ABSTRACT

Objective To explore the efficacy of percutaneous nucleus pulposus atherectomy combined with ozone injection in treatment of lumbar disc herniation.Methods A total of 60 patients with lumbar disc herniation were randomly divided into 3 groups20 patients were treated by ozone injection (group A),20 patients were treated by percutaneous atherectomy (group B),20 patients were treated by percutaneous atherectomy combined with ozone injection (group C).The changes of visual analogue scale (VAS) and clinical effects in three groups pre-and 1 week,1 month and 3 month postoperation were compared.Intraoperative and postoperative complications were analyzed.Results The VAS of postoperation in three groups were significantly lower than those of preoperation (all P＜0.017).The short term and long term VAS of group C were lower than those of group A and group B (all P＜0.017).But there was no statistically significant difference among three groups of recent and long-term excellent rates (all P＞0.017).related complications were mainly waist pain,lower limb soreness and pain.Conclusion Percutaneous nucleus pulposus atherectomy combined with ozone injection is a safe and effective method,which can improve the curative effect of operation.
