The clinical efficacy of percutaneous vertebroplasty augmentation for the nonmidline pain of the osteoporotic vertebral compression fracture

Objective To assess the effect of percutaneous vertebral augmentation for the relief of pain caused by the osteoporotic vertebral compression fracture(OVCF).Methods 90 patients with OVCF were performed the percutaneous vertebroplasty(PVP) or kyphoplasty(PKP).The prevalence of pain,visual analog scales (VAS) of patients before and different time points after operation were observed.Results In 90 cases,44 cases with OVCF were suffered from nonmidline pain,among which 37 cases (48.05％) in the PVP group and 13 cases (53.85％) in the PKP group,the incidence of pain between the two group was not statistically significant(x2 =0.149,P =0.699).There were 20 cases with pain in sacrococcygeal area,8 cases below the xiphoid,6 cases in lateral thorax and 2 cases in chest in the PVP group,and 5 cases in sacrococcygeal area,1 case respectively below the xiphoid and in chest in the PKP group; the VAS score between the two groups before surgery (t =0.22,P =0.825),postoperative instant (t =0.66,P =0.508) and the last follow-up (t =1.13,P =0.263) were not statistically significant; the VAS scores of both groups had significant differences at different time points (FPVP =35.65,PPVP ＜ 0.01,FPKP =30.44,PPKP ＜ 0.01) ;the pain relief was the most significant 72h after operation(t =33.43,P ＜ 0.001).Conclusion The pain is common clinical manifestations in patients with OVCF,the percutaneous vertebral augmentation can effectively alleviate the nonmidline pain caused by the OVCF.
