Experimental micromechanics of the cement-bone interface.
Despite the widespread use of cement as a means of fixation of implants to bone, surprisingly little is known about the micromechanical behavior in terms of the local interfacial motion. In this work, we utilized digital image correlation techniques to quantify the micromechanics of the cement-bone interface of laboratory-prepared cemented total hip replacements subjected to nondestructive, qua...
متن کاملInterface micromechanics of transverse sections from retrieved cemented hip reconstructions: an experimental and finite element comparison
In finite element analysis (FEA) models of cemented hip reconstructions, it is crucial to include the cement-bone interface mechanics. Recently, a micromechanical cohesive model was generated which reproduces the behavior of the cement-bone interface. The goal was to investigate whether this cohesive model was directly applicable on a macro level. From transverse sections of retrieved cemented ...
متن کاملThe Cement-Bone Interface: A Comparative Experimental and Finite Element Study
INTRODUCTION: Cement augmentation techniques, such as vertebroplasty, are increasingly being used in the treatment of bony fractures. The rise of such procedures, along with the continued use of cement in total joint replacement, have led to increased interest in the behavior of the bone-cement interface. This region is critical in the performance of joint replacement devices and the load trans...
متن کاملMicromechanics of postmortem-retrieved cement-bone interfaces.
The cement-bone interface plays an important role in load transfer between cemented implant systems and adjacent bone, but little is known about the micromechanical behavior of this interface following in vivo service. Small samples of postmortem-retrieved cement-bone specimens from cemented total hip replacements were prepared and mechanically loaded to determine the response to tensile and co...
متن کاملMixed-mode loading of the cement-bone interface: a finite element study.
While including the cement-bone interface of complete cemented hip reconstructions is crucial to correctly capture their response, its modelling is often overly simplified. In this study, the mechanical mixed-mode response of the cement-bone interface is investigated, taking into account the effects of the well-defined microstructure that characterises the interface. Computed tomography-based p...
