生物力学

Moreover, these concepts were inherently tied to methods of treatment based on the use of stiff wires and heavy forces in a biomechanic approach that emphasized appliance-shape and detailed wire-bending techniques in driving the orthodontic treatment.

此外，这些概念本来就是相关的治疗方法的基础上使用的硬线和重型部队在生物力学的方法，强调设备形状和详细的钢丝弯曲技术推动矫正治疗。

Using dual energy X-ray bone density instrument XR-36 model to detect the bone mineral density of the left femur of the rats. Using the strain test system, we examined the biomechanics index according the tension and three-spot bending test; we also examined the bone calcium of the lumbar vertebra through plasma emission spectroscopy . We examined the serum calcium and magnesium by using the nomal biomechanics method,and examined the serum acid phosphatase and osteocalcin by using the Elisa method.

使用NORLAND公司XR-36型双能X线骨密度仪，采用小动物骨密度测定软件，测定大鼠左后肢股骨的骨密度；使用应变测试系统，按股骨拉伸和三点弯曲试验，测定股骨生物力学指标；以等离子体发射光谱法测定腰椎骨骨钙含量；以常规生化法测定血清钙、镁含量及血清酸性磷酸酶含量；以Elisa法测定骨钙素含量。

Biomechanics of should joint at the empty out and transition moment: In the instant of leaving of the left foot, the angle between shoulder and hip was 27°, the angle of pull was 150°, the angle of axis between shoulder was -12°; In the instant of touchdown of the right foot, the angle between shoulder and hip was 72°, the angle of pull was 151°, the angle of axis between shoulder was -85°, the speed of left shoulder was 2.43 m/s, the speed of right shoulder was

腾空和过渡阶段肩关节的生物力学指标：左脚离地瞬间肩髋角度为27 ，拉引角度为150 ，肩轴角度为-12 ；右脚着地瞬间肩髋角度为72 ，拉引角度为151 ，肩轴角度为-85 ，左肩速度为2.43m／s、右肩速度为1.37m／s；左脚着地瞬间肩髋角度为58 ，拉引角度为136 ，肩轴角度为19 ，左肩速度为3.49m／s，右肩速度为1.89m／s。

The data of femur biodymamics showed that acupuncture and moxibustion could increase the biggest load, modulus of elasticity, the biggest flexibility. The data of shank bone morphometry showed that acupuncture and moxibustion could increase percentage of bone trabecula bulk, lessen percentage of bone trabecula absorption and restoration, slow the rate of bone trabecula mineralization. Slices indicated that the structure of bone trabecula became basically complete.

股骨骨生物力学参数显示，针灸可提高OP症大鼠股骨最大载荷、弹性模量和最大挠度；胫骨骨组织形态计量学指标显示，针灸可增加骨小梁体积百分比，减少骨小梁吸收表面百分比和骨小梁形成表面百分比，降低骨小梁矿化沉积速率；胫骨骨组织切片显示，针灸后大鼠骨小梁结构已基本完整。

Cases recovered completely, and some various complications occurred in 14 cases. Conclusion Harrington rod is an effective internal fixation device for the reduction of fracture and dislocation of vertebra with its longitudinal stress. This device corresponds to the biomechanics of the spinal column. But during the operation, complications should be avoided or diminished by performing strict aseptic technique, bending of the rod to a proper physiological curvature which corresponds to injured spine, doing posterior bone grafting and using corset support after operation.

结论哈氏棒是一种符合生物力学的内固定器材，具有较强的纵向撑开力，能使骨折脱位得到很好复位，但亦具有一些缺点，如术中能做到置钩前预制好骨孔，并将哈氏棒预弯成与伤段脊柱相应的生理弧度，加用钢丝固定双棒，行后路植骨融合，术后使用支架保护，严格无菌操作等，可大大降低并发症的发生。
