OBJECTIVES: The study aimed to compare the efficacy and safety of percutaneous kyphoplasty (PKP) and vertebral body stenting (VBS) in the treatment of osteoporotic vertebral compression fractures (OVCFs) and evaluate the clinical efficacy, Cobb angle correction, and cement leakage associated with both methods for OVCFs. PATIENTS AND METHODS: A systematic search was conducted in PubMed, EMBASE, Cochrane Library, Medline, China National Knowledge, and Wanfang Data for clinical studies comparing VBS with PKP for OVCF up to May 2023. The meta-analysis was performed using Review Manager 5.3, with a focus on evaluating clinical and radiologic outcomes. RESULTS: A total of eight eligible clinical studies were included in this meta-analysis. In terms of clinical outcomes, VBS was found to have a longer surgical time compared to PKP (standard mean difference [SMD]=1.06 min; 95% confidence interval [CI]: 0.20, 1.92; p=0.02). However, VBS demonstrated comparable blood loss to PKP (SMD =0.00 mL; 95% CI: -0.45, 0.45; p=0.99). Additionally, VBS showed slight superiority in alleviating back pain as measured by the Visual Analog Scale (VAS) (SMD=-0.38; 95% CI: -0.63, -0.12; p=0.004), as well as in improving functional disability based on the Oswestry Disability Index (ODI) (SMD= -0.28; 95% CI: -0.54, -0.03; p=0.03). Radiographically, VBS achieved better Cobb angle correction compared to PKP (SMD= -1.00; 95% CI: -1.48, -0.51; p<0.0001), while there was no significant difference in cement leak...
