The use of larger femoral head size in total hip arthroplasty (THA) has increased during the
past decade; 32 mm and 36 mm are the most commonly used femoral head sizes, as …

Aims To present a surgically relevant update of trunnionosis. Materials and Methods
Systematic review performed April 2017. Results Trunnionosis accounts for approximately …

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 …

Fretting corrosion is a known failure mechanism of total hip replacement (THR) that can lead
to revision surgery. Implant retrieval studies have thoroughly documented the occurrence of …

The focus on taper corrosion in modular hip arthroplasty increased around 2007 as a result
of clinical problems with large-head metal-on-metal (MoM) bearings on standard stems …

The UK's National Joint Registry (NJR) and the American Joint Replacement Registry
(AJRR) of 2022 revealed that total hip replacement (THR) is the most common orthopaedic …

Background The modular head taper junction has contributed to the success of total hip
arthroplasty (THA) greatly. Taper corrosion and wear problems reported for large and extra …

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 …
