Objective To assess the correlation of newly fracture and spinal sagittal parameters.Methods From March 2011 to December 2014,80 patients of osteoporosis vertebral compression fracture treated by PVP as observation group were studied.The whole-spine anteroposterior view and lateral view X-Ray Photographes of the patients were taken,the sagittal parameters such as Pelvic index(PI),sacral slope(SS),pelvic tilt(PT),thoracic kyphotic angle(TK),lumbar lordotic angle(LL),the C7/SFD ratio were recorded.The whole cases were divided into two groups according to the presence of new fracture or not after the last followup of one year,the index of two groups were compared,and the risk factors of newly vertebral compression fractures were analysed.Results There were no statistically significant difference in gender,age,body mass index,BMD,PI,TK,LL between the two treated groups(P0.05);there were statistically significant difference in SS,PT and the C7/SFD between the new vertebral fracture group and the control group(P0.05).The analytic results of Logistic regression model showed that the smaller SS,larger TK and C7/SFD were risk factors of newly vertebral compression fractures.Conclusion The newly occurred vertebral compression fractures,after the primary treatment of PVP,are associated with changed spinal sagittal parameters.
