Refracture of the cemented vertebrae after percutaneous vertebroplasty: risk factors and imaging findings

Abstract Background To determine the related imaging findings and risk factors to refracture of cemented vertebrae after percutaneous vertebroplasty (PVP) treatment. Methods Patients who were treated with PVP for single vertebral compression fractures (VCFs) met this study’s inclusion criteria retrospectively reviewed from January 2012 2019. The follow-up period was at least 2 years. Forty-eight patients 45 non-refractured included. following variates reviewed: age, sex, fracture location, bone mineral density (BMD), intravertebral cleft (IVC), kyphotic angle (KA), wedge angle, endplate cortical disruption, cement volume, surgical approach, non-PMMA-endplate-contact (NPEC), leakage, other fractures, reduction rate (RR), (RA). Multiple logistic regression modeling used identify independent refracture. Results Refracture found in 48 (51.6%) patients. Four factors, including IVC ( P = 0.005), disruption 0.037), larger RR 0.007), NPEC 0.006) be significant Conclusions or RR, NPEC, have a high PVP.
