RESUMO
<p><b>OBJECTIVE</b>To identify risk factors associated with patients suffered multiple level osteoporosis vertebral compression fractures(OVCFs).</p><p><b>METHODS</b>From March 2011 to March 2015, 199 patients suffered osteoporotic were classified into multiple level OVCFs group and single level OVCF group. Multivariate logistic regression analysis were performed to identify risks factors associated with multiple level OVCFs.</p><p><b>RESULTS</b>All the patients underwent OVCF, including 71 multiple level OVCFs and 128 single level OVCF. There were no differences in the age, gender, BMI, hypertension and diabetes between two groups. While multiple level OVCFs were associated with spinal deformity index SDI[(2<=SDI<4, OR=2.587, 95% CI(1.148, 5.828);SDI>=-4, OR=7.775, 95% CI(3.272, 18.478)], BMD[(T<-4.5SD, OR=2.608, 95% CI(1.038, 6.551)].</p><p><b>CONCLUSIONS</b>SDI and BMD might be the risk factors for multiple level OVCFs.</p>
