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。
