摘要/Abstract

摘要： 目的定量观测经皮弯角椎体成形术（percutaneous curved vertebroplasty, PCVP）后骨水泥分布特征。方法测量并比较PCVP术后正位平片上骨水泥在椎体两侧的分布面积;建立术后椎体及骨水泥的三维模型,以椎体正中矢状面及轴面分割骨水泥模型,分别计算穿刺侧及对侧,上方及下方的骨水泥体积及占比,并进行统计学分析。结果穿刺侧骨水泥面积2.19~6.08 cm²,平均(3.87±1.00) cm²;对侧骨水泥面积1.71~6.21cm²,平均(3.18±1.18) cm²,两侧差异有统计学意义(P<0.05)。穿刺侧骨水泥体积平均(4 821.7±1 151.8) mm³,占骨水泥总体积(62.2±10.4) %,占椎体体积(16.9±3.1) %;对侧骨水泥体积平均(2 982.5±1 207.9) mm³,占骨水泥总体积(37.8±10.4) %,占椎体体积(10.8±4.2) %,两侧相比均有统计学意义(P<0.05)。上方骨水泥体积平均 (4 242.9±1 165.8) mm³,占骨水泥总体积(55.2±15.1) %,占椎体体积(14.9±3.5) %;下方骨水泥体积平均(3 574.3±1 539.7) mm³,占骨水泥总体积(44.8±15.1) %,占椎体总体积(12.9±5.6) %,上下方相比,差异均无统计学意义(P>0.05)。结论本研究定量观测并描述了PCVP术后骨水泥分布特征,并可为生物力学建模提供量化的临床数据。

Abstract: Objective To quantitatively observe the bone cement distribution characteristics after percutaneous curved vertebroplasty (PCVP). Methods The distribution areas of cement in the ipsilateral and contralateral sides in anterior?posterior X-ray were calculated and compared. Three-dimensional models of vertebral body and bone cement were established. The bone cement was segmented into ipsilateral/contralateral part by sagittal plane, and upward/downward part by axial plane. Cement volume and volume ratio of each part were calculated, and statistical analysis was performed. Results The cement distribution areas in the ipsilateral side and the contralateral side were 2.19-6.08 cm2 [(3.87±1.00) cm2] and 1.71-6.21 cm2 [(3.18±1.18) cm2], with a statistical significant difference (P<0.05). In the ipsilateral part, the mean cement volume, volume ratio to the whole cement, and volume ratio to the whole vertebral body were (4 821.7±1 151.8) mm3, (62.2±10.4) %, and (16.9±3.1) %, respectively. Same parameters in the contralateral part were (2 982.5±1 207.9) mm3, (37.8±10.4) %, and (10.8±4.2) %, respectively; differences in the parameters between the two parts were statistically significant (P<0.05). These parameters in the upward part were (4 242.9±1 165.8) mm3, (55.2±15.1) %, and (14.9±3.5) %, respectively, compared to the downward part as (3 574.3±1 539.7) mm3, (44.8±15.1) %, and (12.9±5.6) %, respectively, with no statistical significance (P>0.05). Conclusion Through quantitatively observing and describing the characteristics of cement distribution after PCVP, the study provides quantitative data for biomechanical modeling.
