1) Low stress-shielding
低应力遮挡
2) stress-shielding
应力遮挡
1.
The influence of stress-shielding at the proximal femur on human osteoblast proliferation and apoptosis
股骨假体近端应力遮挡对成骨细胞增殖和凋亡的影响
2.
The phenomenon of stress-shielding had been found in different materials,such as 316L stainless steel,CoCrMo alloy and Ti6Al4V alloy,and stress decrease during elastic module increase was found in these mate.
结果表明:目前临床采用的Ti6Al4V、316L和CoCrMo假体材料均具有应力遮挡现象,只是弹性模量不同遮挡会产生差异,具体表现为弹性模量越高遮挡越明显;对PMMA和CAP两种骨水泥固定的假体进行分析后得出,采用骨水泥固定方法的股骨所受到的应力数值要大于生物学(无骨水泥)固定方法下的股骨,骨水泥对于减少应力遮挡有一定的作用,对于术后假体的固定和患者的康复均具有积极的作用。

However, the mismatch between the modulus of metallic bone plates and the cortical bone leads to "stress-shielding effect",which causes the restored bone brittle and loose, and might refracture occasionally, sometimes 20% probability after bone plate removal.
目前，内椄骨板主要采用金属材料，但金属材料模量比骨的模量高很多，会引起“应力遮挡”，影响骨折愈合过程和愈合后骨的强度，愈合结束，骨板取出后，由此引起的原骨折区再次骨折的几率甚至高达20％。
3) Stress shielding
应力遮挡
1.
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。
2.
Many researchers consider that both the mechanics and the biology factors can cause the loosening, for example, the stress shielding and wearing chippings.
国内外研究认为, 无菌松动的原因分两大类,力学因素和生物因素,例如应力遮挡和磨损微粒碎屑等。
3.
The high elastic modulus of rigid internal fixator can cause stress shielding, which is not good to fracture healing and rebuilding.
但目前临床使用的钛及钛合金材料本身具有的高弹性模量使其在固定中会引发应力遮挡效应,由此影响了骨的正常愈合和改建。
4) Stress protection
应力遮挡
1.
It can reduce stress protection and avoid re-fracture after steel plat removal.
ＣＦＲＰ具弹性模量与骨相近似的特点应用 骨折内固定可以减少应力遮挡，避免钢板取出后的再骨折，有利于骨折愈合。
5) non-stress shielding
无应力遮挡
6) stress-shielding effect
应力遮挡效应
1.
The objective of this study is to further verify the rapid bone healing with high quality under the internal fixation of swan-like memory compressive connector(SMC), to explore the related mechanism of SMC on promoting fracture healing and to evaluate the stress-shielding effect and biological compatibility of SMC from clinical aspects.
为进一步验证天鹅型记忆接骨器固定下的快速高质量的骨愈合,阐述其对骨折愈合的影响及相关机理,并从临床研究角度评价SMC的应力遮挡效应和生物相容性,进行本课题研究。
补充资料：低应力脆断
分子式：
CAS号：
性质：当容器或构件采用强度高而韧性差的材料时，在应力水平不高，甚至低于材料屈服极限的情况下所发生的突然断裂现象称为低应力脆断。这类现象在使用温度较低而且选材不当时，往往发生在材料存在缺陷的地方。
