[Abstract] Objective To investigate the correlative factors of adjacent vertebral fractures after percutaneous vertebroplasty（PVP） for osteoporotic vertebral compression fractures（OVCFs）at the Thoracolumbar Junction. Methods 90 patients of single Percutaneous Vertebroplasty at the Thoracolumbar Junction (T11, T12, L1, L2) were analyzed retrospectively and the follow-up period was about 12~36 months. Record all the adjacent vertebral compression fractures. We evaluated patient age，weight，sex, amount of injected cement, intradiskal cement leak, initial wedge angle of the compression fracture and percentage of height restoration of the vertebral body. Inthis report, we surveyed the possible risk factors for new symptomatic vertebral compression fractures.Results 22 of the 90 patients had new adjacent vertebral compression fractures after PVP, with the total rate of 24.44%. The cement leakage rate of group A is 33.33%,and group B is13.43%, P value is 0.039（Pgt;0.05）,which show cement leakage is a risk factor for new adjacent vertebral compression fractures The restoration rate of anterior vertebral height in group A is 14.448plusmn;2.166, and group B is 9.149plusmn;0.909,the P value of t-test is 0.01（Pgt;0.05）,these data were considered statistically significant.Conclusion Adjacent vertebral fractures after PVP for OVCFs may be as
