What Risk Factors Are Associated With Recurrent Osteoporotic Vertebral Compression Fractures After Percutaneous Vertebral Augmentation? A Meta-analysis.

Background: Osteoporotic vertebral compression fracture (OVCF) has been extensively treated clinically using percutaneous vertebral augmentation (PVA), which includes percutaneous kyphoplasty and percutaneous vertebroplasty. Postoperative refracture is a common complication after PVA, but the associated factors and specific mechanisms behind these fractures are not entirely clear.

Questions/purposes: In a systematic review and meta-analysis, we asked: What factors were associated with increased or decreased odds of refracture after PVA for OVCF?

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines, we conducted a comprehensive search of the Cochrane Library, PubMed, Web of Science, and Embase for the time period from database inception to August 31, 2024 (which also was when we last searched).

[The contrast study between single and double balloon bilateral dilatation of kyphoplasty].

Objective: To contrast single and double balloon-inflated kyphoplasty for vertebral compression fractures (VCFs) and evaluate its clinical efficacy.

Methods: From May 2000 to May 2004, 90 consecutive procedures were performed in 58 patients who suffered from painful vertebral compression fractures, transferring tumour and angioma. Ninety vertebrae were inflated while 62 as A group were double balloon and 28 as B group were single balloon, fracture reduction and bone cement augmentation.
