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。

Bone remodeling appears to be governed by a feedback system in which the bone cells sense the state of strain in the bone matrix around them and either add or remove bone as needed to maintain the strain within normal limits.

骨骼的重新塑造由一套反馈系统管理，在该系统中，骨骼细胞感觉到它周围的骨骼基质的拉紧状况，按照需要要么增加要么移动骨骼来在标准范围中维持这个状况。

Measuring bone speed of sound was developed. This method measure bone density, and other bone properties such as cortical thickness, elasticity and micro-architecture, thus providing a more complete picture of bone strength.

In school children, tibial bone strength of obese group and overweight group, normal weight group was in the increasing order; the descending risk of bone strength in obese and overweight group was 9.73 and 2.54 times of normal group respectively. Radialis bone strength of obese group was worse than overweight group and normal weight group, while the bone strength of overweight group and normal weight group was not different.
