    Abstract:
    BACKGROUND Percutaneous vertebral augmentation is the mainstream treatment of osteoporotic vertebral compression fracture (OVCF). New vertebral compression fracture (NVCF) after percutaneous vertebral augmentation may be an issue that cannot be ignored. Nevertheless, the risk factors for NVCF are still uncertain. This research aimed to study the risk factors for NVCF after percutaneous vertebral augmentation. MATERIAL AND METHODS All patients who underwent percutaneous vertebral augmentation for OVCF from January 2019 to December 2020 were enrolled in the study. These patients were divided into NVCF and control groups according to whether they had NVCF. The covariates including sex, age, BMI, diabetes, hypertension, smoking, alcohol, fracture level, surgical method, cement leakage, cement volume, preoperative anterior vertebral height ratio, and Hounsfield unit (HU) value were reviewed. Univariate and multivariate analyses were performed to identify risk factors. RESULTS A total of 279 patients were included in this study, of which 47 had NVCF after percutaneous vertebral augmentation. Univariate analysis demonstrated that there were significant differences in age (OR=1.040, 95% CI=1.003-1.078, P=0.033), BMI (OR=0.844, 95% CI=0.758-0.939, P=0.002) and HU value (OR=0.945, 95% CI=0.929-0.962, P<0.001) between the 2 groups. Multivariate regression analysis revealed that HU value (OR=0.942, 95% CI=0.924-0.960, P<0.001) were independent risk factor for NVCF after percutaneous vertebral augmentation. CONCLUSIONS Hounsfield unit value was an independent risk factor for new vertebral compression fracture after percutaneous vertebral augmentation, whereas age and BMI were not.
