Wear of different materials for total hip replacement under adverse stop-dwell-start in vitro wear simulation conditions

Autor: John Fisher, Graham Isaac, Megan Hadley, C. Hardaker

Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine. 232:1261-1270

Hip simulation is a common technique for pre-clinical evaluation of wear performance of total hip arthroplasty. Standard techniques replicate kinematics of walking patterns of a typical patient. Attention has focussed in developing simulations of oth

Validation of ion level analysis as method to assessin vitrototal hip replacement wear

Autor: S. Williams, F. Loughran, John P. Fisher, C. Hardaker, Graham Isaac, Ian Leslie

Publikováno v: Tribology - Materials, Surfaces & Interfaces. 2:104-108

Currently in vitro hip simulator wear of metal on metal hip replacements is carried out by gravimetric means. However, this is time consuming and cannot be used to assess wear between measurement intervals. Measuring ion levels (Co and Cr) by inducti

The influence of simulator input conditions on the wear of total knee replacements: An experimental and computational study

Autor: Louise M. Jennings, C. Hardaker, Claire L. Brockett, John Fisher, Abdellatif Abdelgaied, Tony Haythornthwaite

Publikováno v: Proceedings of the Institution of Mechanical Engineers. Part H, Journal of Engineering in Medicine

Advancements in knee replacement design, material and sterilisation processes have provided improved clinical results. However, surface wear of the polyethylene leading to osteolysis is still considered the longer-term risk factor. Experimental wear

Head replacement, head rotation, and surface damage effects on metal-on-metal total hip replacements: A hip simulator study

Autor: Graham Isaac, Duncan Dowson, C. Hardaker

Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine. 220:209-217

The possibility of replacing the femoral head alone, in either solid or articular surface replacement form, during revision operations on metal-on-metal total hip replacements remains an attractive feature of such implants. In the present investigati
