摘要
目的骨质疏松性椎体压缩骨折经椎体成形治疗后新发骨折与脊柱矢状位参数的关系。方法选择2011年3月至2014年12月于该院脊柱外科行椎体成形术的胸腰椎骨质疏松性椎体压缩骨折患者80例,作为观察组。椎体成形术后摄脊柱全长正侧位X线片,记录患者的矢状位参数:骨盆指数(PI)、骶骨斜坡(SS)、骨盆倾斜角(PT),胸椎后凸角(TK)、腰椎前凸角(LL)、C7矢状位比值(C7/SFD),随访一年后,根据有无新发骨折分为两组,比较两组资料的指标差异,并分析椎体再次骨折的危险因素。结果随访一年后,新发椎体骨折12例;两组间性别、年龄、BMI、BMD、PI、TK、LL比较,差异均无统计学意义(P>0.05),组间SS、PT、C7/SFD相比较,差异有统计学意义(P<0.05);Logistic回归模型进行分析,SS、TK和C7/SFD是新发椎体骨折的危险因素。结论骨质疏松性椎体压缩骨折经过椎体成形术治疗后新发椎体压缩骨折与脊柱矢状位序列改变有关。
Objective To assess the correlation of newly fracture and spinal sagittalparameters. Methods From March 2011 to December 2014,80 patients of osteoporosis vertebral compression fracture treated by PVP as observation group werestudied. 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 follow- up 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,P1,TK,LL between the two trea- ted groups （P〈0.05） ;there were statistically significant difference in SS,PT and the CT/SFD between the new vertebral fracture l group and the control group （P〈0.05）. The analytic results of Logistic regression model showed that the smaller SS, larger TK and CT/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.
