AbstractObjectives1 Correlate bone mineral densityto vertebral compressive strengths.2 Consummate the technique for percutaneous polymethylmethacrylate vertebroplasty and observe the pattern of PMMA imaging distribution.3 Determine the strength and stiffness of osteoporotic with or without vertebroplasty with PMMA bone cement.4 Correlation of BMD,insertion torque and pull-out strengths of pedicle screws.5 Ascertain whether augmentation with PMMA bone cement can enhance pedicle screw fixation in the osteoporotic spine.6 Ascertain whether augmentation pedicle screw fixation with PMMA bone cement can enhance the stability of unstable thoracolurner burst fractures of osteoporotic spine.

目 的1、测试椎体压缩强度，分析强度与骨矿物质密度（bone mineral density，BMD）的相关关系。2、观察经皮椎体成形术后聚甲基丙烯酸甲脂（polymethylme- thacrylate，PMMA）骨水泥在椎体内的形态学分布及影像学表现。3、比较PMMA骨水泥骨质疏松椎体成形术前/后椎体最大抗压力和压缩刚度的变化。4、分析椎体BMD、螺钉最大旅入力矩和最大拔出力三者之间的关系。5、分析PMMA骨水泥强化骨质疏松椎弓根螺钉后的螺钉的最大轴向拔出力和拔出刚度的变化。6、评价PMMA骨水泥强化骨质疏松椎弓根螺钉脊柱内固定对不稳定型胸腰椎损伤的即刻稳定性和反复载荷后的稳定性。
