with Decompressor through poster olateral approach,then ozone was injected into the lumbar disc or out side the lumbar disc,and the other fifty-five patients in group B were treated by lumbar traction after surgery that disc decompression and ozone injection same as the group A in once a day and one week of treatment.The theraputic effect was evaluated by comparing VAS,effective rate of therapy before and after treatment.Results The VAS score of two groups at 1,3,7 days between pre-and post-treatment had singificantly different(t =2.159,2.163,2.169,2.167,2.173,2.192,all P ＜0.05).110 case were followed up after 6 and 12 months,The good-excellent rate of therapy in B group 12 months were better than those of A group (x2 =74.23,75.11,all P ＜ 0.05).Conclusion Decompressor combined ozone injection and lumbar traction after surgery is an effective menthod for treatment of the central type mbar disc herniation.
