ALN had reasonable mechanic distribution, low stress shielding rate and fixation stability, also was easy to operate with rapid rehabilitation.
ALN钉具有力学分布合理、应力遮挡小、内固定稳定可靠，手术操作方便，能早期恢复伤肢功能的特点。
Objective: To approach the change of stress shielding rate of internal fixation materials made of nano zirconia gradient compounded with hydroxyapatite.
目的：探讨氧化锆梯度复合羟基磷灰石内固定材料的应力遮挡率的变化。
The stress shielding rate, bending strength of different directions and torsion strength of the three different fixation methods were measured and compared.
然后对三种固定方法对固定骨段的应力遮挡率、不同加载方向的弯曲强度和扭转强度进行测试。
