In replacement surgery of the hip joint, an implant is replaced into the natural femur which
recreates the articulation and functionally of a natural joint. Total hip replacement is …

Background Recent studies have attributed adverse local tissue reactions (ALTRs) in
patients with total hip arthroplasties (THAs) to tribocorrosion debris generated by modular …

Total hip arthroplasty (THA) implant usage has evolved as experience has been gained with
newer implant designs. The purpose of this study was to characterize trends in THA implant …

Background Positioning of total hip bearings involves tradeoffs, because cup orientations
most favorable in terms of stability are not necessarily ideal in terms of reduction of contact …

Taperosis/trunnionosis is a scientific term for describing tribocorrosion (fretting corrosion) at
the head-neck taper junction of hip implants where two contacting surfaces are undergone …

There is increasing global awareness of adverse reactions to metal debris and elevated
serum metal ion concentrations following the use of second generation metal-on-metal total …

Background: Modular femoral heads provide procedural enhancement by allowing accurate
restoration of hip offset and limb-length equalization. However, corrosion may lead to …

This study proposes a new finite element (FE) model for tribocorrosion at the head-neck
junction of hip implants (known as taperosis). The model addresses the synergy in …

Wear is one of the main reasons for failure of modular total hip replacements. Recent
evidence suggests that fretting wear occurs at the taper junction which provides fixation …

Present research aims to develop a finite element computational model to examine
delamination-fretting wear behaviour that can suitably mimic actual loading conditions at …
