Abstract: Objective：To observe the therapeutic effect of vertebroplasty balloon dilatation combined with acupuncture on patients with osteoporotic lumbar spine fracture who received PKP.Methods：Retrospective analysis was performed on 47 patients with osteoporotic lumbar spine fracture treated by PKP,and they were divided into acupuncture group(23 cases) and separate PKP group(24 cases) according to whether combined acupuncture treatment was available.After the PKP operation,the acupuncture group patients were given acupuncture therapy，Yaoshu point, Pishu point, Weizhong point and Ashi point were selected;Patients in the PKP group only received PKP treatment,and no acupuncture therapy was performed postoperatively.Visual analogue scale(VAS),functional impairment index(ODI),and kyphosis angle(KA) were used to evaluate the clinical efficacy.Results：All patients were successfully followed up for 1217 months,with an average followup time of(12.73±3.17) months.There was statistically significant differences in preoperative and postoperative KA angle between the two groups(P<0.05),KA angle was not significantly different between the two groups at each followup time point after operation(P>0.05).VAS and ODI were significantly different between the two groups after surgery and before surgery(P<0.05).Compared with VAS scores from 1 month to 6 months after surgery,the acupuncture group was significantly better than the PKP group alone(P<0.05).During the followup 6 months after surgery,there was no statistically significant difference in VAS scores between the two groups(P>0.05).ODI of the acupuncture group was significantly better than that of the PKP group alone(P<0.05).Conclusion：Acupuncture combined with PKP can achieve more satisfactory clinical efficacy than PKP alone in the treatment of lumbar osteoporosis fracture.
