The use of complementary non-destructive evaluation methods to evaluate the integrity of the cement—bone interface

Abstract: The integrity of the cement-bone interface is vital to the long-term stability of cemented hip arthroplasty. Most of the previous studies investigating the interface have been confined to the continuum level, neglecting the effects of microstructure. Microscopic damage at the interface may eventually lead to macroscopic loosening of the implant. However, as the strength of the interface depends on the interlock of the cement with bone and because the properties of cancellous bone depend on its microstructure, … Show more

“…Acoustic emission (AE) can measure failure initiated inside a solid by detecting sound waves produced as material undergoes post-elastic deformation from plasticity or damage. 13 During plasticity, dislocation movement and cracking releases elastic waves of energy detectable on the material’s surface by piezoelectric sensors in real time. 13 AE-detected microdamage has been verified using micro-CT (µCT).…”

“…The bone-cement interface has been extensively examined during studies investigating the longevity of hip arthroplasty procedures. [31][32][33][34][35][36][37] These studies used detailed micro-mechanical FE models to study the effect of cement shrinkage, friction, bone damage and fatigue loading on local stress levels within the interface region. These studies also utilised digital image correlation techniques during experimental work to examine the tensile and shear properties of bone-cement composites.…”
