The indication for femoral stem cementation should be made on a patient-specific basis,
taking physical activity, femoral geometry, and bone tissue quality into account. Age alone …

The integrity of the cemented fixation interface is responsible for the long-term longevity of
artificial hip prostheses. Metallic stems with roughened surfaces are considered to provide …

PMMA polymerization is an exothermic phenomenon during which stresses and porosity are
observed. An experimental model is devised to directly measure radial forces, to be …

Background: Shape-closed cemented implants rely on a stronger bond and have displayed
inferior clinical outcomes when compared to force-closed designs. Implant contamination …

We investigated the effect of pre-heating a femoral component on the porosity and strength
of bone cement, with or without vacuum mixing used for total hip replacement. Cement …

The initial fixation of a cemented hip implant relies on the strength of the interface between
the stem, bone cement and adjacent bone. Bone cement is used as grouting material to fix …

Both clinical examinations and in vitro physical experiments have shown that the fixation
interfaces of cemented components are actually critical sites affecting the long-term stability …

Interfacial defects between the cement mantle and a hip implant may arise from constrained
shrinkage of the cement or from air introduced during insertion of the stem. Shrinkage …

The importance of the conditions at the stem-cement interface in cemented total joint
replacements (THRs) with regard to the in vivo longevity of the implant is well recognized. In …

Background Aseptic loosing is one of the most important failure scenarios in orthopedics
and cement damage accumulation is an indicator of potential mechanical failure of cement …
