title: Postoperative Functional Evaluation of Percutaneous Vertebroplasty Compared With Percutaneous Kyphoplasty for Vertebral Compression Fractures.
abstract: Both percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) have shown their superiorities in the treatment of vertebral compression fractures (VCFs), yet, few studies have compared their postoperative functional outcomes in patients with VCFs; the authors therefore conducted this meta-analysis to explore the postoperative functional recovery efficacies of PVP and PKP in the treatment of VCFs. Computerized bibliographic databases were applied to identify relevant articles comparing the therapeutic effect of PVP and PKP in the treatment of VCFs. Standardized mean difference and its 95% confidence interval were calculated. Statistical analyses were conducted with the STATA statistical software. Postoperative Oswestry Disability Index investigation outcomes revealed a significant difference between the PVP group and PKP group. Subgroup analysis by the 8 dimensions of the SF-36 health survey presented a statistical significance in general health between the PVP group and PKP group. The application of PKP has the superiority in postoperative functional recovery of VCFs as compared with PVP, especially in efficaciously extending kyphosis angle, improving vertebral body height and decreasing complication rate.
